Early endothelial outgrowth cells (eEOCs) reproducibly have been shown to act protectively in acute ischemic kidney injury (AKI) and chronic kidney injury. Bone morphogenetic protein-5 (BMP-5) acted antifibrotically in human hypertensive nephropathy. The aim of the current study was to analyze effects of BMP-5 treatment in an eEOC-based therapy of murine AKI and 5/6-nephrectomy. Male C57/Bl6N mice were either subjected to unilateral renal artery clamping postuninephrectomy or to 5/6-nephrectomy. Untreated or BMP-5-pretreated murine eEOCs were injected into recipient animals at the time of reperfusion (AKI) or at 2 and 5 days after 5/6-nephrectomy. Analysis of renal function and morphology was performed at 48 h and at 6 wk (AKI) or at 8 wk (5/6 model). Cellular consequences of eEOC treatment were evaluated using different in vitro assays. AKI was mitigated significantly by injecting BMP-5-pretreated eEOCs. Renal function was improved at 48 h [corrected] after cell therapy. In 5/6-nephrectomy, the cells failed to act renoprotectively, [corrected] but proteinuria was reduced after administering untreated eEOCs." Next, the original version read as "BMP-5 acts as a potent eEOC agonist in murine AKI in the short [corrected] term. Cell effects in 5/6-nephrectomy are heterogenous, but untreated cells act antifibrotically [corrected] without any impact on EnMT.
早期内皮细胞(eEOCs)在急性肾缺血损伤(AKI)和慢性肾损伤中具有保护作用。骨形态发生蛋白-5(BMP-5)在人类高血压肾病中具有抗纤维化作用。本研究旨在分析 BMP-5 治疗对基于 eEOC 的 AKI 模型和 5/6 肾切除模型的影响。雄性 C57/Bl6N 小鼠在单侧肾动脉夹闭后进行单侧肾切除术或 5/6 肾切除术。在再灌注时(AKI)或在 5/6 肾切除术后 2 天和 5 天,将未经处理或 BMP-5 预处理的小鼠 eEOCs 注射到受者动物体内。在 48 小时和 6 周(AKI)或 8 周(5/6 模型)时,分析肾功能和形态学。使用不同的体外测定法评估 eEOC 治疗的细胞后果。注射 BMP-5 预处理的 eEOCs 可显著减轻 AKI。细胞治疗后 48 小时肾功能得到改善。在 5/6 肾切除术后,细胞未能发挥肾保护作用,但给予未经处理的 eEOCs 后蛋白尿减少。接下来,原文中“short-term”应改为“long-term”,“antifibrotically”应改为“angiogenic”,“EnMT”应改为“fibrosis”。
因此,翻译后的文本为:
