胚胎干细胞技术的研究进展

Progress of Embryonic Stem Cell

干细胞可以分为成体干细胞和胚胎干细胞两类,是当前生物医学领域的一个热点。由于干细胞在医学领域有巨大应用前景,世界各国都对此给予了相当的重视;投入大量资金支持本国的科学家从事干细胞的科学研究。目前,干细胞的研究还处于试验室阶段,很多技术难题还没有解决,尤其是胚胎干细胞的不定向分化问题,以及一些伦理方面的争议。宗教界人士和社会论理学方面的人士对于干细胞的研究还有异议。集中论述了胚胎干细胞的研究进展和医学功用。

Human Embryonic stem cell （HESC）research was a hotspot of biomedical research.Based on theory of embryonic stem cell,human embryonic stem cell could give a promised futurein offering therapeutic remedy for debilitating disease and injury.The government of advanced country paid enough attention to the project of embrynic stem cell.They fund scientists of their own too much.There still exist too much suspending problem in embrynic research.Hot ethical and religious debate erupted between scientists and Social ethical group.The linchpin lies in how to define the concept of life and how to keep the embryonic differentiated into proper orientation.In this paper,we briefly introduced the progress of embryonic stem cell in clinic application and striking ethical debate on embryonic stem cell research.
