Abstract

The invention discloses a serum-free induction medium and an induction method for differentiating an iPS (induced pluripotent stem) cell into an endodermal progenitor cell. The serum-free induction medium comprises a first-stage medium, a second-stage medium and a third-stage medium. According to the serum-free induction medium and the induction method for differentiating the iPS cell into the endodermal progenitor cell, the iPS cell can be directionally induced to be differentiated into the endodermal progenitor cell, thereby providing a technical support for each iPS cell induced to be differentiated into an adult. In addition, no serum is used by the serum-free induction medium and the induction method, so that risks brought by animal-derived pathogens are effectively avoided, and the clinical application safety is improved.

Description

technical field [0001] The invention relates to the field of tissue engineering, in particular to a serum-free induction medium and an induction method for iPS cells to differentiate into endoderm progenitor cells. Background technique [0002] Tissue engineering has been a research hotspot in recent years, but it is difficult for seed cells to be cultured and expanded on a large scale in vitro, and the source of seed cells hinders the development of tissue engineering. The sources of autologous seed cells are limited, allogeneic seed cells have rejection reactions, and embryonic stem cells have ethical issues. Therefore, urine cells are collected from urine and induced into iPS cells (induced pluripotent stem cells). iPS cells Re-induction into individual adult cells can solve the problem of seed source for tissue engineering. Obtaining cells from urine is convenient and quick, without trauma, and has a wide range of sources. [0003] At present, the methods of inducing t...
