近年来人们对干细胞的认识逐渐增加,当知道干细胞具有独特的分化潜能,能治愈组织难以自愈的创伤,能治疗临床上难以治愈的疾病,甚至可以使人返老还童,让青春永驻时,人们便开始企盼着干细胞时代的到来。本文就干细胞近年来在其生物学特性及应用方面进展做一综述。 In recent years, people’s understanding of stem cells has been gradually increasing. When people know that stem cells have unique differentiation potential, they can heal the wounds that are hard to be healed by the tissue, treat the clinically unmanageable diseases, and even rejuvenate the youth, They began to look forward to the arrival of stem cell era. In this paper, the progress of stem cells in recent years in their biological characteristics and applications are reviewed.
