Abstract
A clinical implementation of cell-based bone regeneration in combination with scaffold materials requires the development of efficient, controlled and reproducible seeding procedures and a tailor-made bioreactor design. A perfusion system for efficient, homogeneous, and rapid seeding with human adipogenic stem cells in bone substitute scaffolds was designed. Variants concerning medium inlet and outlet port geometry, i.e. cylindrical or conical diffuser, cell concentration, perfusion mode and perfusion rates were simulated in silico. Cell distribution during perfusion was monitored by dynamic [18F]FDG micro-PET/CT and validated by laser scanning microscopy with three-dimensional image reconstruction. By iterative feedback of the in silico and in vitro experiments, the homogeneity of cell distribution throughout the scaffold was optimized with adjustment of flow rates, cell density and perfusion properties. Finally, a bioreactor with a conical diffusor geometry was developed, that allows a homogeneous cell seeding (hoover coefficient: 0.24) in less than 60 min with an oscillating perfusion mode. During this short period of time, the cells initially adhere within the entire scaffold and stay viable. After two weeks, the formation of several cell layers was observed, which was associated with an osteogenic differentiation process. This newly designed bioreactor may be considered as a prototype for chairside application.

Abstract
PURPOSE Magnetic particle imaging (MPI) is a new imaging modality that sensitively and specifically detects superparamagnetic iron oxide nanoparticles (SPIOs). MRI cell tracking with SPIOs has very high sensitivity, but low specificity and quantification is difficult. MPI could overcome these limitations. There are no reports of micron-sized iron oxide particles (MPIO) for cell tracking by MPI. Therefore, the goal was to evaluate if MPIO can be used for in vivo detection and quantification of cancer cells distributed in the mouse brain by MPI. METHODS In the first experiment mice were injected with either 2.5 × 105 or 5.0 × 105 MPIO-labeled cancer cells and MPI was performed ex vivo. In a second experiment, mice received either 2.5 × 105 or 5.0 × 104 MPIO-labeled cells and MPI was performed in vivo. In a third experiment, mice were injected with 5.0 × 104 cells, labeled with either MPIO or ferucarbotran, and MPI was performed in vivo. RESULTS MPIO-labeled cells were visible in all MPI images of the mouse brain. The MPI signal and iron content measurements were greater for brains of mice that were injected with higher numbers of MPIO-labeled cells. Ferucarbotran-labeled cells were not detected in the brain by MPI. CONCLUSION This is the first example of the use of MPIO for cell tracking with MPI. With an intracardiac cell injection, ~15% of cells will arrest in the brain vasculature. For our lowest cell injection of 5.0 × 104 cells, this was ~10 000 cells, distributed throughout the brain.

Superparamagnetic Iron Oxide Particles (VSOPs) Show Genotoxic Effects but No Functional Impact on Human Adipose Tissue-Derived Stromal Cells (ASCs). MATERIALS 2021; 14:ma14020263. [PMID: 33430323 PMCID: PMC7825809 DOI: 10.3390/ma14020263] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 12/29/2020] [Accepted: 01/04/2021] [Indexed: 12/16/2022]
Abstract
Adipose tissue-derived stromal cells (ASCs) represent a capable source for cell-based therapeutic approaches. For monitoring a cell-based application in vivo, magnetic resonance imaging (MRI) of cells labeled with iron oxide particles is a common method. It is the aim of the present study to analyze potential DNA damage, cytotoxicity and impairment of functional properties of human (h)ASCs after labeling with citrate-coated very small superparamagnetic iron oxide particles (VSOPs). Cytotoxic as well as genotoxic effects of the labeling procedure were measured in labeled and unlabeled hASCs using the MTT assay, comet assay and chromosomal aberration test. Trilineage differentiation was performed to evaluate an impairment of the differentiation potential due to the particles. Proliferation as well as migration capability were analyzed after the labeling procedure. Furthermore, the labeling of the hASCs was confirmed by Prussian blue staining, transmission electron microscopy (TEM) and high-resolution MRI. Below the concentration of 0.6 mM, which was used for the procedure, no evidence of genotoxic effects was found. At 0.6 mM, 1 mM as well as 1.5 mM, an increase in the number of chromosomal aberrations was determined. Cytotoxic effects were not observed at any concentration. Proliferation, migration capability and differentiation potential were also not affected by the procedure. Labeling with VSOPs is a useful labeling method for hASCs that does not affect their proliferation, migration and differentiation potential. Despite the absence of cytotoxicity, however, indications of genotoxic effects have been demonstrated.

