摘要: 采用H2O2对人肾小管上皮细胞(HKC)进行损伤. HKC损伤后,其活力降低,并表达骨桥蛋白(OPN). 损伤细胞促进草酸钙晶体的成核、聚集,并促进一水草酸钙(COM)晶体的形成,但对晶体生长的促进作用不明显. 本文结果提示,HKC细胞损伤后增加了肾结石形成的危险性.

Abstract: Human renal tubular epithelial cells (HKC) were injured by H2O2. Cell damage caused the decreased viability of HKC, and the increased expression of osteopontin (OPN), thus, the nucleation and aggregation of calcium oxalate crystals were promoted, and the percentage of the induced calcium oxalate monohydrate (COM) crystals increased, but the effect on growth of calcium oxalate crystals was not significant. The results suggest that damage of renal tubular epithelial cells might increase the risk of kidney stone formation.

Key words: Calcium oxalate, cell regulation, osteopontin, biomineralization, HKC cell
