1975年,LaBrecque等[1]从断乳大鼠肝脏经超离心提取到一种物质,能专一刺激肝细胞DNA合成及再生,称为“肝源性肝细胞刺激(HepaticStimulatorSubstance,HSS)”。以后,多位学者分别在狗、猪、兔的再生肝中提取到了这种物质[2~4]。HSS是一种高度带负电的蛋白多肽Mw12~18k。H
In 1975, LaBrecque et al [1] extracted a substance from the liver of weanling rats by ultracentrifugation and specifically stimulated DNA synthesis and regeneration of hepatocytes, which is called “HepaticStimulatorSubstance (HSS) ”. Later, many scholars extracted this material from the regenerating liver of dogs, pigs and rabbits respectively [2-4]. HSS is a highly negatively charged protein polypeptide Mw12 ~ 18k. H