Toxicity and Functional Impairment in Human Adipose Tissue-Derived Stromal Cells (hASCs) Following Long-Term Exposure to Very Small Iron Oxide Particles (VSOPs). NANOMATERIALS 2020; 10:nano10040741.

Abstract
Magnetic nanoparticles (NPs), such as very small iron oxide NPs (VSOPs) can be used for targeted drug delivery, cancer treatment or tissue engineering. Another important field of application is the labelling of mesenchymal stem cells to allow in vivo tracking and visualization of transplanted cells using magnetic resonance imaging (MRI). For these NPs, however, various toxic effects, as well as functional impairment of the exposed cells, are described. The present study evaluates the influence of VSOPs on the multilineage differentiation ability and cytokine secretion of human adipose tissue derived stromal cells (hASCs) after long-term exposure. Human ASCs were labelled with VSOPs, and the efficacy of the labelling was documented over 4 weeks in vitro cultivation of the labelled cells. Unlabelled hASCs served as negative controls. Four weeks after labelling, adipogenic and osteogenic differentiation was histologically evaluated and quantified by polymerase chain reaction (PCR). Changes in gene expression of IL-6, IL-8, VEGF and caspase 3 were determined over 4 weeks. Four weeks after the labelling procedure, labelled and unlabelled hASCs did not differ in the gene expression of IL-6, IL-8, VEGF and caspase 3. Furthermore, the labelling procedure had no influence on the multidifferentiation ability of hASC. The percentage of labelled cells decreased during in vitro expansion over 4 weeks. Labelling with VSOPs and long-term intracellular disposition probably have no influence on the physiological functions of hASCs. This could be important for the future in vivo use of iron oxide NPs.

Abstract
BACKGROUND Regenerative medicine field is still lagging due to the lack of adequate knowledge regarding the homing of therapeutic cells towards disease sites, tracking of cells during treatment, and monitoring the biodistribution and fate of cells. Such necessities require labeling of cells with imaging agents that do not alter their biological characteristics, and development of suitable non-invasive imaging modalities. PURPOSE We aimed to develop, characterize, and standardize a facile labeling strategy for engineered mesenchymal stem cells without altering their viability, secretion of FGF21 protein (neuroprotective), and differentiation capabilities for non-invasive longitudinal MRI monitoring in live mice brains with high sensitivity. METHODS We compared the labeling efficiency of different commercial iron oxide nanoparticles towards our stem cells and determined the optimum labeling conditions using prussian blue staining, confocal microscopy, transmission electron microscopy, and flow cytometry. To investigate any change in biological characteristics of labeled cells, we tested their viability by WST-1 assay, expression of FGF21 by Western blot, and adipogenic and osteogenic differentiation capabilities. MRI contrast-enhancing properties of labeled cells were investigated in vitro using cell-agarose phantoms and in mice brains transplanted with the therapeutic stem cells. RESULTS We determined the nanoparticles that showed best labeling efficiency and least extracellular aggregation. We further optimized their labeling conditions (nanoparticles concentration and media supplementation) to achieve high cellular uptake and minimal extracellular aggregation of nanoparticles. Cell viability, expression of FGF21 protein, and differentiation capabilities were not impeded by nanoparticles labeling. Low number of labeled cells produced strong MRI signal decay in phantoms and in live mice brains which were visible for 4 weeks post transplantation. CONCLUSION We established a standardized magnetic nanoparticle labeling platform for stem cells that were monitored longitudinally with high sensitivity in mice brains using MRI for regenerative medicine applications.

Abstract
Superparamagnetic iron oxide nanoparticles (SPIONs) have unique properties with regard to biological and medical applications. SPIONs have been used in clinical settings although their safety of use remains unclear due to the great differences in their structure and in intra- and inter-patient absorption and response. This review addresses potential applications of SPIONs in vitro (formulations), ex vivo (in biological cells and tissues) and in vivo (preclinical animal models), as well as potential biomedical applications in the context of drug targeting, disease treatment and therapeutic efficacy, and safety studies.

