在再生医学中干细胞是个非常吸引人的的领域。干细胞在人的发育和更新中有着至关重要的作用，他是一类可以自我复制并能保持分化成多种细胞类型能力的细胞，干细胞在所有的时期都有发现，从能发育成所有细胞的胚胎干细胞到负责组织再生的成人干细胞。根据干细胞的性质我们认为干细胞有改变退行性疾病或者重要的跌打损伤治疗方法。在这里我简单的总结肝脏、心脏、肾脏、软骨以及骨再生方面的文献。

Stem cells are one of the most fascinating areas in regenerative medicine today. They play a crucial role in the development and regeneration of human life and are defined as cells that continuously reproduce themselves while maintaining the ability to differentiate into various cell types. Stem cells are found at all developmental stages, from embryonic stem cells that differentiate into all cell types found in the human body to adult stem cells that are responsible for tissue regeneration. The general opinion postulates that clinical therapies based on the properties of stem cells may have the potential to change the treatment of degenerative diseases or important traumatic injuries in the "near" future. We here briefly review the literature in particularly for the liver, heart, kidney, cartilage, and bone regeneration.
