利用标记物质和放射自显影来测定细胞周期,是细胞动力学的重要研究手段之一。50年代后期以来,许多学者用这种方法,广泛地检查了多种动物肿瘤和人类肿瘤细胞,在一般情况下和药物影响下的细胞动力学变化,取得了有意义的成果。通过种种研究,不但对一些细胞株,动物移植瘤和人类肿瘤的生长规律以及它们对抗癌药反应的了解深入了一步,而且在方法学和重要参数的表达上,也逐渐发展、完善。国内一些单位正在开展这方面的工 The use of labeled substances and autoradiography to determine the cell cycle is one of the important research methods for cellular dynamics. Since the late 1950s, many scholars have used this method to extensively examine a variety of animal tumors and human tumor cells. Under general circumstances and under the influence of drugs, cell dynamics has achieved significant results. Through various studies, not only has a deeper understanding of the growth law of some cell lines, animal xenografts and human tumors, and their anticancer drug reactions, but also gradually developed and improved in the expression of methodologies and important parameters. Some domestic units are working in this area
