Comparison of cell surface proteins between ACL- and bone marrow (BM)-derived MSCs. Cell surface protein expression in ACL-MSCs (CD73+/90+) and BM-MSCs (CD90+/271+) before (a) and after culture (b). (c) Principal component analysis of four types of cells. ACL-derived CD73+/90+ MSCs: fresh (blue, circle) and cultured (blue, square); BM-derived CD90+/271+ MSCs: fresh (red, circle) and cultured (red, square).
