Noninvasive monitoring of liver cell transplantation
Stacks Image 11882
Our latest review on „Noninvasive monitoring of liver cell transplantation“ (authors are N. Raschzok, H.M. Morgül, L. Stelter & I.M. Sauer) is available in Imaging in Medicine, 2013; 5: 47-61:
Liver cell transplantation was developed as a therapeutic alternative to solid liver transplantation in the management of liver-based metabolic disorders and may be useful for the treatment of acute or chronic liver failure. While clinical studies have demonstrated temporal amelioration of the symptoms of metabolic liver disorders by transplanted liver cells, the long-term outcome of liver cell transplantation is still insufficient. A major limitation for improving liver cell transplantation is the inability to track the fate of cells once they have been infused. Radionuclide-based imaging, MRI and optical methods have been investigated as methods for noninvasive monitoring of liver cell transplantation. This article summarizes and critically discusses these approaches, with a special focus on MRI-based tracking of transplanted liver cells and provides an outlook on possible clinical applications for the near future.

GASL Poster Prize
Stacks Image 11912
Nathanael Raschzok's poster entitled "Serum protein biomarkers for acute rejection
in liver transplantation" was awarded with the GASL 2013 poster prize during the 29th Annual Meeting of the German Association for the Study of the Liver (GASL) in Hannover, Germany. Co-authors are Kukuh A. Prabowo, Anja Reutzel-Selke, Rosa B. Schmuck, Mehmet H. Morgul, Laura M. Tannus, Stephanie König, Sven Jonas, Peter Neuhaus, and Igor M. Sauer.


Although 20–40% of patients experience at least one episode of acute rejection (AR) after liver transplantation (LTx), diagnosis of AR is still mainly based on tissue analysis from liver biopsies. Biomarker routinely taken from blood samples would be a powerful non-invasive tool for monitoring of the liver graft status. The aim of this study was to investigate the diagnostic and prognostic value of serum protein biomarkers for acute rejection in LTx recipients. Serum samples from n=20 patients with AR and n=15 stable controls were analyzed. CXCL9 and CD31 were up-regulated in AR samples compared to controls at the time point of histologically proven rejection and at earlier time points prior rejection. Areas under the Receiver Operation Characteristics (ROC) curves were 0.6 and 0.7 at the day of rejection and 0.8 at POD1 for CXCL9 and CD31, respectively. IL-6 was increased prior and during rejection, while CD44 showed an opposite trend.
Serum protein biomarkers could be valuable for detection and prediction of AR after LTx. However, a larger number of patients, additional control groups, and prospective clinical trials will be necessary to proof the clinical utility of this diagnostic tool.

Moreover, Rosa Schmuck presented her data on "Bile: miRNA pattern and cell morphology as a diagnostic tool after liver transplantation" (co-authors: Nathanael Raschzok, Anja Reutzel-Selke, Steffen Lippert, Stephanie König, Kukuh A. Prabowo, Mehmet H. Morgul, Laura M. Tannus, Sven Jonas, Peter Neuhaus, and Igor M. Sauer) and Luisa Lisboa her work on "MicroRNA miR-352 in early liver regeneration: what role?" (co-authors: Nathanael Raschzok, Annekatrin Leder, Natalie Schlüter, Marc Jörres, Susanne Kolano, Antje Butter, Steffen Lippert, Wiebke Werner, Peter Neuhaus, and Igor M. Sauer).

MRI and ectopic liver cell transplantation - new paper
Stacks Image 11960
Nathanael Raschzok’s latest paper on „Feasibility of fast dynamic MRI for noninvasive monitoring during ectopic liver cell transplantation to the spleen in a porcine model“ is now available in AJR Am J Roentgenol. 2012 Jun;198(6):1417-23.
Liver cell transplantation is a promising approach for the treatment of metabolic liver disorders. However, a method for noninvasive monitoring during liver cell transplantation is not available clinically. The aim of this study was to investigate the feasibility of fast dynamic MRI monitoring during liver cell infusion to the spleen, which is considered an ectopic implantation site for liver cell transplantation. Porcine liver cells were labeled with micron-sized iron oxide particles and infused to the spleens of pigs (n = 5) via the lineal artery. MRI was performed using a 3-T MR scanner. Initially, T1- and T2-weighted pulse sequences were tested. Thereafter, fast dynamic MRI was performed during cell infusion. MR findings were verified by immunohistological examinations.

