干细胞是指来自胚胎、胎儿或成人的一类具有长期自我复制和多向分化潜能的特殊细胞。干细胞分两大类,即胚胎干细胞和成体干细胞。骨髓干细胞是成体干细胞的主要成分,包括间充质干细胞和造血干细胞两大类,骨髓基质非造血细胞中含有间充质干细(mesenchymal stem cells,MSCs)。已有研究证实这类干细胞在不同诱导条件下能够分化成骨、软骨、脂肪、肌肉、肌腱、血管内皮、心肌、肝脏、
Stem cells refer to a group of special cells that have long-term self-replication and multidirectional differentiation potential from embryos, fetuses, or adults. Stem cells fall into two categories, namely, embryonic stem cells and adult stem cells. Bone marrow stem cells are the main components of adult stem cells, including two types of mesenchymal stem cells and hematopoietic stem cells, and mesenchymal stem cells (MSCs) in bone marrow stromal non-hematopoietic cells. Studies have shown that these stem cells can differentiate into bone, cartilage, fat, muscle, tendon, vascular endothelium, myocardium, liver,
