摘要:

目的 探讨基质细胞衍生因子-1α(SDF-1α)及白细胞介素-1β(IL-1β)诱导内皮细胞表达淋巴管表型的作用。方法 SDF-1α和IL-1β分别诱导内皮细胞株CRL-1730,用Real-time PCR、Western blotting及免疫细胞化学等方法检测其内皮及淋巴管标志物,的表达情况。结果 SDF-1α诱导培养之后,CRL-1730细胞株的内皮细胞标志物血管性血友病因子(vWF)、血管内皮钙黏蛋白(VE-cadherin)、血管内皮生长因子受体(VEGFR)2随其浓度增高而表达降低,淋巴管标志物平足蛋白(podoplanin)、同源异形盒蛋白-1(Prox-1)和淋巴管内皮透明质酸受体-1(LYVE-1)随其浓度增高而表达增高。IL-1β诱导之后,CRL-1730细胞株的vWF、VEGFR2和podoplanin、prox-1、LYVE-1的变化趋势同SDF-1α,而VE-cadherin的表达量基本不变。结论 SDF-1α和IL-1β都能够诱导血管内皮细胞表达淋巴管标志物。

Abstract:

Objective To investigate the effect of stromal cell-derived factor-1α (SDF-1α) and interleukin(IL-1β) on inducing vascular endothelial cells to express lymphatic phenotype. Methods The CRL-1730 cell line was cultured and treated with SDF-1α or IL-1β. The expression of endothelial cell markers and lymphatic endothelial cell markers were investigated with Real-time PCR, Western blotting and immunocytochemistry. Results In CRL-1730 cell line, endothelial cell markers such as voln willebrand factor (vWF), VE-cadherin, vascular endothelial growth factor receptor(VEGFR)2, were dose dependently down-regulated after SDF-1α stimulation, while lymphatic phenotypes such as Prox-1, podoplanin and lymphatic vessel endothelial hyaluronan receptor-1(LYVE-1), were dose-dependently up-regulated after SDF-1α stimulation. The changes of vWF, VEGFR2 and podoplanin, Prox-1, LYVE-1 expression after IL-1β stimulation was similar to that after SDF-1α while expression of VE-cadherin changed slightly. Conclusion SDF-1α and IL-1β are able to induce vascular endothelial cell expressing lymphatic phenotype.
