1978年,本室培养成功了一株人体肝癌细胞,命名为SMMC—7721人体肝癌细胞株,迄今已传至第66代,可作为肝癌防治和基础理论研究的细胞实验模型。人体肝瘤细胞株的建立,国内外均有报道,但专门记述人肝癌体外培养细胞超微结构的资料尚未见到,仅在一些建株报道中附有简短的超微结构的描述;因此,我们 In 1978, a human hepatoma cell line was successfully cultured in this chamber and named SMMC-7721 human hepatoma cell line. It has been transmitted to the 66th generation so far, and it can be used as a cell experimental model for the prevention and treatment of liver cancer. The establishment of human hepatoma cell lines has been reported at home and abroad, but the information specifically describing the ultrastructure of human hepatoma cells in vitro has not yet been seen, and only a brief description of the ultrastructure is given in reports of some established strains; therefore, we
