摘要: 目的:探究has_circ_0008717在人羊膜间充质干细胞上清(hAMSC-CM)促进人脐静脉内皮细胞(HUVECs)血管生成过程中的作用。方法:通过划痕实验、Transwell实验及成管实验检测hAMSC-CM对HUVECs迁移及成管能力的影响,实时荧光定量RT-PCR筛选上调的circRNA(has_circ_0008717);小干扰RNA(siRNA)下调HUVECs内has_circ_0008717水平后,实时荧光定量RT-PCR检测血管内皮生长因子A(VEGFA)表达水平变化,划痕实验、Transwell实验及成管实验观察其对hAMSC-CM促进HUVECs迁移及成管的影响。结果:hAMSC-CM可明显促进HUVECs迁移及成管能力(P<0.05),HUVECs中has_circ_0008717升高最为明显(P<0.05),而敲低has_circ_0008717可明显抑制hAMSC-CM促进HUVECs迁移、成管和VEGFA的表达(P<0.05)。结论:hAMSC-CM可通过has_circ_0008717增强HUVECs的成管能力。

Abstract: Objective:?To investigate the role of has_circ_0008717 during the process that human amnion-derived mesenchymal stem cells (hAMSCs) promote angiogenesis of human umbilical vein endothelial cells (HUVECs). Methods:?Wound healing assay, Transwell migration and tube formation were used to confirm the pro-angiogenic capacity of conditioned medium from hAMSCs (hAMSC-CM) on HUVECs, qRT-PCR and were used to detect the change of level of the potential pro-angiogenic relative circRNAs and genes in HUVECs after treated with hAMSC-CM, among them, has_circ_0008717 and VEGFA attracted our attention. siRNAs specially targeted has_circ_0008717 were used to down-regulate the level of has_circ_0008717 in HUVECs treated with hAMSC-CM, and then qRT-PCR was used to detect were used to evaluate the change of level of VEGFA caused by down-regulation of has_circ_00087, afterwards,wound healing assay, Transwell migration and tube formation were used to assess the effects of down-regulation of has_circ_0008717 on HUVECs treated with hAMSC-CM. Results: Enhanced migration and tube formation in HUVECs induced by hAMSC-CM were observed (P<0.05). And has_circ_0008717 been the mostly up-regulated circRNA among several potential pro-angiogenic relative circRNAs was selected for further investigation (P<0.05). Increased expression of vascular endothelial growth factor A (VEGFA) was observed among a few pro-angiogenic relative genes (P<0.05). Furthermore, these can be inhibited by silencing has_circ_0008717 in HUVEC treated with hAMSC-CM (P<0.05). Conclusion: has_circ_0008717 might be involved in the pro-angiogenic role of hAMSC-CM in HUVECs.
