To investigate the effect of the Rho-kinase inhibitor, Y27632, on pig corneal endothelial cell (pCEC) culture, and on inflammation and immune regulation of the responses of human cells to pCECs.
pCECs were cultured with/without Y27632 to assess cell proliferation and in vitro wound healing assay. The level of MCP-1 and VEGF in pCECs stimulated with human TNF-α were measured. Proliferation of human PBMCs stimulated with pCECs, and cytokine production in human T cells, and monocyte migration after stimulation were investigated.
Y27632 promoted pCEC proliferation, prevented pCEC death, and enhanced in vitro wound healing. After stimulation, there were significantly lower levels of MCP-1 and VEGF measured in pCECs cultured with Y27632, and significantly reduced human PBMC proliferation, cytokine production, and monocyte migration.
The application of the Rho-kinase inhibitor will be beneficial when culturing pCECs, and may provide a novel therapy to reduce inflammation after corneal xenotransplantation.
研究Rho激酶抑制剂Y27632对猪角膜内皮细胞(pCEC)培养的影响,以及对人细胞对pCEC反应的炎症和免疫调节作用。
将pCEC在有/无Y27632的条件下培养,以评估细胞增殖和体外伤口愈合试验。检测用人肿瘤坏死因子-α刺激的pCEC中MCP-1和VEGF的水平。研究用pCEC刺激的人外周血单个核细胞(PBMC)的增殖、人T细胞中的细胞因子产生以及刺激后的单核细胞迁移。
Y27632促进pCEC增殖,防止pCEC死亡,并增强体外伤口愈合。刺激后,在用Y27632培养的pCEC中测得的MCP-1和VEGF水平显著降低,人PBMC增殖、细胞因子产生和单核细胞迁移显著减少。
Rho激酶抑制剂的应用在培养pCEC时将是有益的,并且可能为减少角膜异种移植后的炎症提供一种新的治疗方法。
