摘要
骨髓间充质干细胞（BMSCs）是骨髓中除造血干细胞外的另一类具有高度可塑性的细胞群体,可从体内器官组织中分离出且具备在体外培养、诱导和扩增等特性,其在基因治疗、细胞治疗及组织工程等领域具有广泛的临床应用前景.近年来,BMSCs被越来越多地应用于自体移植进行细胞治疗和组织工程中,但是并不是所有的BMSCs都适用于自体移植.BMSCs会出现生物衰老,生物衰老的BMSCs分为年龄所致衰老和连续传代所致衰老.衰老的BMSCs因其生物学行为发生改变,其自体移植的成功率也随之降低.结合近年来有关BMSCs的研究进展,对衰老的BMSCs的生物学行为进行综述.
Bone marrow mesenchymal stem cells （BMSCs）,which can be isolated from organs and tissues,are cell populations with high degree of plasticity,similar to hematopoietic stem cells in bone marrow,and can be in vitro cultured,induced and amplified.BMSCs are increasingly used in gene therapy,cell therapy and tissue engineering.BMSCs have been currently studied in a number of autologous transplantations,while not all BMSCs are suitable for autologous transplantation.BMSCs exhibit biological aging gradually when cultured in vitro.Biological aging can be divided into age-induced senescence and long-term passage induced senescence.Aging BMSCs demonstrate changes in biological behaviour which reduces the success rate of autologous transplantation.In this review,biological aging BMSCs are discussed in order to provide help for the transplantation of BMSCs.
