Abstract
A cell culture growth substrate comprising submucosal tissue of a warm-blooded vertebrate and a method for culturing eukaryotic cells are described. Submucosal tissue used in accordance with the present invention supports the proliferation and differentiation of eukaryotic cells when said cells are contacted with submucosal tissue under conditions conducive to cell proliferation.
Claims5
A composition for supporting the growth of a cell population, said composition comprising
- enzymatically digested submucosal tissue of a warm-blooded vertebrate;
- and
- added nutrients to support the growth of said cell population in vitro, wherein the nutrients are combined with a solution of the enzymatically digested submucosal tissue and the resulting solution is gellable to form a solid or semi-solid matrix.
A composition for supporting the growth of a cell population, said composition comprising
- culture-ware coated with a matrix comprising submucosal tissue that has been enzymatically digested and then gelled.
