The effect of various growth factors and cytokines on wound healing potential of passage 2 and passage 4 of PA-MSCs and CD271-MSCs 12 h after the assay initiation. a The effect of GFs/cytokines on potential of passage 2 PA-MSCs in wound closure. b The effect of GFs/cytokines on potential of passage 4 PA-MSCs in wound closure. c The effect of GFs/cytokines on potential of passage 2 CD271-MSCs in wound closure. d The effect of GFs/cytokines on potential of passage 4 CD271-MSCs in wound closure. The effects of EGF (1 ng/ml), TGF-β (5 ng/ml), HGF (5 ng/ml), FGF-2 (20 ng/ml), SDF-1α (20 ng/ml), PDGF-BB (20 ng/ml), MCP-1 (20 ng/ml), IL-8 (20 ng/ml) and IL-6 (10 ng/ml) on wound closure were examined using CytoSelect™ 24-well Wound Healing Assay. Significant changes were assessed by using unpaired t test. Data are represented as mean ± SD of at least n = 2
