研究方向:体细胞重编程与诱导多能干细胞
研究工作:
体细胞重编程(somatic reprogramming)指的是分化的体细胞在特定的条件下被逆转后恢复到全能性状态或多能性状态,或者形成多能干细胞系,或者进一步发育成一个新的个体的过程。诱导体细胞重编程的方法有许多,如核移植、细胞融合、细胞提取物诱导、化学诱导以及诱导多能干细胞(induced pluripotent stem cell, Ipsc)技术等。但到目前为止,能诱导体细胞产生具有功能的重编程的方法只有核移植和iPS技术,其他的方法只能在细胞、分子或生化水平上产生诱导。然而所有这些诱导体细胞重编程的技术都很不成熟,效率很低,体细胞重编程的机制还不清楚。虽然如此,体细胞重编程却有着非常广泛的应用前景,不仅在基础理论研究中,而且在应用研究中,例如家畜繁殖、动物保护以及人口健康等领域都有着重要的作用。因此,研究体细胞重编程的机制,提高重编程的效率以及开展体细胞重编程的应用研究显得尤为必要和紧迫。 本实验室将开展以下几方面的研究: (1)完善核移植及iPS技术诱导体细胞重编程的方法,提高体细胞重编程的效率; (2)探讨核移植与iPS技术诱导体细胞重编程的机制; (3)建立新的诱导体细胞重编程的方法; (4)开展体细胞重编程的应用研究。