Abstract
However, labelling of stem cells using nanoparticles (NPs) for tracking purpose has been intensively investigated, the biosafety of these materials needs more clarification. Herein, different forms of iron oxide Fe2O3, Fe3O4, and CoxNi1-x Fe2O4 NPs either uncoated or starch-coated (ST-coated) were prepared. We successfully labelled adipose-derived stem cells (ASCs) using these NPs with the aid of lipofectamine as a transfection agent (TA). We then evaluated the effect of these NPs on stem cell proliferation, viability, migration and angiogenesis. Results showed that ASCs labelled with Fe2O3, Fe3O4, ST-Fe2O3 and ST-Fe3O4 did not show any significant difference in proliferation compared to that of TA-treated cells. Moreover, they have shown a protective effect against apoptosis. Conversely, CoxNi1-x Fe2O4 NPs caused a significant decrease in cell proliferation. Compared to that of the TA-treated cells, the migration capacity of cells labelled with Fe2O3, Fe3O4 and CoxNi1-xFe2O4 was significantly compromised. Interestingly, the ST-coated composites reversed this effect. Among the groups treated with different NPs, the angiogenic potential of the ASCs was most robust in the ST-Fe2O3-treated group. In conclusion, labelling ASCs with ST-Fe2O3 NPs enhanced cell migration and angiogenic potential and conferred higher resistance to apoptosis than labelling the cells with the other tested NPs.

Abstract
Pancreatic cancer is a complex disease accounting for fibrotic tumors and an aggressive phenotype. Gemcitabine (GEM) is used as a standard therapy, which develops chemoresistance leading to poor patient outcome. We have recently developed a superparamagnetic iron oxide nanoparticle (SPION) formulation of curcumin (SP-CUR), which is a nontoxic, bioactive anti-inflammatory/anti-cancer agent for its enhanced delivery in tumors. In this study, we demonstrate that SP-CUR effectively delivers bioactive curcumin to pancreatic tumors, simultaneously enhances GEM uptake and its efficacy. Mechanistic revelations suggest that SP-CUR targets tumor microenvironment via suppression of sonic hedgehog (SHH) pathway and an oncogenic CXCR4/CXCL12 signaling axis that inhibits bidirectional tumor-stromal cells interaction. Increased GEM uptake was observed due to upregulation of the human nucleoside transporter genes (DCK, hCNT) and blocking ribonucleotide reductase subunits (RRM1/RRM2). Additionally, co-treatment of SP-CUR and GEM targets cancer stem cells by regulating pluripotency maintaining stemness factors (Nanog, Sox2, c-Myc and Oct-4), and restricting tumor sphere formation. In an orthotopic mouse model, an enhanced accumulation of SP-CUR was found in pancreas, which potentiated GEM to reduce tumor growth and metastasis. Analysis of tumor tissues suggest that the treatment inhibits tumor stroma (α-SMA, Desmin and Hyluronic Acid) and induces changes in cell stiffness, as measured via Atomic Force Microscopy. This was accompanied by alteration of key cellular proteins of SHH signaling such as SHH, Gli-1, Gli-2, Sufu, and NFĸB-65 as indicated by Immunoblotting and Immunohistochemistry. These results suggest that SP-CUR has a great potential for future clinical use in the management of pancreatic cancer.

