Immunophenotype of cultured DPSCs. Studies based on immunoperoxidase reactivity were performed on first passage cultures of DSPCs. Representative staining patterns are shown for: integrin β1 (A); CD44 (B); collagen type I (C); collagen type III (D); fibroblast growth factor-2 (E); osteonectin (F); osteocalcin (G); MUC-18 (CD146) (H); α-smooth muscle actin (I); osteopontin (J); and vascular cell adhesion molecule 1 (K). Endogenous alkaline phosphatase activity is shown in L.
