摘要:
PROBLEM TO BE SOLVED: To provide a method of preparing mature retinal ganglion cells by differentiation of stem cells into the retinal ganglion cells.SOLUTION: A method of preparing mature retinal ganglion cells by differentiation of stem cells into the mature retinal ganglion cells comprises: (a) culturing retinal progenitor cells in a medium comprising an IGF1R (insulin-like growth factor-1 receptor) activator and a Wnt signaling pathway activator to differentiate them into immature retinal ganglion cells; and (b) culturing the immature retinal ganglion cells in a medium not comprising the Wnt signaling pathway activator included in the medium of step (a).SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】幹細胞を網膜神経節細胞に分化させて成熟網膜神経節細胞を製造する方法の提供。【解決手段】(a)網膜前駆細胞をIGF1R(insulin-like growth factor-1 receptor)活性剤及びWntシグナル伝達経路活性剤を含む培地で培養して未成熟網膜神経節細胞に分化させる段階と、(b)未成熟網膜神経節細胞を(a)段階の培地のWntシグナル伝達経路活性剤を含まない培地中で培養する段階と、を含む幹細胞を成熟網膜神経節細胞に分化させ、成熟網膜神経節細胞を製造する方法。【選択図】図1
