细胞失去对生长调节信号的应答,是肿瘤发生、发展的1个重要因素。转化生长因子β1(ｔｒａｎｓｆｏｒｍｉｎｇｇｒｏｗｔｈｆａｃｔｏｒβ1,ＴＧＦβ1)是人体多种上皮组织细胞的负生长调控因子,即细胞对ＴＧＦβ1负生长调控作用的逃逸可能是癌变过程中的1个重要环节。近年来研究
Cells lose the signal of growth regulator response, tumor occurrence and development of an important factor. Transforming growth factor β1 (TGFβ1) is a negative regulator of human epithelial cells. Escape of TGFβ1 cells may be one of the important steps in carcinogenesis. In recent years, research