Images from static MRI (TR/TE, 2500/105.2) showed significantly lower signal intensity and signal-to-noise ratio after cell infusion compared with pretransplant images. T2-weighted fast dynamic MRI enabled visualization of signal decrease of the spleen during cell infusion. When cells were infused systemically, no signal changes in the spleen were observed. This study shows that fast dynamic MRI can enable noninvasive monitoring during liver cell transplantation to the spleen. This approach could be useful for preclinical studies and for quality control of clinical liver cell transplantation.

R.B.V. Schmuck received Charité Robert-Koch-Prize 2012
Today, Rosa Schmuck received the 2012 Charité Robert-Koch-Prize for her doctoral thesis entitled „Genotypic and phenotypic characterization of side population of gastric cancer cell lines“ (group of Prof. C. Röcken).

The Side Population (SP) of tumor cell lines shares characteristics with tumor stem cells. In this study we phenotypically and genotypically characterized the SP of gastric cancer cell lines. SPs were obtained from MKN45- and AGS-gastric cancer cells using Hoechst 33342 staining and fluorescence-activated cell sorting (FACS). SP cells were subsequently studied morphologically (cytology, immunocytochemistry), on the transcriptional level (gene array) and in cell culture (recultivation assays). Genes differentially expressed in the SP cells were evaluated by immunohistochemistry in tissue from gastric cancer patients. SP cells were smaller and rounder then Non-SP cells. SP cells self-renewed in re-cultivation experiments and differentiated into SP- and Non-SP cells. Re-cultivated SP- and Non-SP cells showed distinct phenotypes in culture regarding cell shape and colony-formation. SP cells had increased levels of the stem cell markers CD133 and Musashi1. Transcriptional analyses demonstrated that SP cells express genes that encode for stem cell properties like FZD7, HEY1, SMO and ADAM17. Finally she found ADAM17 and FZD7 to be differentially expressed in human gastric cancer, with FZD7- positive intestinal type cancers showing a significant shorter patient survival. In conclusion human gastric cancer cell lines enclose a phenotypically and genotypically distinct cell population with tumor stem cell features. Phenotypical characteristics of this distinct cell population are also present in gastric cancer tissue and seem to correlate with patient survival.

Following a successful project sponsored by the BMBF G. Pless, I.M. Sauer and U. Rauen report on the "Improvement of the cold storage of isolated human hepatocytes" (Cell Transplant. 2011 Jun 7. [Epub ahead of print]).
Increasing amounts of human hepatocytes are needed for clinical applications and different fields of research, such as cell transplantation, bioartificial liver support and pharmacological testing. This demand calls for adequate storage options for isolated human liver cells. As cryopreservation results in severe cryoinjury, short term storage is currently performed at 2-8º C in preservation solutions developed for the storage of solid organs. However, besides slowing down cell metabolism, cold also induces cell injury, which is, in many cell types, iron-dependent and not counteracted by current storage solutions. In this study, we aimed to characterize storage injury to human hepatocytes and develop a customized solution for cold storage of these cells. Human hepatocytes were isolated from material obtained from partial liver resections, seeded in monolayer cultures and, after a pre-culture period, stored in the cold in classical and new solutions followed by rewarming in cell culture medium.Human hepatocytes displayed cold-induced injury, resulting in > 80% cell death (LDH release) after one week of cold storage in University of Wisconsin solution or cell culture medium and 3 h of rewarming. Cold-induced injury could be significantly reduced by the addition of the iron chelators deferoxamine and LK 614. Experiments with modified solutions based on the new organ preservation solution Custodiol-N showed that ion-rich variants were better than ion-poor variants, chloride-rich solutions better than chloride-poor solutions, potassium as main cation superior to sodium and pH 7.0 superior to pH 7.4. LDH release after two weeks of cold storage in the thus optimized solution was below 20%, greatly improving cold storage of human hepatocytes. The results were confirmed by the assessment of hepatocellular mitochondrial membrane potential and functional parameters (resazurin reduction, glucacon-stimulated glucose liberation) and thus suggest the use of a customized hepatocyte storage solution for the cold storage of these cells.

