间充质干细胞免疫调节作用研究进展

间充质干细胞是除造血干细胞以外的一种成体干细胞,具有自我更新、横向分化和免疫调节作用.间充质干细胞本身具有低免疫原性;在体外试验中表现出免疫抑制的作用,具有诱导免疫耐受的功能.间充质干细胞抑制T细胞对同种抗原和分裂素刺激的增生,阻碍细胞毒性T淋巴细胞细胞的发育;另外对抗原呈递细胞、自然杀伤细胞、B细胞等淋巴细胞都有相应的影响.

Immunological regulation of mesenchymal stem cell

Besides the haemopoietic stem cell, mesenchymal stem cell (MSC) is an adult stem cell in the marrow. It has the ability to self-renew, differentiate into various kinds of tissue and regulate the immunological system. MSC possess low immunogenicity. It shows the immunosuppressive ability in vitro and has function of inducing immune-tolerance. MSC suppress accrementition of T cell respone to the allotigen and mitogen and hinderes the development of cytotoxic T lymphocyte cell. In addition, MSC can influence antigen presenting cell, natural kill cell, B cell, and so on.
