Synthesis, storage and regulated secretion of tissue-type plasminogen activator by cultured rat heart endothelial cells

The synthesis, storage and regulated secretion (acute release) of tissue-type plasminogen activator (tPA) were studied in cultured rat heart endothelial (RHE) cells. In this study, special attention was paid to the correspondence between tPA metabolism in RHE cells in vitro and tPA metabolism in rats in vivo. RHE cells synthetized tPA, as shown...
