Human mesenchymal stem cells derived from adipose tissue (hADMSCs) are a desirable candidate in regenerative medicine. hADMSCs secrete growth factors, cytokines, and chemokines and also express various receptors that are important in cell activation, differentiation, and migration to injured tissue. We showed that the expression level of chemokine receptor CXCR6 was significantly increased by ~2.5-fold in adipogenic-differentiated cells (Ad), but not in osteogenic-differentiated cells (Os) when compared with hADMSCs. However, regulation of CXCR6 expression on hADMSCs by using lentiviral particles did not affect the differentiation potential of hADMSCs. Increased expression of CXCR6 on Ad was mediated by both receptor recycling, which was in turn regulated by secretion of CXCL16, and de novo synthesis. The level of soluble CXCL16 was highly increased in both Ad and Os in particular, which inversely correlates with the expression on a transmembrane-bound form of CXCL16 that is cleaved by disintegrin and metalloproteinase. We concluded that the expression of CXCR6 is regulated by receptor degradation or recycling when it is internalized by interaction with CXCL16 and by de novo synthesis of CXCR6. Overall, our study may provide an insight into the molecular mechanisms of the CXCR6 reciprocally expressed on differentiated cells from hADMSCs.

ABSTRACT The adipose tissue is a reliable source of Mesenchymal stem cells (MSCs) showing a higher plasticity and transdifferentiation potential into multilineage cells. In the present study, adipose tissue-derived mesenchymal stem cells (AT-MSCs) were isolated from mice omentum and epididymis fat depots. The AT-MSCs were initially compared based on stem cell surface markers and on the mesodermal trilineage differentiation potential. Additionally, AT-MSCs, from both sources, were cultured with differentiation media containing retinoic acid (RA) and/or testicular cell-conditioned medium (TCC). The AT-MSCs expressed mesenchymal surface markers and differentiated into adipogenic, chondrogenic and osteogenic lineages. Only omentum-derived AT-MSCs expressed one important gene marker related to male germ cell lineages, after the differentiation treatment with RA. These findings reaffirm the importance of adipose tissue as a source of multipotent stromal-stem cells, as well as, MSCs source regarding differentiation purpose.

Abstract Back ground Adipose tissue derived mesenchymal stem cells (ASCs) have unique potential for regenerative cell therapies. However, during ex-vivo cultivation, they undergo considerable quality loss regarding their phenotypic properties, stemness genes expression and differentiation potential. Recent studies reported that the loss of stemness properties of MSCs is a result of chromatin histone deacetylations through in-vitro cultivation. The present work aimed to study the effect of Trapoxin A (TPX) as a histone deacetylase inhibitor (HDACi) on overall stemness properties of ASCs. Methods First, the effects of TPX treatments on ASCs viability and proliferation were evaluated using MTT assay. Second, the desired doses of TPX supporting ASCs proliferation were determined and the lack of their negative effects was confirmed by DAPI staining. In addition, the influence of TPX on cell cycle of ASCs and the mRNA levels of stemness genes were measured by flowcytometry and qPCR, respectively. Finally, the effect of TPX treatment on osteogenic potential of ASCs was studied. Results The results indicated that short time TPX treatment (nM concentrations) caused stimulation of proliferation and considerable percentage of ASCs entered to S-phase of cell cycle (p<0.05). Moreover, the findings demonstrated significant up-regulation of stemness markers genes (Oct-4, Sox-2, Nanog, TERT, Klf-4, Rex-1) (p<0.05) and enhanced osteogenic differentiation potential of ASC after TPX treatment. Conclusion The addition of low dose of TPX to the expansion medium could possibly enhance the stemness properties and prevent the quality decline of ex-vivo cultured ASCs.

Aim. The effects of cryopreservation on adipose tissue-derived mesenchymal stem cells are not clearly documented, as there is a growing body of evidence about the importance of adipose-derived mesenchymal stem cells for regenerative therapies. The aim of this study was to analyze human adipose tissue-derived mesenchymal stem cells phenotypic expression (CD34, CD45, CD73, CD90, CD105, and CD49d), colony forming unit ability, viability, and differentiation potential before and after cryopreservation.Materials and Methods. 12 samples of the adipose tissue were collected from a healthy donor using the liposuction technique. The cell isolation was performed by enzymatic digestion and then the cells were cultured up to passage 2. Before and after cryopreservation the immunophenotype, cellular viability analysis by flow cytometer, colony forming units ability, differentiation potential into adipocytes and osteoblasts as demonstrated by Oil Red O and Alizarin Red staining, respectively.Results. The immunophenotypic markers expression was largely preserved, and their multipotency was maintained. However, after cryopreservation, the cells decreasedα4-integrin expression (CD49d), cell viability, and number of colony forming units.Conclusions. These findings suggest that ADMSC transplanted after cryopreservation might compromise the retention of transplanted cells in the host tissue. Therefore, further studies are warranted to standardize protocols related to cryopreservation to attain full benefits of stem cell therapy.
