SUBMUCOSA AS GROWTH SUBSTRATE FOR CELL

摘要

PROBLEM TO BE SOLVED: To provide a cell culture method which promotes proliferation and tissue differentiation of eukaryotic cells in vitro.

SOLUTION: Cell growth of cell/tissue culture is improved by using submucosal tissue of warm-blooded vertebrate as the substrate of in vitro cell/tissue proliferation. A collagen substrate environment similar to an environment found in vivo is provided to cells in vitro by a submucosal tissue cell growth substrate. The submucosal tissue promotes proliferation and differentiation of eukaryotic cells when the cells are brought into contact with submucosal tissue under conditions inducive to cell proliferation.
