Abstract
The current study aimed to investigate adipose tissue-derived stem cells (ADSCs) in vivo by multimodality imaging following implantation for cellular therapy. The biological characteristics of ADSCs co-labeled with Molday ION Rhodamine B™ (MIRB) and green fluorescent protein (GFP) were studied in vitro. Following rat ADSC isolation and culture, a combined labeling strategy for ADSCs based on genetic modification of the reporter gene GFP with lentiviral vector expression enhancement and physical MIRB labeling was performed. Cell viability, proliferation, membrane-bound antigens and multiple differentiation ability were compared between the labeled and unlabeled ADSCs. The ADSCs were successfully labeled with GFP and MIRB, showing various fluorescent colors for marker identification. The fluorescence emitted by the GFP protein was sustained and exhibited stable expression, while MIRB fluorescence decreased with time. Compared with the unlabeled ADSCs, no significant differences were detected in cell viability, proliferation, membrane-bound antigens and multiple differentiation ability in the co-labeled samples (P>0.05). No significant effects on the biophysical properties of ADSCs were observed following co-labeling with lentiviral vectors encoding the gene for emerald green fluorescent protein and MIRB. The ADSCs were able to be efficiently tracked in vitro and in vivo by multimodality imaging thus, the co-labeling approach provides a novel strategy for therapeutic gene studies.

Abstract
BACKGROUND AIMS Adipose-derived stem cells (ADSCs) have shown great promise in the regenerative repair of injured peripheral nerves. Magnetic resonance imaging (MRI) has provided attractive advantages in tracking superparamagnetic iron oxide nanoparticle (SPION)-labeled cells and evaluating their fate after cell transplantation. This study investigated the feasibility of the use of MRI to noninvasively track ADSCs repair of peripheral nerve injury in vivo. METHODS Green fluorescent protein (GFP)-expressing ADSCs were isolated, expanded, differentiated into an SC-like phenotype (GFP-dADSCs) at early passages and subsequently labeled with SPIONs. The morphological and functional properties of the GFP-dADSCs were assessed through the use of immunohistochemistry. The intracellular stability, proliferation and viability of the labeled cells were evaluated in vitro. Through the use of a microsurgical procedure, the labeled cells were then seeded into sciatic nerve conduits in C57/BL6 mice to repair a 1-cm sciatic nerve gap. A clinical 3-T MRI was performed to investigate the GFP-dADSCs in vitro and the transplanted GFP-dADSCs inside the sciatic nerve conduits in vivo. RESULTS The GFP-dADSCs were efficiently labeled with SPIONs, without affecting their viability and proliferation. The labeled cells implanted into the mice sciatic nerve conduit exhibited a significant increase in axonal regeneration compared with the empty conduit and could be detected by MRI. Fluorescent microscopic examination, histological analysis and immunohistochemistry confirmed the axon regeneration and MRI results. CONCLUSIONS These data will elucidate the neuroplasticity of ADSCs and provide a new protocol for in vivo tracking of stem cells that are seeded to repair injured peripheral nerves.

Abstract
Objective We previously isolated fetal liver stem/progenitor cells (FLSPCs), but there is an urgent need to properly amplify FLSPCs, effectively induce FLSPCs differentiation, and steadily trace FLSPCs for in vivo therapeutic investigation. Methods FLSPCs were maintained in vitro as adherent culture or soft agar culture for large-scale amplification. To direct the differentiation of FLSPCs into hepatocytes, FLSPCs were randomly divided into four groups: control, 1% DMSO-treated, 20 ng/ml HGF-treated and 1% DMSO+20 ng/ml HGF-treated. To trace FLSPCs, the GFP gene was introduced into FLSPCs by liposome-mediated transfection. Results For amplifying FLSPCs, the soft agar culture were more suitable than the adherent culture, because the soft agar culture obtained more homogeneous cells. These cells were with high nuclear:cytoplasmic ratio, few cell organelles, high expression of CD90.1 and CD49f, and strong alkaline phosphatase staining. For inducing FLSPCs differentiation, treatment with HGF+DMSO was most effective (P<0.05), which was strongly supported by the typical morphological change and the significant decrease of OV-6 positive cells (P<0.01). In addition, the time of indocyanine green elimination, the percentage of glycogen synthetic cells, and the expressions of ALB, G-6-P, CK-8, CK-18 and CYP450-3A1 in HGF+DMSO-treated group were higher than in any other group. For tracing FLSPCs, after the selection of stable FLSPC transfectants, GFP expression continued over successive generations. Conclusions FLSPCs can properly self-renew in soft agar culture and effectively differentiate into hepatocyte-like cells by HGF+DMSO induction, and they can be reliably traced by GFP expression.

