1975年Labrccquc 从断乳大鼠的肝脏提取到一种能促进肝细胞DNA 合成的物质,命名为肝细胞再生刺激因子(hepatic stimulator substance,HSS)。1988年以后,我国多个单位先后从断乳大鼠、乳猪、小牛和人胎肝细胞浆中提取出具有刺激肝细胞DNA 合成、促进肝细胞再生的小分子多肽物质。分别命名为肝细胞 1975 Labrccquc extracted from the liver of weanling rats to promote a kind of liver cell DNA synthesis of the material, named as hepatic stimulator stimulator (hepatic stimulator substance, HSS). Since 1988, many units in our country have successively extracted small molecule peptides from hepatocyte cytoplasm of weanling rats, suckling pigs, calves and human fetuses to stimulate DNA synthesis of hepatocytes and promote hepatocyte regeneration. Named hepatocytes separately
