We found that 1 mutant EG4 cells showed typical characteristics of pluripotent stem cells which had no obvious difference with wild cells; 2 When induced by 10〓 M retinoic acid , mutant EG4 cells differentiated into adipocytes with high frequency compared with mutant cells, suggested that EGFR plays a role in adipocyte differentiation; 3 when injected into nude mice, mutant teratocarcinomas contained a large amount of connective tissues as well as skeletal muscle, while wild EG4 cells produced frequently cartilage, keratinocyte and neuroepithelium.

我们建立了稳定表达胞内区功能缺失的外源EGFR cDNA片段的EG4细胞，分析其生长分化特性，发现 1）突变型细胞可在未分化状态下维持长时间的增殖，表明EGFR对EG多能干细胞表型无明显影响；2）〓 M的维甲酸A(retinoid acid A，RA)诱导后，大部分对照组细胞分化为脂肪细胞，而突变型细胞分化为脂肪细胞的比例明显较少，表明EGFR在脂肪细胞的发育分化中具有一定的调节作用；3）畸胎瘤切片分析显示，突变型瘤组织分布有大量的未分化细胞和结缔组织，分化细胞以肌肉细胞为主；对照组瘤组织含丰富的角质上皮、软骨、神经管等依赖EGFR的分化组织。
