Effect of BMP2 or BMP4 supplementation on CT1 cell survival. CT1 cells were supplemented with various concentrations of BMP2 (left panel) or BMP4 (right panel) for 48 h, then viable cell numbers were quantified by examining the metabolism a tetrazolium compound (MTS) into a colored formazon product visible at 490 nm (n = 4 replicate studies for each BMP). Different superscripts within each BMP treatment denote differences (P < 0.05).
