“…However, currently, there is no specific marker or a combination of markers able to identify MSCs. Hence, the isolation of MSCs also depends on biologi-cal characteristics, such as colony-forming ability, fibroblast-like morphology (these cells are also known as colony-forming unit fibroblasts -CFU-Fs), plastic adherence, proliferative ability, and self-renewal and multi-differentiation potential 4 . Despite the lack of specific markers, MSCs often express STRO-1, CD44, CD73, CD90, and CD105, and are negative for CD31, CD34, CD45, CD80, CD86, and HLA-DR 5,6 .…”
