间质干细胞 (MSCs)是指存在于骨髓间质中具有自我复制能力 ,并在特定条件下分化为中胚层起源组织的非造血组织干细胞。MSCs具有多向分化潜能和强大的增殖能力 ,由于易从骨髓中分离及体外扩增纯化 ,在组织工程领域倍受关注。由于近二年来发现了MSCs可以横向分化 (Transdifferent
Mesenchymal stem cells (MSCs) refer to non-hematopoietic stem cells that exist in the bone marrow interstitium and have the ability to self-replicate and differentiate into mesodermal origin under certain conditions. MSCs have multi-directional differentiation potential and strong proliferative capacity. Due to their easy isolation from bone marrow and their purification in vitro, MSCs attract much attention in the field of tissue engineering. Since nearly two years have been found that MSCs can be transversely differentiated (Transdifferent
