A cell or tissue-culturing carrier which can effectively regenerate an intended
a cell or tissue, while suppressing an excessive growth of fibroblasts, and a method
of culturing a cell or tissue by using the above carrier, the cell or tissue-culturing
carrier wherein fibroblasts showing substantially no growing property in a gel
based on the hydrogel-forming polymer, is constituted by using a hydrogel-forming
polymer; an aqueous solution of which shows a thermo-reversible sol-gel transition
such that it assumes a sol state at a lower temperature and assumes a gel state
at a higher temperature.