Abstract
BACKGROUND Osteochondral injuries represent a significant clinical problem requiring novel cell-based therapies to restore function of the damaged joint with the use of mesenchymal stromal cells (MSCs) leading research efforts. Pre-clinical studies are fundamental in translating such therapies; however, technologies to minimally invasively assess in vivo cell fate are currently limited. We investigate the potential of a MRI- (magnetic resonance imaging) and superparamagnetic iron oxide nanoparticle (SPION)-based technique to monitor cellular bio-distribution in an ovine osteochondral model of acute and chronic injuries. METHODS MSCs were isolated, expanded and labelled with Nanomag, a 250-nm SPION, and using a novel cell-penetrating technique, glycosaminoglycan-binding enhanced transduction (GET). MRI visibility thresholds, cellular toxicity and differentiation potential post-labelling were assessed in vitro. A single osteochondral defect was created in the medial femoral condyle in the left knee joint of each sheep with the contralateral joint serving as the control. Cells, either GET-Nanomag labelled or unlabelled, were delivered 1 week or 4.5 weeks later. Sheep were sacrificed 7 days post implantation and immediately MR imaged using a 0.2-T MRI scanner and validated on a 3-T MRI scanner prior to histological evaluation. RESULTS MRI data demonstrated a significant increase in MRI contrast as a result of GET-Nanomag labelling whilst cell viability, proliferation and differentiation capabilities were not affected. MRI results revealed evidence of implanted cells within the synovial joint of the injured leg of the chronic model only with no signs of cell localisation to the defect site in either model. This was validated histologically determining the location of implanted cells in the synovium. Evidence of engulfment of Nanomag-labelled cells by leukocytes is observed in the injured legs of the chronic model only. Finally, serum c-reactive protein (CRP) levels were measured by ELISA with no obvious increase in CRP levels observed as a result of P21-8R:Nanomag delivery. CONCLUSION This study has the potential to be a powerful translational tool with great implications in the clinical translation of stem cell-based therapies. Further, we have demonstrated the ability to obtain information linked to key biological events occurring post implantation, essential in designing therapies and selecting pre-clinical models.

Abstract
Mesenchymal stem cells (MSCs) that display homing and infiltration properties towards tumor cells are a promising cellular targeting vector for brain tumor therapy but are limited to local-regional delivery in current preclinical models. Here, we investigated whether placenta-derived MSCs (P-MSCs) are a superior cellular vector for systemic targeting of glioblastoma stem-like cells (GSCs), with an imaging modality to real-time monitor the trafficking P-MSCs to glioblastoma sites. Results demonstrated that P-MSCs had greater migratory activity towards GSCs and across blood-brain barrier compared with bone marrow-derived MSCs, and this activity was enhanced by hypoxia precondition. Chemokine ligand 5 was identified as a chemoattractant responsible for the glioblastoma tropism of P-MSCs. Polyethylene glycol-coated superparamagnetic iron oxide (PEG-SPIO) was synthesized for cellular labelling and imaging P-MSCs, displaying high cellular uptake and no cytotoxic effect on P-MSCs cell proliferation or stemness property. The homing effects of intravenously administered PEG-SPIO-labelled P-MSCs towards intracerebral GSCs were able to be detected in mice models through T2-weighted magnetic resonance imaging (MRI). This study suggests the possibility of innovative systemic P-MSC-based cell therapy for aggressive GSCs, developing a state-of-the-art theranostic technique for real-time tracking of therapeutic P-MSCs tumor infiltration through cellular MRI.

Abstract
Murine tumor models have played a fundamental role in the development of novel therapeutic interventions and are currently widely used in translational research. Specifically, strategies that aim at reducing inter-animal variability of tumor size in transplantable mouse tumor models are of particular importance. In our approach, we used magnetic nanoparticles to label and manipulate colon cancer cells for the improvement of the standard syngeneic subcutaneous mouse tumor model. Following subcutaneous injection on the scruff of the neck, magnetically-tagged implanted cancer cells were manipulated by applying an external magnetic field towards localized tumor formation. Our data provide evidence that this approach can facilitate the formation of localized tumors of similar shape, reducing thereby the tumor size's variability. For validating the proof-of-principle, a low-dose of 5-FU was administered in small animal groups as a representative anticancer therapy. Under these experimental conditions, the 5-FU-induced tumor growth inhibition was statistically significant only after the implementation of the proposed method. The presented approach is a promising strategy for studying accurately therapeutic interventions in subcutaneous experimental solid tumor models allowing for the detection of statistically significant differences between smaller experimental groups.

Abstract
There is an urgent need for 3D cell culture systems that avoid the oversimplifications and artifacts of conventional culture in 2D. However, 3D culture within the cavities of porous biomaterials or large 3D structures harboring high cell numbers is limited by the needs to nurture cells and to remove growth-limiting metabolites. To overcome the diffusion-limited transport of such soluble factors in 3D culture, mixing can be improved by pumping, stirring or shaking, but this in turn can lead to other problems. Using pumps typically requires custom-made accessories that are not compatible with conventional cell culture disposables, thus interfering with cell production processes. Stirring or shaking allows little control over movement of scaffolds in media. To overcome these limitations, magnetic, macroporous hydrogels that can be moved or positioned within media in conventional cell culture tubes in a contactless manner are presented. The cytocompatibility of the developed biomaterial and the applied magnetic fields are verified for human hematopoietic stem and progenitor cells (HSPCs). The potential of this technique for perfusing 3D cultures is demonstrated in a proof-of-principle study that shows that controlled contactless movement of cell-laden magnetic hydrogels in culture media can mimic the natural influence of differently perfused environments on HSPCs.

