肝再生增强因子 (ＡＬＲ)是Ｈａｇｉｙａ等〔1〕1 994年从新生大鼠肝组织中克隆的一种理化性质与肝刺激物 (ＨＳＳ)相似的促肝细胞增殖因子。新近 ,我国学者克隆了大鼠ＡＬＲ的人类同源分子〔2〕,并通过构建原核表达载体 ,获高效表达菌株 ,进而获得重组ｈＡＬＲ。初步研究表明
Liver regeneration augmentation factor (ALR) is Hagiya et al 〔1〕 1994 cloned from newborn rat liver tissue of a physical and chemical properties and liver stimulator (HSS) promote hepatocyte proliferation factor. Recently, our scholars cloned human homologues of rat ALR 〔2〕, and by constructing a prokaryotic expression vector, were highly expressed strains, and then obtain recombinant hALR. Preliminary research shows