Fast dynamic MRI during liver cell Tx
Stacks Image 12072
Micrometer-sized iron oxide particles (MPIOs) attract increasing interest as contrast agents for cellular tracking by clinical Magnetic Resonance Imaging (MRI). Despite the great potential of MPIOs for in vivo imaging of labeled cells, little is known on the intracellular localization of these particles following uptake due to the lack of techniques with the ability to monitor the particle uptake in vivo at single-cell level. Here, we show that coherent anti-Stokes Raman scattering (CARS) microscopy enables non-invasive, label-free imaging of MPIOs in living cells with sub-micron resolution in three dimensions. CARS allows simultaneous visualization of the cell framework and the MPIOs, where the particles can be readily distinguished from other cellular components of comparable dimensions, and localized inside the cell.
The fruitful cooperation with the FOM Institute AMOLF in Masterdam resulted in the paper "CARS microscopy for the visualization of micrometer-sized iron oxide MRI contrast agents in living cells" (Rago G, Langer CM, Brackman C, Day JP, Domke KF, Raschzok N, Schmidt C, Sauer IM, Enejder A, Mogl MT, Bonn M.) published in Biomed Opt Express. 2011 Sep 1;2(9):2470-83.

As a first result of our latest projects concerning the role of miRNA in liver regeneration the American Journal of Physiology - Regulatory, Integrative and Comparative Physiology has accepted our paper "Temporal expression profiles indicate a primary function for microRNA during the peak of DNA replication after rat partial hepatectomy": The liver has the unique capacity to regenerate after surgical resection. However, the regulation of liver regeneration is not completely understood. Recent reports indicate an essential role for small non-coding microRNAs (miRNAs) in the regulation of hepatic development, carcinogenesis, and early regeneration. We hypothesized that miRNAs are critically involved in all phases of liver regeneration after partial hepatectomy. We performed miRNA microarray analyses after 70% partial hepatectomy in rats under isoflurane anesthesia at different time points (0 hours - 5 days) and after sham laparotomy. Putative targets of differentially expressed miRNAs were determined using a bioinformatic approach. 2D-PAGE proteomic analyses and protein identification were performed on specimens at 0 and 24 hours after resection. The temporal dynamics of liver regeneration were characterized by BrdU, PCNA, IL-6, and HGF. We demonstrate that miRNA expression patterns changed during liver regeneration and that these changes were most evident during the peak of DNA replication at 24 hours after resection. Expression of thirteen miRNAs was significantly reduced 12-48 hours after resection (> 25% change), ouf of which downreguation was confirmed in isolated hepatocytes for 6 miRNAs at 24 hours, whereas three miRNAs were significantly upregulated. Proteomic analysis revealed 65 upregulated proteins; among them 23 represent putative targets of the differentially expressed miRNAs. We provide a temporal miRNA expression and proteomic dataset of the regenerating rat liver, which indicates a primary function for miRNA during the peak of DNA replication. These data will assist further functional studies on the role of miRNAs during liver regeneration. Authors are N. Raschzok, W. Werner, H. Sallmon, N. Billecke, C. Dame, P. Neuhaus and I.M. Sauer.

Our latest paper on "Monitoring of liver cell transplantation in a preclinical swine model using magnetic resonance imaging" has been accepted for publication in CELL Medicine (Part B of CELL TRANSPLANTATION). Authors are Nathanael Raschzok, Ulf Teichgräber, Nils Billecke, Anja Zielinski, Kirsten Steinz, Nora N. Kammer, Mehmet H. Morgul, Sarah Schmeisser, Michaela K. Adonopoulou, Lars Morawietz, Bernhard Hiebl, Ruth Schwartlander, Wolfgang Rüdinger, Bernd Hamm, Peter Neuhaus and Igor M. Sauer. The study was based on the excellent colaboration with the department of Radiology and the Institute of Pathology, both Charité - Campus Mitte, Universitätsmedizin Berlin, Berlin, Germany, the Centre for Biomaterial Development and Berlin-Brandenburg Centre for Regenerative Therapies (BCRT), Institute for Polymer Research, GKSS Research Centre Geesthacht GmbH, Teltow, Germany, the Department of Materials, ETH Zurich, Zurich, C Switzerland, and Cytonet GmbH, Weinheim, Germany.
Liver cell transplantation (LCT) is a promising treatment approach for certain liver diseases, but clinical implementation requires methods for non-invasive follow-up. Labeling with superparamagnetic iron oxide particles can enable the detection of cells with magnetic resonance imaging (MRI). We investigated the feasibility of monitoring transplanted liver cells by MRI in a preclinical swine model and used this approach to evaluate different routes for cell application. Liver cells were isolated from landrace piglets and labeled with micron-sized iron oxide particles (MPIO) in adhesion. Labeled cells (n = 10), native cells (n = 3) or pure particles (n = 4) were transplanted to minipigs via intraportal infusion into the liver, direct injection into the splenic parenchyma, or intra-arterial infusion to the spleen. Recipients were investigated by repeated 3.0 Tesla MRI and computed tomography angiography up to 8 weeks after transplantation. Labeling with MPIO, which are known to have a strong effect on the magnetic field, enabled non-invasive detection of cell aggregates by MRI. Following intraportal application, which is commonly applied for clinical LCT, MRI was able to visualize the microembolization of transplanted cells in the liver that were not detected by conventional imaging modalities. Cells directly injected into the spleen were retained, whereas cell infusions intraarterially into the spleen led to translocation and engraftment of transplanted cells in the liver, with significantly fewer microembolisms compared to intraportal application. These findings demonstrate that MRI can be a valuable tool for non-invasive elucidation of cellular processes of LCT and - if clinically applicable MPIO are available - for monitoring of LCT under clinical conditions. Moreover, the results clarify mechanisms relevant for clinical practice of LCT, suggesting that the intra-arterial route to the spleen deserves further evaluation.

