Abstract

The kidney is the most important organ for water homeostasis and waste excretion. It performs several important physiological functions for homeostasis: it filters the metabolic waste out of circulation, regulates body fluid balances, and acts as an immune regulator and modulator of cardiovascular physiology. The development of in vitro renal disease models with pluripotent stem cells (both human embryonic stem cells and induced pluripotent stem cells) and the generation of robust protocols for in vitro derivation of renal-specific-like cells from patient induced pluripotent stem cells have just emerged. Here we review major findings in the field of kidney regeneration with a major focus on the development of stepwise protocols for kidney cell production from human pluripotent stem cells and the latest advances in kidney bioengineering (i.e. decellularized kidney scaffolds and bioprinting). The possibility of generating renal-like three-dimensional structures to be recellularized with renal-derived induced pluripotent stem cells may offer new avenues to develop functional kidney grafts on-demand.

摘要

肾脏是维持水平衡和排泄废物的最重要器官。它执行多项重要的生理功能以维持体内平衡:它从循环中滤出代谢废物,调节体液平衡,并作为免疫调节剂和心血管生理的调节者。利用多能干细胞(人类胚胎干细胞和诱导多能干细胞)开发体外肾脏疾病模型以及从患者诱导多能干细胞体外衍生肾特异性样细胞的强大方案刚刚出现。在此,我们综述肾脏再生领域的主要发现,主要关注从人类多能干细胞生产肾细胞的逐步方案的开发以及肾脏生物工程的最新进展(即脱细胞肾脏支架和生物打印)。利用肾源性诱导多能干细胞重新细胞化生成类肾三维结构的可能性可能为按需开发功能性肾脏移植物提供新途径。
