The characterization analysis of UCMSC^S&XFM−CD and UCMSC^SCM. A Morphology characteristics of UCMSC^S&XFM−CD and UCMSC^SCM. Scale bar = 100 μm. B Flow cytometry revealed that UCMSC^S&XFM−CD and UCMSC^SCM showed high expression of CD29, CD44, CD73, CD90 and CD105, but lacked expression of CD14, CD19, CD34, CD45 and HLA-DR surface antigens. C Representative images of osteogenic, chondrogenic, and adipogenic differentiation of UCMSC^S&XFM−CD and UCMSC^SCM after specific inductions and staining. Scale bars = 100 μm
