Effects of BMP-2 and TGF-β1 on the expression and phosphorylation of Cx43 protein. Western analysis of Cx43 protein expression for control, BMP-2, and TGF-β1 groups after treatment for 24 h (top panel) and 48 h (bottom panel) in the absence (-) or presence (+) of ALP. Experiments suggest that 43 kD and 46 kD bands represent the unphosphorylated and phosphorylated forms of Cx43, respectively.
