Figure 4. BMP-2 stimulated HOXA10 and LIF expression in LCM treated ESC: Effect of transfection with mutant TGF-β receptor.
BMP-2 stimulated expression of HOXA10 and LIF was examined in LCM exposed ESC that had been transfected with mutant TGF-β Type II receptor or vector control. A: BMP-2 stimulated HOXA10 expression. BMP-2 stimulated HOXA10 expression was repressed in LCM exposed ESC that had been transfected with vector control plasmid, compared to non LCM exposed controls (0.33 fold, p<0.05). BMP-2 stimulated HOXA10 expression was not significantly changed, compared to non LCM exposed control ESC, when ESC had been transfected with mutant TGF-β Type II receptor prior to LCM exposure. B: BMP-2 stimulated LIF expression. BMP-2 stimulated LIF expression was repressed LCM exposed ESC that had been transfected with vector control plasmid, compared to non LCM exposed control ESC (0.64 fold, p<0.05). BMP-2 stimulated LIF expression was significantly increased, compared to non LCM exposed control ESC, when ESC had been transfected with mutant TGF-β Type II receptor prior to LCM exposure (1.57 fold, p<0.05).