Abstract
Measuring iron content has practical clinical indications in the study of diseases such as Parkinson's disease, Huntington's disease, ferritinopathies and multiple sclerosis as well as in the quantification of iron content in microbleeds and oxygen saturation in veins. In this work, we review the basic concepts behind imaging iron using T2, T2*, T2', phase and quantitative susceptibility mapping in the human brain, liver and heart, followed by the applications of in vivo iron quantification in neurodegenerative diseases, iron tagged cells and ultra-small superparamagnetic iron oxide (USPIO) nanoparticles.

Abstract
The precise knowledge on various interactions of metal nanoparticles (NP) in a living organism is scarce. It is expected that metals can bind to nucleic acids, peptides and proteins (e.g. enzymes), and modify the functioning of vital cellular compartments after entering the organism. The predictive factors for quantitative nanostructure-activity relationship (QNAR) analysis could enhance efficient and harmless usage of nanoparticles (NPs) in the industry as well in the medicine. The studies value the composition of the NP corona determined by time, temperature and source of protein which has been found to implicate the physiological behaviour of NPs. One has largely been ignored: the NPs specific isoelectric point (IEP) and pH at the state of measurement. Herein, this study investigates the effect of pH and surface charge of six metal oxide (MeOx) NPs on time dependency of cytotoxicity. Several aspects of the characterization of ultrafine particles in the actual test system which is the most relevant for the interpretation of the toxicological data are referred: (i) the difference of pH in the room temperature and in the incubation conditions (ii) the difference of dispersions in MilliQ and complete cell media; (iii) the need to exemplify also the pH and isoelectric point when the hydrodynamic size is measured; (iv) the importance of time due to the time-dependent equilibration and changes of NPs corona. The surface charge determines the formation of corona and could be modified by pH. MeOx NPs without fully charge equilibrated corona might play the main role of MeOx NPs entering into the cell and consequently the time dependent manifestation of the cellular effect.

Abstract
Tendons are powerful 3D biomechanically structures combining a few cells in an intrincated and highly hierarchical niche environment. When tendon homeostasis is compromised, restoration of functionality upon injury is limited and requires alternatives to current augmentation or replacement strategies. Cell sheet technologies are a powerful tool for the fabrication of living extracellular-rich patches towards regeneration of tenotopic defects. Thus, we originally propose the development of magnetically responsive tenogenic patches through magnetic cell sheet (magCSs) technology that enable the remote control upon implantation of the tendon-mimicking constructs. A Tenomodulin positive (TNMD+) subpopulation of cells sorted from a crude population of human adipose stem cells (hASCs) previously identified as being prone to tenogenesis was selected for the magCSs patch construction. We investigated the stability, the cellular co-location of the iron oxide nanoparticles (MNPs), as well as the morphology and mechanical properties of the developed magCSs. Moreover, the expression of tendon markers and collagenous tendon-like matrix were further assessed under the actuation of an external magnetic field. Overall, this study confirms the potential to bioengineer tendon patches using a magnetic cell sheet construction with magnetic responsiveness, good mechanoelastic properties and a tenogenic prone stem cell population envisioning cell-based functional therapies towards tendon regeneration. STATEMENT OF SIGNIFICANCE The concept of magnetic force-based tissue engineering may assist the development of innovative solutions to treat tendon (or other tissues) disorders upon remote control of biological processes as cell migration or differentiation. Herein, we originally fabricated magnetic responsive cell sheets (magCSs) with a Tenomodulin positive subpopulation of adipose tissue derived stem cells identified to commit to the tenogenic lineage. To the best of authors knowledge, this is the first time a tendon oriented strategy resorting on magCSsis reported. Moreover, the promising role of tenogenic living constructs fabricated as magnetically responsive ECM-rich patches is highlighted, envisioning the stimulation of endogenous regenerative mechanisms. Altogether, these findings contribute to future stem cell studies and their translation toward tendon therapies.

