Abstract

Tube formation assay is the most widely used method as a vasculogenesis/ angiogenesis test in vitro. Mesenchymal stem cells (MSCs) are multipotent adult cells. The paracrine effect of MSCs on neovascularization is well known. In general, MSCs do not express CD34 hematopoietic surface marker, but according to some experts, bone marrow mesenchymal stem cells (BM-MSCs) express CD34 in vivo and lose their expression when they are cultured in vitro, while adipose-derived stem cells (ASCs) still have CD34 expression in the early passages when cultured in vitro. BM-MSCs are the most widely used MSC, but ASCs are also used in stem cell therapy and tissue engineering for angiogenesis purposes. Until now, the potential of vasculogenesis between ASCs and BM-MSCs is still unclear. Expression of CD34 is also unknown whether affecting the quality of tube formation. This study wanted to compare the potential of vasculogenesis between ASC and BM-MSCs through tube formation test and CD34 expression.Measurements of vasculogenesis quality showed higher tube length, number of loopsand mean number of branch points on BM-MSC. Both BM-MSCs and ASCs showed low CD34 levels.BM-MSCs showed better tube formation ability compared with ASCs. No association was found between CD34 levels and MSC vasculogenesis capability.
