近年来,已有不少学者从事甲种胎儿蛋白(AFP)的细胞定位与探索其在肝癌发病中的作用机理。我们曾观察到,AFP不仅存在于部分肝癌细胞的胞浆中,而且还出现在肝癌灶周围宿主肝细胞的原浆内,其阳性细胞率和显色强度远比肝癌细胞高,且与慢性肝病的活动有一定关系。本文拟从AFP In recent years, many scholars have engaged in the cellular localization of AFP and explored its role in the pathogenesis of HCC. We have observed that AFP not only exists in the cytoplasm of some liver cancer cells but also in the plasma of host liver cells around the liver cancer lesions. Its positive cell rate and color intensity are much higher than that of liver cancer cells, and it is associated with chronic liver disease. There is a certain relationship between the activities. This article is intended to be from AFP
