Figure 1 (A) Human MSC are spindle-shaped, large flat cells. Original magnification ×40. (B) Cell death was determined by fluorescence-activated cell sorting analysis using 7-AAD. (C) MSC do not express hematopoietic markers CD34 and CD45. (D) Cell-surface Ag of CD73 and CD105 on MSC.

Figure 2 (A) Cell-surface Ag of NG2 and CD105 on MSC. (B) NG2 is not expressed on uncultured BM cells. (C) NG2 has a similar expression rate compared with the other markers of MSC. (D) Negative control of Oil Red O staining of human MSC culture before adipogenic treatment. Original magnification ×40. (E) To evaluate MSC multipotentiality. Oil Red O staining of human MSC culture after adipogenic treatment, showing lipid droplets. Original magnification ×40. (F) Alizarin Red S staining of human MSC culture after osteogenic induction, showing calcium phosphate deposits. Original magnification ×40.
