Isolation and characterization of PDLSCs. (A) Isolation of PDLSCs. Spindle-shaped cells at passage 0 and 3; (B) Flow cytometric analyses of PDLSCs. They were positive for MSCs markers CD29, CD73, CD90 and CD105, while negative for hematopoietic markers CD34 and CD45. (C) Live/Dead staining images of PDLSCs (Cell) and PDLSCs for cell injection (I-Cell). (D) Quantitative analysis of fluorescent intensity at 24 h. (E) Cell viability by CCK-8 at 24. n = 3. *p < 0.05
