Abstract:
Kidney is an essential organ in human body with multiple physiological functions. However, there is 10 % population worldwide with renal disease. It is urgent to generate a model which is more similar with kidney at structural and functional level to study renal disease. The rise of in vitro differentiation technology from pluripotent stem cells gives regeneration medicine and precise medicine new energy. This study mimics kidney development in vitro by inducing human pluripotent stem cells including embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) into kidney progenitor cells, and further forming nephrons, which is the structure and function unit in kidney. Human pluripotent stem cells were differentiated into primitive streak through activating WNT pathway while inhibiting TGF-(B signaling. Afterward, the primitive streak spontaneously differentiated into intermediate mesoderm. Then, we induced intermediate mesoderm cells into kidney progenitor cells through FGF pathway. The FACS analysis data indicated kidney progenitor cells were up to 51. 5%-61. 9% in total cell population. Immuno-stai-ning results showed these structures contained podocytes of glomerulus, proximal tubule, and distal tubule. This kidney differentiation protocol is stable, high-efficient, and well repeatable. This research provides a novel platform for early human kidney development study, kidney disease modeling, and drug screening.
