Cell morphology and surface antigens before and after malignant transformation. Compared with MSCs, cells that underwent malignant induction (MTMSCs) became small and demonstrated a spindle-like shape (a). Flow cytometric analysis showed that the expression of the MSC-specific cell surface antigen CD90 was significantly decreased (P<0.01), but that of CD45 was moderately increased after malignant transformation (b)
