Figure 3From: Bone morphogenetic protein-2 (BMP-2) and transforming growth factor-β1 (TGF-β1) alter connexin 43 phosphorylation in MC3T3-E1 CellsDensitometric analysis of Cx43 expression. Total Cx43 protein expression (left) and the ratio of the 43 kD: 46 kD bands (right) normalized to control levels. Values are mean ± S.D. of 3 separate experiments with control set at 100% (* p < 0.05 compared to control).Back to article page
