Abstract:
Objective To investigate the expressions of hepatorna stem cell surface marker CD133 CD90 in tissues of hepatocellular carcinoma (HCC) and evaluate their related clinical significances. Method The expressions of CD133 CD90 were detected by immunohistochemical method in HCC tissues of 93 patients, and normal liver tissues of 10 cases. Results Among 93 cases with HCC, the positive expression of CD133 were found in 71 cases (76.3%), and CD90 positive expression in 64 cases (68.8%), and the percentage of positive cells were (6.4±3.3)% and (4.3±3.9)% respectively. No positive expression of CD133 and CD90 was found in normal liver tissues (P<0.01). CD133, CD90 expressions in the HCC tissues of TNM stage Ⅲ-Ⅳ [(8.1±3.7)%,(5.7±4.2)%] were higher than those of TNM stage Ⅰ - Ⅱ [(4.1±2.3)%,(2.3±1.9)%] (P<0.01). Spearman correlation analysis indicated that the expressions of CD133 and CD90 were up-regulated as the pathohistology grades increased (P<0.05). Positive correlation was observed between CD133 and CD90 expression (r=0.402, P<0.01). Conclusions CD133, CD90 positive cells exist in HCC tissues, their expressions positively relate to the TNM stage and the pathohistology grades for HCC patients.
