摘要:

背景:重组人表皮生长因子和碱性成纤维生长因子的制剂临床上已经用于眼表创伤的修复,但是对于使用何种浓度的生长因子就能够最大程度的促进愈合以及两种生长因子促进创面愈合的效果比较一直存在争议。
目的:初步观察重组人表皮生长因子、碱性成纤维生长因子对培养的人角膜上皮细胞克隆的影响。
方法:用不同浓度的重组人表皮生长因子和碱性成纤维生长因子作用于体外培养的人角膜上皮细胞,应用四甲基偶氮唑盐比色法分别在不同浓度的生长因子作用人角膜上皮细胞3,5,7 d后检测人角膜上皮细胞的增殖能力;平板克隆形成实验法观察细胞克隆形态及计算细胞克隆形成率。
结果与结论:不同质量浓度的重组人表皮生长因子和碱性成纤维生长因子分别对人角膜上皮细胞干预5 d后,重组人表皮生长因子和碱性成纤维生长因子在10 μg/L质量浓度时MTT值最大;质量浓度10 μg/L重组人表皮生长因子促进人角膜上皮细胞克隆形成率高于质量浓度10 μg/L碱性成纤维生长因子(P=0.02)。结果证实,重组人表皮生长因子和碱性成纤维生长因子均能促进人角膜上皮细胞增殖并增加其克隆形成能力。质量浓度10 μg/L 重组人表皮生长因子干预5 d促进人角膜上皮细胞克隆形成效果最好。

Abstract:

BACKGROUND: The preparation of recombinant human epidermal growth factor (rhEGF) and basic fibroblast growth factor (bFGF) has been clinically used in the repair of ocular surface trauma. However, the concentration of these growth factors that achieve the maximal healing effect and the comparison of two kinds of growth factors on promoting wound healing are still controversial.
OBJECTIVE: To investigate the effect of rhEGF and bFGF on the cloning of human corneal epithelial cells.
METHODS: The human corneal epithelial cells cultured in vitro were interfered with rhEGF and bFGF under different concentrations. The proliferation of human corneal epithelial cells was detected using MTT assay after 3, 5, 7 days of growth factors treatment. Plate clone formation assay was applied to observe the morphology of cell clone and analyze clone formation rate of human corneal epithelial cells.
RESULTS and CONCLUSION: MTT value shows that 10 μg/L rhEGF and 10 μg/L bFGF on day 5 were the most powerful concentration. The clone formation rate of human corneal epithelial cells after treated with 10 μg/L rhEGF was higher than that with 10 μg/L bFGF (P = 0.02). The results confirmed that both rhEGF and bFGF could promote the proliferation and increase clone formation ability of human corneal epithelial cells. 10 μg/L rhEGF for 5 days achieves the best effect on promoting clone formation of human corneal epithelium cells.
