Moreover, they have self-renewal ability, multi-differentiation potential, and an important role in immune regulation. They can secrete a variety of cytokines to regulate the in vivo micro-environment. Therefore, ADSCs are the ideal seed ceils for stem ceils application. This paper reviews the location, isolation, surface markers, proliferation, differentiation and other biological characteristics of ADSCs, as well as their secretory function and relative researches. ADSCs are expected to become excellent seed cells for cell therapy and tissue engineering through in-depth studies.展开更多
