As the signals required for cardiomyocyte differentiation and functional regulation are complex and only partly understood, the mechanisms prompting the differentiation and specification of pluripotential embryonic stem (ES) cells into cardiomyocytes remain unclear. We hypothesized that a combined technology system, cocultured with a visceral endoderm (VE)(More)
This study aimed to investigate whether nitric oxide (NO) could inhibit the elevated endothelin-1 (ET-1) gene expression by pulmonary artery endothelial cells or smooth muscle cells in chronically hypoxic rats by use of in situ hybridization. Male Wistar rats (n = 40) were randomly divided into 1-week hypoxia group, 1-week hypoxia with L-arginine (L-arg)(More)
