玉型胶原膜的类液晶结构对人脐带间充质干细胞黏附、增殖和分化性能的影响
Effects of Collagen Films with Liquid Crystal-liked Ordered Structure on Adhesion, Proliferation and Differentiation of Human Umbilical Cord Mesenchymal Stem Cells
摘要
Abstract
To mimic the ordered arrangement of typeⅠcollagen in natural tissue, a collagen films with liquid crystal-liked ordered surface were fabricated utilizing the liquid crystal state of concentrated collagen. And the effects of the topography on the behavior of human umbilical cord mesenchymal stem cells( hUCMSCs) were studied in vitro. The results showed that the collagen fibrils arranged directly on the surface of the collagen films when the concentration was over 120 mg/mL. This ordered structure improved significantly the adhesion and proliferation of hUCMSCs. In addition, it also increased the expression of osteogenic gene such as ALP, Collagen Ⅰ , RUNX2, Osterix, OCN and OPN, which meant that hUCMSCs had a stronger differentiation po-tency on the ordered surface than on the unordered surface.关键词
