脂肪间质干细胞研究进展

Biology and Future Clinical Perspectives of Adipose-tissue Derived Mesenchymal Stem Cells

脂肪间质干细胞,是脂肪组织中一类多能性干细胞。在体内、体外条件下,可诱导分化形成脂肪、骨、软骨、肌肉等组织类型细胞。人体脂肪组织十分丰富,用其分离脂肪间质干细胞可避免分离胚胎干细胞所面临的道德伦理问题和获取极少量骨髓分离骨髓间质干细胞时给供者带来极大痛苦等。因此脂肪间质干细胞可作为组织再生工程的干细胞理想的替代资源。重点论述脂肪间质干细胞的研究进展,并探讨其临床应用前景。

Adipose-tissue mesenchymal stem cells, is one kind of multipotent stem cells, can differentiate adipogenic, osteogenic, chondrogenic, myogenic cells and so on in vitro and in vivo. Human adipose tissue is plentiful, easily harvested in large quantity with little patient discomfort. Adipose-tissue derived mesenchymal stem cells may be an alternative stem cell source for mesenchymal tissue regeneration and engineering without ethical consideration of embryonic stem cells and severe pain resulted by bone marrow procurement. The research work on adipose-tissue mesenchymal stem cells and future clinical perspectives were reviewed.
