摘要:

目的 不同浓度生长因子对细胞增殖有不同的效应,本研究主要寻找促进细胞增殖的最佳 血小板衍生生长因子(platelet derived growth factor,PDGF⁃BB)和血管内皮生长因子(vascular endothelial growth factor,VEGF⁃A)浓度。方法 将慢病毒 GFP 转染至人脐静脉内皮细胞(human umbilical vein endo⁃ thelial cell,HUVEC),并将 PDGF⁃BB VEGF⁃A 以浓度各进行分组:0 μg/mL GFs 组(Control 组),0.02 μg/mL GFs 组,0.2 μg/mL GFs 组,2 μg/mL GFs 组,5 μg/mL GFs 组。将 GFP⁃HUVEC 接种到孔板或者凝胶中,培养一定时间后利用荧光显微镜或者 CCK⁃8 检测其增殖效果。结果 (1)转染了 GFP HUVEC 状态良好, 镜下可见较强荧光。(2)孔板内辅以不同浓度生长因子培养HUVEC,分别在2 μg/mL PDGF⁃BB(P < 0.001)和 0.02 μg/mL VEGF⁃A(P < 0.000 1)细胞有最高的增殖活性。(3)CCK⁃8 显示在 2 μg/mL PDGF⁃BB(P < 0.05 0.02 μg/mL VEGF⁃A(P < 0.001)细胞有最高的增殖活性(4)将细胞包裹进水凝胶内并在培养基中给予 不同浓度生长因子培养,分别在 2 μg/mL PDGF⁃BB(P < 0.01)和 0.02 μg/mL VEGF⁃A(P < 0.01)细胞有最高 的增殖活性。结论 2 μg/mL PDGF⁃BB 0.02 μg/mL VEGF⁃A 能对细胞产生的增殖效果最好,过高浓度的生长因子对于细胞可能有抑制作用。

Abstract:

Objective The same concentration of growth factor has different effects on cell proliferation and the aim of this study was to find the optimal concentrations of PDGF⁃BB and VEGF⁃A for HUVEC proliferation. Methods Lentivirus GFP was transfected into HUVECs and PDGF⁃BB and VEGF⁃A were grouped in concentra⁃ tions:0 μg/mL GFs(Control),0.02 μg/mL GFs,0.2 μg/mL GFs,2 μg/mL GFs,5 μg/mL GFs. GFP⁃HUVEC was inoculated into the porous plate or gel and cultured for a certain time. Then the proliferation of GFP⁃HUVEC was detected by Fluorescence microscope or CCK⁃8. Results (1)HUVEC transfected with GFP was in good condi⁃ tion and showed strong fluorescence under microscope.(2)HUVEC was cultured with different concentrations of growth factors in the hole plate. The cells had the highest proliferative activity at 2 μg/mL PDGF⁃BB(P < 0.001 and 0.02 μg/mL VEGF⁃A(P < 0.000 1),respectively.(3)CCK⁃8 showed the highest cell proliferative activity in 2 μg/mL PDGF⁃BB(P < 0.05)and 0.02 μg/mL VEGF⁃A(P < 0.001).(4)The cells were encapsulated in the hy⁃ drogel and cultured in the medium with different concentrations of growth factors. The cells had the highest prolifer⁃ ative activity at 2 μg/mL PDGF ⁃BB(P < 0.01)and 0.02 μg/mL VEGF ⁃A(P < 0.01),respectively. Conclusion HUVECs respectively had the best effect of cell proliferation in 2 μg/mL PDGF⁃BB and 0.02 μg/mL VEGF⁃A. How⁃ ever,high concentrations of growth factors may have an inhibitory effect on them.
