摘要
目的研究表皮生长因子(EGF)和碱性成纤维生长因子(bFGF)在体外对大鼠巩膜成纤维细胞生长的影响。为进一步了解近视发生的分子机制提供依据。方法采用植块法培养大鼠巩膜成纤维细胞。细胞经传代纯化鉴定后,取第3~4代细胞加入不同浓度的EGF(0.1~200ng/mL)、bFGF(0.1~50ng/mL)。分别培养24、48、72h用四甲基偶氮唑盐(MTT)法检测细胞的增殖密度。观察不同浓度、时间下细胞增殖情况。结果发现0.1~100ng/mL的EGF和0.1~50ng/mL的bFGF对大鼠巩膜成纤维细胞均有明显的促增殖作用,且呈剂量相关性。结论一定浓度的EGF、bFGF对体外培养的大鼠巩膜成纤维细胞的生长具有促进作用。
Purpose To study the effects of epidermal growth factor ( EGF ) and basic fibroblast growth factor ( bFGF ) on scleral fibroblasts proliferation in vitro. Methods The rat scleral fibroblasts were grown in tissue culture,then were treated with different doses of EGF ( 0.1,1. 0,10,100 and 200 ng/mL ) or bFGF (0.1,0.5,1.0,10 and 50 ng/mL ) individually. The effects of EGF and bFGF on scleral fibroblasts proliferation were measured by MTT assay. Results EGF induced proliferation significantly at concentrations of 0.1,1.0,10 and 100 ng/mL in comparison with control, but in 200 ng/mL EGF didn't induced proliferation, bFGF induced proliferation significantly at concentra- tions of 0.1,0. 5,1. 0,10 and 50 ng/mL. Conclusions The results suggested that EGF and bFGF could regulate the growth of rat scleral fibroblasts in vitro.
