Hepatocytes and hepatic stellate cells play important roles in retinoid uptake, storage, mobilization and metabolism. Hepatic stellate cells represent only 5-7% of the total cells present in the liver. Isolation of primary stellate cells is thus time-consuming and often accompanied by low yields and considerable lot-to-lot variations. HSC-T6 Rat Hepatic Stellate Cell Line is an immortalized line isolated from SV40 large T-antigen transformed primary stellate cells of male Sprague-Dawley retired breeder rats. HSC-T6 Rat Hepatic Stellate Cell line is a useful model for the study of hepatic retinoid storage and metabolism.