Abstract
Background Stem cell therapy has shown great promise for regenerative repair of injured or diseased tissues. Adipose-derived stem cells (ADSCs) have become increasingly attractive candidates for cellular therapy. Magnetic resonance imaging has been proven to be effective in tracking magnetic-labeled cells and evaluating their clinical relevance after cell transplantation. This study investigated the feasibility of imaging green fluorescent protein-expressing ADSCs (GFP-ADSCs) labeled with superparamagnetic iron oxide particles, and tracked them in vivo with noninvasive magnetic resonance imaging after cell transplantation in a model of mouse carotid artery injury. Methods GFP-ADSCs were isolated from the adipose tissues of GFP mice and labeled with superparamagnetic iron oxide particles. Intracellular stability, proliferation, and viability of the labeled cells were evaluated in vitro. Next, the cells were transplanted into a mouse carotid artery injury model. Clinical 3 T magnetic resonance imaging was performed immediately before and 1, 3, 7, 14, 21, and 30 days after cell transplantation. Prussian blue staining and histological analysis were performed 7 and 30 days after transplantation. Results GFP-ADSCs were found to be efficiently labeled with superparamagnetic iron oxide particles, with no effect on viability and proliferation. Homing of the labeled cells into the injured carotid artery tissue could be monitored by magnetic resonance imaging. Conclusion Magnetically labeled ADSCs with expression of GFP can home into sites of vascular injury, and may provide new insights into understanding of cell-based therapy for cardiovascular lesions.

PLoS One 2012; 7:e31137. [PMID: 22363566 PMCID: PMC3281926 DOI: 10.1371/journal.pone.0031137] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2011] [Accepted: 01/03/2012] [Indexed: 11/18/2022] Open
Abstract
Background This study was to validate the feasibility of using clinical 3.0T MRI to monitor the migration of autotransplanted bone marrow (BM)-derived stem-progenitor cells (SPC) to the injured arteries of near-human sized swine for potential cell-based arterial repair. Methodology The study was divided into two phases. For in vitro evaluation, BM cells were extracted from the iliac crests of 13 domestic pigs and then labeled with a T2 contrast agent, Feridex, and/or a fluorescent tissue marker, PKH26. The viability, the proliferation efficiency and the efficacies of Feridex and/or PKH26 labeling were determined. For in vivo validation, the 13 pigs underwent endovascular balloon-mediated intimal damages of the iliofemoral arteries. The labeled or un-labeled BM cells were autotransplanted back to the same pig from which the BM cells were extracted. Approximately three weeks post-cell transplantation, 3.0T T2-weighted MRI was performed to detect Feridex-created signal voids of the transplanted BM cells in the injured iliofemoral arteries, which was confirmed by subsequent histologic correlation. Principal Findings Of the in vitro study, the viability of dual-labeled BM cells was 95–98%. The proliferation efficiencies of dual-labeled BM cells were not significantly different compared to those of non-labeled cells. The efficacies of Feridex- and PKH26 labeling were 90% and 100%, respectively. Of the in vivo study, 3.0T MRI detected the auto-transplanted BM cells migrated to the injured arteries, which was confirmed by histologic examinations. Conclusion This study demonstrates the capability of using clinical 3.0T MRI to monitor the auto-transplantation of BM cells that migrate to the injured arteries of large animals, which may provide a useful MRI technique to monitor cell-based arterial repair.

Sun J, Li X, Feng H, Gu H, Blair T, Li J, Soriano S, Meng Y, Zhang F, Feng Q, Yang X. Magnetic resonance imaging of bone marrow cell-mediated interleukin-10 gene therapy of atherosclerosis. PLoS One 2011; 6:e24529. [PMID: 21915349 PMCID: PMC3168522 DOI: 10.1371/journal.pone.0024529] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2011] [Accepted: 08/12/2011] [Indexed: 11/23/2022] Open
Abstract
Background A characteristic feature of atherosclerosis is its diffuse involvement of arteries across the entire human body. Bone marrow cells (BMC) can be simultaneously transferred with therapeutic genes and magnetic resonance (MR) contrast agents prior to their transplantation. Via systemic transplantation, these dual-transferred BMCs can circulate through the entire body and thus function as vehicles to carry genes/contrast agents to multiple atherosclerosis. This study was to evaluate the feasibility of using in vivo MR imaging (MRI) to monitor BMC-mediated interleukin-10 (IL-10) gene therapy of atherosclerosis. Methodology For in vitro confirmation, donor mouse BMCs were transduced by IL-10/lentivirus, and then labeled with a T2-MR contrast agent (Feridex). For in vivo validation, atherosclerotic apoE−/− mice were intravenously transplanted with IL-10/Feridex-BMCs (Group I, n = 5) and Feridex-BMCs (Group II, n = 5), compared to controls without BMC transplantation (Group III, n = 5). The cell migration to aortic atherosclerotic lesions was monitored in vivo using 3.0T MRI with subsequent histology correlation. To evaluate the therapeutic effect of BMC-mediated IL-10 gene therapy, we statistically compared the normalized wall indexes (NWI) of ascending aortas amongst different mouse groups with various treatments. Principal Findings Of in vitro experiments, simultaneous IL-10 transduction and Feridex labeling of BMCs were successfully achieved, with high cell viability and cell labeling efficiency, as well as IL-10 expression efficiency (≥90%). Of in vivo experiments, MRI of animal groups I and II showed signal voids within the aortic walls due to Feridex-created artifacts from the migrated BMCs in the atherosclerotic plaques, which were confirmed by histology. Histological quantification showed that the mean NWI of group I was significantly lower than those of group II and group III (P<0.05). Conclusion This study has confirmed the possibility of using MRI to track, in vivo, IL-10/Feridex-BMCs recruited to atherosclerotic lesions, where IL-10 genes function to prevent the progression of atherosclerosis.
