Figure 4

Effect of TNF-α and LPS on ET-1 release by endocardial endothelial cells. The values are mean ± SD (n = 6;*p < 0.01). Control-CM = Conditioned medium from untreated endocardial endothelial cells, TNF-CM = Conditioned medium from endocardial endothelial cells treated with TNF-α, LPS-CM = Conditioned medium from endocardial endothelial cells treated with LPS. 'n' is the number of times each experiment was done.
