胚胎干细胞是一大类未分化的全能干细胞,具有无限增殖、自我更新和多向分化的潜能。在过去的20年中,由于培养技术、分离技术的提高,以及对干细胞特征如细胞表面抗原、遗传标记认识的加深,鼠和人的干细胞己建系上百株。胚胎干细胞己展示出很好的临床应用前景,同时也将为基因功能 Embryonic stem cells are a large group of undifferentiated pluripotent stem cells that have the potential for unlimited proliferation, self-renewal and multidirectional differentiation. Over the past two decades, mouse and human stem cells have built hundreds of lines due to advances in culture techniques, separation techniques, and increased awareness of stem cell features such as cell surface antigens and genetic markers. Embryonic stem cells have shown good clinical application prospects, but also will be gene function
