摘 要: 种子细胞、生物材料和生长因子是组织工程三要素。生物材料模拟体内细胞外基质,为细胞提供良好的生长附着环境,维持细胞的活力和功能。材料表面的理化性质和表面改性分子直接影响细胞的粘附、增殖、迁移和分化等细胞行为,进而影响细胞功能和组织再生效果。材料表面修饰分子是细胞表面粘附和生长的直接接触位置,因此细胞与生物材料表面修饰分子的相互作用是组织工程的关键。文中重点介绍表面修饰分子对细胞表型及功能的影响,为组织工程关键问题的研究提供参考。

Abstract: Seed cells, biomaterials and growth factors are three important aspects in tissue engineering. Biomaterials mimic extra cellular matrix in vivo, providing a sound environment for cells to grow and attach, so as to maintain cell viability and function. The physicochemical properties and modification molecules of material surface mediate cell behaviors like cell adhesion, proliferation, migration and differentiation, which in turn affect cellular function and tissue regeneration efficacy. Furthermore, the modification molecules of material surface are the direct contact point for cell adhesion and growth. Therefore, the interactions between cells and surface modification molecules are the key to tissue engineering. This review summarizes the effects of surface modification molecules on cell phenotypes and functions.
Keywords: extra cellular matrix, integrin, surface modification, mechanotransduction, stem cell, growth factor

Abstract: Objective To observe the clinical effect of delivering 0.5% tranexamic acid solution into skin with microneedles
for facial skin dull of Chinese women.
Methods A total of 60 healthy subjects were enrolled for this study and were respectively divided into 2 groups. 60 cases volunteers were treated by deliverying solution into skin through micropores which the microneedles made. In the first group, volunteers were treated by deliverying physiological saline solution into skin . In the second group, volunteers were treated by deliverying 0.5% tranexamic acid solution into skin . One session every 7 days, all 60 volunteers were treated 8 times. We asses its effect by questionaires for subjective evaluation and side effect, and objective evaluation with digital skin analyzers to record raw pictures and data before and after treatment. Retesting TEWL, skin hydration, erythema dose, melanin value and skin elasticity at the ending of 1, 2 months after all treatment.
Results There was no significant difference in TEWL, skin hydration , erythema dose, melanin and skin elasticity between the saline group and the 0.5% tranexamic acid solution group. Melanin of 0.5% tranexamic acid solution group was relatively lower than the saline group. There was no significant difference in facial photo before and after treatment in the saline group, skin colour was obviously pale compared to that before treatment in the 0.5% tranexamic acid solution group. The subjects and doctors’ satisfaction of the saline group was relatively lower than that of the 0.5% tranexamic acid solution group . There was no adverse reaction report both in the saline group and the 0.5% tranexamic acid solution group. In the 0.5% tranexamic acid solution group , there were significant differences in melanin value before and 1 month after the treatment , while there were no statistical differences before and 2 month after the treatment .
Conclusion Delivering 0.5% tranexamic acid solution into skin with microneedles can significantly improve the facial skin dull of Chinese women .
