Fig. 1. The MSC and NP cell surface markers expression were analysis by flow cytometry after 72 h treatment with UCMSCs-CM. (A) MSC positive surface markers, (B) MSC negative surface markers, (C) NP cell surface marker CD24. The data are presented as the means±SD, n=3. *p<0.05, compare with D-NPSCs group. UCMSCs were positive for CD29, CD44, CD73, CD90 and CD105 at rates greater than 95%. For D-NPSCs, the expression of CD29, and CD105 showed interindividual variability but all at rates lower than 95%, however, CD29 and CD105 in CM group were at rates greater than 95%, and the CM group revealed a very similar expression pattern of surface markers with UCMSCs group; Cells in all three groups were negative for the hematopoietic stem cell surface markers CD11b, CD14, CD34, CD45 and HLA-DR. Cells in all three groups expressed CD24 at low rates, while the rate in D-NPSCs significantly higher than that in both CM group and UCMSCs group.
