PMA pretreatment increases initial attachment of ADSCs to culture substrate. a Representative images of ADSCs attached to culture substrate with or without 4 h of PMA pretreatment. Scale bar = 200 μm. b Number of ADSCs attached to culture substrate was counted (per field). The quantitative data were expressed as the mean ± S.E.M of at least 3 independent experiments. *p < 0.05