Hannelore Ringe published the investigations concerning the applicability, efficacy, and safety of single-pass albumin dialysis in children ("Continuous veno-venous single-pass albumin hemodiafiltration in children with acute liver failure." Pediatr Crit Care Med. 2010 Oct 1. [Epub ahead of print]). Co-authors are Varnholt V, Zimmering M, Luck W, Gratopp A, König K, Reich S, Sauer IM, Gaedicke G, and Querfeld U.
The paper reports on a retrospective data review of uncontrolled clinical data of an university-based pediatric intensive care unit collaborating with a local center for liver transplantation. Nine children, aged 2 to 15 yrs, who were treated with single-pass albumin dialysis for acute liver failure of various origins under a compassionate-use protocol between 2000 and 2006. All patients met high-urgency liver transplantation criteria. Single-pass albumin dialysis was performed as rescue therapy for children with acute liver failure. The decrease in hepatic encephalopathy (grades 1-4) and the serum levels of bilirubin, bile acids, and ammonium were measured to assess the efficacy of detoxification. As a measure of liver synthesis function, thromboplastin time and fibrinogen were analyzed. The safety of the procedure was assessed by documenting adverse effects on mean arterial blood pressure, platelet count, and clinical course. Seven out of nine patients were bridged successfully to either native organ recovery (n = 1) or liver transplantation (n = 7), one of them twice. Six out of nine patients undergoing single-pass albumin dialysis (ten treatments) survived. In six patients, hepatic encephalopathy could be reduced at least by one degree. Ammonium, bilirubin, and bile acid levels decreased in all patients. One patient had an allergic reaction to albumin. In childhood acute liver failure, treatment with single-pass albumin dialysis was generally well tolerated and seems to be effective in detoxification and in improving blood pressure, thus stabilizing the critical condition of children before liver transplantation and facilitating bridging to liver transplantation. It may be beneficial in avoiding severe neurologic sequelae after acute liver failure and thereby improve survival. Single-pass albumin dialysis is an inexpensive albumin-based detoxification system that is easy to set up and requires little training. Whether and to what extent single-pass albumin dialysis can support children with acute liver failure until native liver recovery remain unclear.

Hypothermia-induced cell protection & microglial cells
Stacks Image 12173
The European Journal of Neuroscience published the paper "Mechanisms of hypothermia-induced cell protection mediated by microglial cells in vitro" First author is Antje Diestel from Katharina Schmitt's group - co-authors are Silke Troeller, Nils Billecke, Igor M. Sauer, Felix Berger and Katharina R. L. Schmitt.
Despite the widespread interest in the clinical applications of hypothermia, the cellular mechanisms of hypothermia-induced neuroprotection have not yet been clearly understood. Therefore, the aim of this study was to elucidate the cellular effects of clinically relevant hypothermia and rewarming on the morphological and functional characteristics of microglia. Microglial cells were exposed to a dynamic cooling and rewarming protocol. For stimulation, microglial cells were treated with 1 μg/mL lipopolysaccharide (LPS). We found that hypothermia led to morphological changes from ramified to ameboid cell shapes. At 2 h after hypothermia and rewarming, microglial cells were again ramified with extended branches. Moreover, we found enhanced cell activation after rewarming, accompanied by increased phagocytosis and adenosine triphosphate consumption. Interestingly, hypothermia and rewarming led to a time-dependent significant up-regulation of the anti-inflammatory cytokines interleukin-10 and interleukin-1 receptor antagonist in stimulated microglial cells. This is in line with the reduced proliferation and time-dependent down-regulation of the pro-inflammatory cytokines tumor necrosis factor-alpha and monocyte chemotactic protein-1 in comparison to normothermic control cells after LPS stimulation. Furthermore, degradation of the inhibitor of the nuclear transcription factor-kappaB (IkappaB-alpha) was diminished and delayed under conditions of cooling and rewarming in LPS-stimulated microglial cells. Thus, our results show that hypothermia and rewarming activate microglial cells, increase phagocytosis and shift the balance of cytokine release in stimulated microglial cells towards the anti-inflammatory cytokines. This could be a new cellular mechanism of hypothermia-induced neuroprotection mediated by activated microglial cells.

