摘要:

归巢是干细胞发挥组织修复作用的初始及关键环节。目前研究表明骨髓间充质干细胞无法高效地归巢至靶组织成为其修复效果的主要障碍。预处理策略为促进干细胞归巢提供了新思路。组织预处理通过改变局部微环境,细胞预处理通过上调干细胞表面受体或因子的表达,均能促进干细胞归巢,从而改善其对损伤组织的修复效果。

Abstract:

Homing is the initial and key procedure of stem cells-based tissue restoration.Current studies have shown that the inability to recruit these mesenchymal stromal cells to target tissue with high efficiency remains a significant barrier to tissue restoration.Preconditioning strategy provides a new sight in promoting homing of stem cells.Altered local microenvironment via tissue preconditioning and enhanced expression of surface receptors or factors via cellular preconditioning are both capable of enhancing stem cell homing,thus facilitates restoration of impaired tissue.
