CULTURE METHOD AND CELL MASS

摘要

The present invention is a culture method for culturing a population consisting of two or more cells including stem-cell-derived cells and mesenchymal cells in an indentation (10). Stem-cell-derived cells are cells obtained by differentiating stem cells in vitro. Such cells are one or more types of cell selected from the group consisting of endodermal cells, ectodermal cells, and mesodermal cells. The population is cultured in an indentation (10) together with vascular cells or secretory components. The indentation (10) has a space in which the cells can move. The volume of the space is taken to be V mm3. The number of mesenchymal cells seeded in the space is taken to be N. At this time, V is 400 or less. Furthermore, N/V is from 35 to 3000.
