Title:
PRODUCTION METHOD FOR CELL MASS INCLUDING NEURAL CELLS/TISSUE AND NON-NEURAL EPITHELIAL TISSUE, AND CELL MASS FROM SAME
Document Type and Number:
WIPO Patent Application WO/2019/103125
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a means of efficiently producing, from pluripotent stem cells, a cell mass that includes neural cells/tissue and non-neural epithelial tissue. Provided is a production method for a cell mass that includes 1) neural cells or neural tissue, and 2) non-neural epithelial tissue, said method comprising steps (1) and (2): (1) a first step in which pluripotent stem cells are suspension-cultured in the presence of a Wnt-signalling pathway inhibitor, and a cell aggregation is formed; and (2) a second step in which the aggregate obtained in the first step is suspension-cultured in the presence of a BMP-signalling pathway activator, and a cell mass that includes 1) neural cells/tissue, and 2) non-neural epithelial tissue, is obtained.
