文题释义:
前列腺素E1:
是广泛存在体内的生物活性物质,1960年由Bergsrtoem等首先分离出并详细研究其分子结构,具有扩张血管、降低周围血管阻力、稳定生物膜降低血小板黏附率、改善血液黏度和红细胞变形能力、抑制血小板黏附聚集及血栓素A2生成、抑制炎症反应等作用。
血管内皮生长因子:是Ferrara等在1989年发现,能特异性的作用于内皮细胞,是促进细胞有丝分裂和血管生成的一种细胞因子。近年来国内外学者发现血管内皮生长因子具有促进血管生成及侧支循环形成、保护梗死心肌等作用,是目前研究最多并且特异性最强的一种促血管生长因子。

 

摘要
背景:
目前还缺乏前列腺素E1对骨髓间充质干细胞旁分泌和迁移影响的研究。
目的:观察前列腺素E1与骨髓间充质干细胞共培养对细胞旁分泌和迁移的影响。
方法:取第3代骨髓间充质干细胞与10 μg/L前列腺素E1共培养,在3,6,9,12,24,48,72 h各时间点收集培养孔内上清液100 μL,利用酶联免疫吸附法检测不同时间骨髓间充质干细胞分泌血管内皮生长因子水平。采用细胞划痕实验及Transwell迁移实验观察前列腺素E1干预后骨髓间充质干细胞的迁移能力。
结果与结论:①前列腺素E1作用3 h后骨髓间充质干细胞分泌血管内皮生长因子水平开始升高,作用24 h时血管内皮生长因子分泌达到峰值,随后逐渐下降;②细胞划痕实验和Transwell迁移实验显示,前列腺素E1作用后迁移的骨髓间充质干细胞显著增多(P < 0.05);③结果可见,前列腺素E1可促进骨髓间充质干细胞分泌血管内皮生长因子,并能提高它的迁移能力。

Abstract:

BACKGROUND: Currently, there are few studies about prostaglandin E1 in the paracrine and migration of bone marrow mesenchymal stem cells.
OBJECTIVE: To explore the effects of prostaglandin E1 in the paracrine and migration of bone marrow mesenchymal stem cells.
METHODS: Bone marrow mesenchymal stem cells isolated from Sprague Dawley rats were cultured in vitro. Passage 3 cells were co-cultured with prostaglandin E1 at concentrations of 10 μg/L, and then culture supernatant was collected at 3, 6, 9, 12, 24, 48, and 72 hours after co-culture. The level of vascular endothelial growth factor was detected by enzyme- linked immunosorbent assay. Effects of prostaglandin E1 on the migration of bone marrow mesenchymal stem cells were detected by Transwell assay and cell scratch assay.
RESULTS AND CONCLUSION: After treatment with prostaglandin E1 for 3 hours, bone marrow mesenchymal stem cells began to secrete vascular endothelial growth factors, and the secretion level was peaked at 24 hours and then gradually decreased. Results from the Transwell assay and cell scratch assay showed that the migration ability of bone marrow mesenchymal stem cells was significantly promoted by prostaglandin E1 (P < 0.05). Overall findings reveal that prostaglandin E1 promotes the secretion of vascular endothelial growth factor from bone marrow mesenchymal stem cells and enhances cell migration.
