【摘要】 对L929细胞株的生物学特征进行了初步研究。结果表明,该L929细胞株是一株易于培养、集落清晰的雄性细胞。集落形态分为致密型与疏散型2种,集落生成数与血清浓度在1％～10％之间呈明显剂量依赖性,细胞倍增时间25.49小时。L929细胞株的生物学特征符合成纤维细胞的生物学特征。更多还原

【Abstract】 The biological characteristics of L929 cell line were investigated. It was found that L929 cell line was a male cell line which was easy to culture and formed clear colonies. Colonies could be divided into two types: dense type and spersed type. It showed positive correlation be-tween the number of colony formation and 1%-10% serum concentrations. The doubling time of L929 cell was 25.49 hrs. It is in accordance with the biological characteristics of fibroblasts. This investigation provided us a good modei for the study of cells.更多还原
