1.人直肠癌体外培养细胞系的建立杭州肿瘤医院实验病理研究室,经过三年多努力,建成了能在体外培养、传代的人直肠癌细胞系,定名为HR-8348,已在体外培养二年多,传代105次。由于肠道本身属于开放性器官,含有多种菌,污染机会较大,再加上癌细胞在培养过程中退化等原因,人直肠癌细胞系很难建成,国际上成功的也只有5例。该细胞系的建立为进一步研究该病病因、诊断和治疗,提 1. Human colorectal cancer cell line established in Hangzhou Experimental Hospital of Tumor Hospital, after three years of hard work, built in vitro culture, passage of human rectal cancer cell line, named HR-8348, has been cultured in vitro More than two years, pass 105 times. As the intestine itself is an open organ, contains a variety of bacteria, a greater chance of contamination, combined with cancer cells in the culture process of degradation and other reasons, difficult to build human rectal cancer cell lines, the international success of only 5 cases. The establishment of the cell line for further study of the etiology, diagnosis and treatment, mention
