Typical characteristics of huMSCs. (a,b) HuMSC morphology was polygonal, swirling and fibroblast-like (×100 magnification). (b) Wright staining. (c) TEM showed that the connection between huMSCs primarily depended on microvilli contact, whilst tight junctions were occasionally visible. (d) HuMSC expression of CD29, CD44, CD73, CD90, CD105 and HLA-ABC was visibly high. However, the expression CD31, CD34, CD45, CD133, CD271 and HLA-DR was negative; n = 5.