Modified nanoparticles & multimodal imaging
Stacks Image 12190
Lars Stelter's studies on In vitro and in vivo detectability of modified superparamagnetic nanoparticles for multimodal imaging using fluorescence microscopy, 3T MRI and animal PET are published in the latest issue of Molecular Imaging & Biology (Mol Imaging Biol. 2010 Jan-Feb;12(1):25-34). Co-authors are Jens Pinkernelle, Roger Michel, Ruth Schwartländer, Nathanael Raschzok, Mehmet H. Morgul, Martin Koch, Timm Denecke, Holger Amthauer, Juri Ruf, Andreas Jordan, Bernd Hamm, Igor M. Sauer, Ulf Teichgräber.
Cell transplantation is a major field in regenerative medicine and a promising alternative to whole organ transplantation. However, the process of cell engraftment is not yet fully understood and the hitherto achieved clinical outcome is limited. The aim of our study was to modify an aminosilan-coated nanoparticle for cell labeling and make it applicable for multimodal imaging using MRI, PET and fluorescent imaging. HIV-1 tat, linked FITC, and Gallium-68 were covalently bound to the particle and injected into Wistar rats. Animal-PET imaging was performed followed by MRI at 3.0T. Hepatic accumulation of the particles was proven by radionuclide distribution after 10 minutes in PET as well as in MRI over a 24 hour-period. Histological workup of the liver also revealed content of iron oxide particles in the reticuloendothelial system. Adjacent in vitro studies incubating hepatogenic HuH7 cells with the particles showed a rapid intracellular accumulation, clearly detectable by fluorescence microscopy and MRI. In conclusion our modified nanoparticle is stable under in vitro and in vivo conditions and is applicable for multimodal molecular imaging. Cellular labeling with this particle is possible and might help to get new insights into understanding the process of cell transplantation.

A clonal cell line that combines both stable hepatic function and proliferation capacity is desirable for in vitro applications that depend on hepatic function, such as pharmacological or toxicological assays and bioartificial liver systems. The article describes the generation and characterization of a clonal human cell line for in vitro hepatocyte applications.Cell clones derived from human fetal liver cells were immortalized by over-expression of telomerase reverse transcriptase. The resulting cell line, cBAL111, displayed hepatic functionality similar to the parental cells prior to immortalization, and did not grow in soft agar. Cell line cBAL111 expressed markers of immature hepatocytes, like glutathione S transferase and cytokeratin 19, as well as progenitor cell marker CD146 and was negative for lidocaine elimination. On the other hand, the cBAL111 cells produced urea, albumin and cytokeratin 18 and eliminated galactose. In contrast to hepatic cell lines NKNT-3 and HepG2, all hepatic functions were expressed in cBAL111, although there was considerable variation in their levels compared with primary mature hepatocytes. When transplanted in the spleen of immunodeficient mice, cBAL111 engrafted into the liver and partly differentiated into hepatocytes showing expression of human albumin and carbamoylphosphate synthetase without signs of cell fusion. This novel liver cell line has the potential to differentiate into mature hepatocytes to be used for in vitro hepatocyte applications.