Abstract
Magnetic hyperthermia, in which magnetic nanoparticles are introduced into tumors and exposed to an alternating magnetic field (AMF), appears to be promising since it can lead to increased life expectancy in patients. Its efficacy can be further improved by using biocompatible iron oxide magnetosome minerals with better crystallinity and magnetic properties compared with chemically synthesized nanoparticles (IONP - Iron Oxide Nanoparticles). To fabricate such minerals, magnetosomes are first isolated from MSR-1 magnetotactic bacteria, purified to remove potentially toxic organic bacterial residues and stabilized with poly-l-lysine (N-PLL), citric acid (N-CA), oleic acid (N-OA), or carboxy-methyl-dextran (N-CMD). The different coated nanoparticles appear to be composed of a cubo-octahedral mineral core surrounded by a coating of different thickness, composition, and charge, and to be organized in chains of various lengths. The in vitro anti-tumor and heating efficacies of these nanoparticles were examined by bringing them into contact with GL-261 glioblastoma cells and by applying an AMF. This led to a specific absorption rate of 89-196 W gFe -1, measured using an AMF of 198 kHz and 34-47 mT, and to percentages of tumor cell destruction due to the exposure of the nanoparticles to the AMF of 10 ± 3% to 43 ± 3% depending on the coating agent. These results show the potential of this protocol for the tumor treatment by magnetic hyperthermia.

Abstract
We report the development and optimisation of an assay for quantitating iron from iron oxide nanoparticles in biological matrices by using ferene-s, a chromogenic compound. The method is accurate, reliable and can be performed with basic equipment common to many laboratories making it convenient and inexpensive. The assay we have developed is suited for quantitation of iron in cell culture studies with iron oxide nanoparticles, which tend to manifest low levels of iron. The assay was validated with standard reference materials and with inductively coupled plasma-mass spectrometry (ICP-MS) to accurately measure iron concentrations ~1 × 10−6 g in about 1 × 106 cells (~1 × 10−12 g Fe per cell). The assay requires preparation and use of a working solution to which samples can be directly added without further processing. After overnight incubation, the absorbance can be measured with a standard UV/Vis spectrophotometer to provide iron concentration. Alternatively, for expedited processing, samples can be digested with concentrated nitric acid before addition to the working solution. Optimization studies demonstrated significant deviations accompany variable digestion times, highlighting the importance to ensure complete iron ion liberation from the nanoparticle or sample matrix to avoid underestimating iron concentration. When performed correctly, this method yields reliable iron ion concentration measurements to ~2 × 10−6 M (1 × 10−7 g/ml sample).

Abstract
Heavy metals are found naturally on Earth and exposure to them in the living environment is increasing as a consequence of human activity. The toxicity of six different metal oxide nanoparticles (NP) at different points in time was compared using resazurin assay. After incubating Caco2 and A549 cells with 100 μg/mL of Sb2O3, Mn3O4 and TiO2 nanoparticles (NPs) for 24 h no toxic effects were observed while Co3O4 and ZnO NPs had moderate effects and CuO NPs were toxic below 100 μg/mL (24 h EC25 = 11 for A549 and 71 μg/mL for Caco2). The long-term monitoring (up to 9 days) of cells to NPs revealed that the toxic effects of Mn3O4 and Sb2O3 NPs remarkably increased over time. The 9 day EC50 values for Sb2O3 NPs were 22 and 48 μg/mL for A549 and Caco2 cells; and for Mn3O4 NPs were 47 and 29 μg/mL for A549 and Caco2 cells, respectively. In general, the sensitivity of the cell lines in the resazurin assay was comparable. Trans epithelial electrical resistance (TEER) measurements were performed for both cell types exposed to Co3O4, Sb2O3 and CuO NPs. In TEER assay, the Caco2 cells were more susceptible to the toxic effects of these NPs than A549 cells, where the most toxic NPs were the Sb2O3 NPs: the permeability of the Caco2 cell layer exposed to 10 μg/mL Sb2O3 NPs already increased after 24 h of exposure.

