作者用~3H-TdR掺入、染料排斥及干细胞集落形成三种方法,检测了人低分化鼻咽癌上皮细胞系(CNE-2Z)的生长能力对33种湛江沿海海洋生物的反应。发现一种检测比值低于40％的有6～15种,三种比值均降低的四种。这些海洋生物(特别是后者)可能有某种抑制瘤细胞生长的作用。 Using the methods of ~3H-TdR incorporation, dye exclusion, and stem cell colony formation, the authors examined the response of human poorly differentiated nasopharyngeal epithelial cell line (CNE-2Z) to 33 coastal marine organisms in Zhanjiang. It was found that there were six to fifteen kinds of detection ratios lower than 40%, and the three kinds of ratios were all reduced. These marine organisms (especially the latter) may have some effect of inhibiting the growth of tumor cells.
