转化生长因子-β（TGF-β）是多功能多肽，可影响肿瘤的生长，它们介导特异性细胞表面受体（I型ALKS和Ⅱ型TGF-β受体）。作者分析在人体肝细胞癌（HCC）中3种TGF-β及其受体的作用。取18例HCC的部分肝切除标本．另取10例（女7例、男3例）的正常肝组织作为对照。供组织学检查的
Transforming growth factor-beta (TGF-beta) is a multifunctional polypeptide that affects the growth of tumors. They mediate specific cell surface receptors (type I ALKS and type II TGF-beta receptors). The authors analyzed the effects of three TGF-beta and its receptors in human hepatocellular carcinoma (HCC). Take 18 cases of HCC partial hepatectomy specimens. Another 10 cases (7 females and 3 males) of normal liver tissue were used as controls. For histological examination