Abstract
AIM We aimed to analyze the suitability of nanoparticles (M4E) for safe human mesenchymal stem cell (hMSC) labeling and determined cell labeling maintenance in 2D and 3D culture. MATERIALS & METHODS We investigated cell-particle interaction and the particles' impact on cell viability, growth and proliferation. We analyzed cell labeling maintenance in 2D and 3D culture invasively and noninvasively. RESULTS M4E do not affect cell viability, growth and proliferation and do not cause chromosomal aberrations. Cell labeling maintenance is up to five-times higher in 3D conditions compared with 2D culture. CONCLUSION M4E allow safe hMSC labeling and noninvasive identification. Our hMSC-loaded, 3D tissue-engineered construct could serve as a graft for regenerative therapies, in which M4E-labeled hMSCs can migrate to their target.

Abstract
In vivo cell tracking has emerged as a much sought after tool for design and monitoring of cell-based treatment strategies. Various techniques are available for pre-clinical animal studies, from which much has been learned and still can be learned. However, there is also a need for clinically translatable techniques. Central to in vivo cell imaging is labelling of cells with agents that can give rise to signals in vivo, that can be detected and measured non-invasively. The current imaging technology of choice for clinical translation is MRI in combination with labelling of cells with magnetic agents. The main challenge encountered during the cell labelling procedure is to efficiently incorporate the label into the cell, such that the labelled cells can be imaged at high sensitivity for prolonged periods of time, without the labelling process affecting the functionality of the cells. In this respect, nanoparticles offer attractive features since their structure and chemical properties can be modified to facilitate cellular incorporation and because they can carry a high payload of the relevant label into cells. While these technologies have already been applied in clinical trials and have increased the understanding of cell-based therapy mechanism, many challenges are still faced.

Abstract
Cell labeling and tracking are becoming increasingly important areas within the field of stem cell transplantation. The ability to track the migration and distribution of implanted cells is critical to understanding the beneficial effects and mechanisms of stem cell therapy. The present study investigated the effects of amine-surface-modified superparamagnetic iron oxide (SPIO) nanoparticles on the biological properties of human adipose tissue-derived stem cells (hADSCs). Monodisperse hydrophobic magnetite (Fe3 O4 ) nanoparticles were prepared using silicon and surface-modified with amine coating. Cell viability, proliferation, differentiation potential, and surface marker expression were evaluated. The magnetic particles (10-18 nm) displayed high labeling efficiency and stability in hADSCs. SPIO-labeled cells produced a hypointense signal and were effectively visualized by MRI for up to 21 days. The results of MTT proliferation assays and flow cytometry analysis demonstrated that SPIOs were biocompatible, viz. the labeling process did not cause cell death or apoptosis and had no side effects on cell proliferation. In vivo experiments showed that the magnetic particles did not affect liver and kidney function. The successful and stable labeling of hADSCs combined with efficient magnetic tropism demonstrates that SPIOs are promising candidates for hADSC tracking in hADSC-based cell therapy applications.

Assessment of morphological and functional changes in organs of rats after intramuscular introduction of iron nanoparticles and their agglomerates. BIOMED RESEARCH INTERNATIONAL 2015; 2015:243173. [PMID: 25789310 PMCID: PMC4350962 DOI: 10.1155/2015/243173] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/12/2014] [Revised: 01/30/2015] [Accepted: 01/30/2015] [Indexed: 12/21/2022]
Abstract
The research was performed on male Wistar rats based on assumptions that new microelement preparations containing metal nanoparticles and their agglomerates had potential. Morphological and functional changes in tissues in the injection site and dynamics of chemical element metabolism (25 indicators) in body were assessed after repeated intramuscular injections (total, 7) with preparation containing agglomerate of iron nanoparticles. As a result, iron depot was formed in myosymplasts of injection sites. The quantity of muscle fibers having positive Perls' stain increased with increasing number of injections. However, the concentration of the most chemical elements and iron significantly decreased in the whole skeletal muscle system (injection sites are not included). Consequently, it increased up to the control level after the sixth and the seventh injections. Among the studied organs (liver, kidneys, and spleen), Caspase-3 expression was revealed only in spleen. The expression had a direct dependence on the number of injections. Processes of iron elimination from preparation containing nanoparticles and their agglomerates had different intensity.
