There are various types of adipose tissue in the human body, and their morphology is known to be closely related to cell function and metabolism. However, the functional differences among the mesenchymal stromal cells (MSCs) of different abdominal adipose tissues have not been clearly elucidated.MethodsMSCs were isolated from different abdominal adipose tissues according to their regional distribution and included superficial subcutaneous, deep subcutaneous, omentum, mesentery and retroperitoneal MSCs. The immunophenotype, proliferative ability and angiogenic function of these MSCs were compared based on flow cytometry analysis, CCK-8 proliferation, in vitro differentiation, tubule formation and in vivo plug assay.ResultsThe plastic adherence, cell morphology and general immunophenotype are similar among the MSCs. However, subcutaneous adipose tissue–derived MSCs have a faster growth rate and a higher level of CD146 expression than the other MSCs. Moreover, according to the fluorescence-activated cell sorting (FACS) enrichment procedure, the expression level of CD146 is positively related to the growth rate and angiogenic capability of MSCs.DiscussionMSCs in adipose tissue showed slightly different characteristics depending on their location of origin, and they possessed different angiogenic abilities that were mediated by the expression of CD146. This study provides evidence that subcutaneous adipose tissue is the most appropriate source of MSCs for therapeutic cell transplantation in vascular disease.