Nathanael Raschzok defended thesis "summa cum laude"
Stacks Image 12269
Nathanael Raschzok successfully defended his medical doctoral thesis "summa cum laude". After three years of extremely fruitful research and development in the field of hepatocyte transplantation, cell labeling, and MR imaging of transplanted cells he is first author of three papers in peer reviewed journals (with more to come...). He currently is finishing his in vivo MRI studies of MPIO labeled transplanted hepatocytes.
Transplantation of primary human hepatocytes is a promising approach in certain liver diseases. For visualisation of hepatocytes during and following cell application and the ability of a timely response to potential complications, a non-invasive modality for imaging of the transplanted cells has to be established. The aim of his studies was to label primary human hepatocytes with micron-sized iron oxide particles (MPIOs), enabling the detection of cells by clinical magnetic resonance imaging (MRI). The feasibility of preparing MPIO-labelled primary human hepatocytes detectable by clinical MR equipment was shown in vitro. MPIO-labelled cells could serve for basic research and quality control in the clinical setting of human hepatocyte transplantation.
He also investigated techniques for evaluation of the particle uptake via continuum source atomic absorption spectrometry (CSAAS). Porcine liver cells were labelled with MPIOs and the iron concentration of the cell samples was investigated by a CSAAS spectrometer equipped with a Perkin-Elmer THGA graphite furnace. CSAAS enabled rapid quantification of particle load from small quantities of cells without extensive preparation steps. CSAAS could be used for quality control in a clinical setting of cell transplantation.

Hypothermia induced endothelial dysfunction
Stacks Image 12279
Antje Diestel's manuscript entitled "Tacrolimus and methylprednisolone prevent hypothermia induced endothelial dysfunction" has been accepted for publication in the Journal of Heart and Lung Transplantation. Co-authors are Nils Billecke, Joerg Roessler, Boris Schmitt, Silke Troeller, Ruth Schwartlander, Felix Berger, Igor Maximilian Sauer and Katharina Rose Luise Schmitt.
Hypothermia is used to preserve organs for transplant and it is the oldest method to protect organs during complex pediatric cardiac surgery. Loss of tissue function and tissue edema are common complications in children undergoing cardiac surgery and heart transplantation. The present study was designed to examine the effects of methylprednisolone (MP) and Tacrolimus (TAC) on endothelial cell function and morphology after deep hypothermia and rewarming. Human umbilical vein endothelial cells (HUVECs) were pretreated with MP and/orTAC and incubated either within a specially designed bioreactor or in monolayers. They were then exposed to a dynamic cooling and rewarming protocol. Immunocytochemistry, time lapse video microscopy within the SlideReactor bioreactor system, cell permeability and adherence assays and western blot analysis were performed. Confluent endothelial cells exposed to hypothermia displayed elongated cell shapes with intercellular gap formation, increased endothelial cell-layer permeability and loss in adherence. Upon rewarming, however, endothelial cell integrity was restored. Opening and closing of intercellular gaps was dependent on ERK 1/2 activation and connexin 43 (Cx43) expression. The combined treatment with MP and TAC inhibited these hypothermia-induced changes. These results suggest that MP and TAC inhibit hypothermia induced endothelial gap formation via pERK 1/2 inhibition and connexin 43 stabilization. Application of combined drugs that affect multiple targets may therefore be considered as a possible new therapeutic strategy to prevent endothelial dysfunction after hypothermia and rewarming.

CSAAS and MPIO-labelled cells
Stacks Image 12289
As a result of the fruitful collaboration with the Institute for Analytical Sciences Berlin Nathanael Raschzok's paper on "Quantification of Cell Labelling with Micron-Sized Iron Oxide Particles Using Continuum Source Atomic Absorption Spectrometry" has been accepted by Tissue Engineering for publication. Co-authors are Nils Billecke, Nora N. Kammer, Mehmet H. Morgul, Michaela K. Adonopoulou, Igor M. Sauer, Stefan Florek, Helmut Becker-Ross, and Mao-Dong Huang.

Detection of cells after transplantation is necessary for quality control in regenerative medicine. Labelling with micron-sized iron oxide particles (MPIOs) enables non-invasive detection of single cells by magnetic resonance imaging. However, techniques for evaluation of the particle uptake are challenging. The aim of this study was to investigate continuum source atomic absorption spectrometry (CSAAS) for this purpose. Porcine liver cells were labelled with MPIOs and the iron concentration of the cell samples was investigated by a CSAAS spectrometer equipped with a Perkin-Elmer THGA graphite furnace. The weak iron line at 305.754 nm provides only about 1/600 sensitivity of the iron resonance line at 248.327 nm and was used for CSAAS measurements. Iron concentrations measured from labelled cells ranged from (5.8 ± 0.3) to (25.8 ± 0.9) pg Fe/cell, correlating to an uptake of (8.2 ± 0.5) to (25.7 ± 0.8) particles/cell. The results were verified by standardised morphometric evaluation. CSAAS enabled rapid quantification of particle load from small quantities of cells without extensive preparation steps. Thereby, CSAAS could be used for quality control in a clinical setting of cell transplantation.
