<p>Coating materials for biological tissues which make it possible to preserve biological tissues over a long period of time; coated biological tissues with the use of the materials; and a method of coating biological tissues. A biological tissue is coated by using a coating material which contains at least a hydrogel-forming polymer and shows heat-reversible sol/gel transfer, i.e., being in the state of a sol at lower temperatures and setting to gel at higher temperatures. Thus a ratio A2/A0 (wherein A0 represents the cell survival ratio of the biological tissue immediately before the coating, and A2 represents the cell survival ratio of the biological tissue 2 days after the coating) of 20% or more can be easily established.</p> |
