Surface marker expression of mASC (A) and hASC (B). IC-isotype controls, AS- antigen-specific antibodies. As expected, the majority of mASCs expressed the surface antigen of mesenchymal stem cells Sca-1, and was negative for the hematopoietic stem cell marker (CD45) and endothelial marker (CD31). The majority of hASC expressed stromal markers CD13, CD73, CD90, and CD105, and was negative for CD31, CD45.
