Coating material for living organism tissue, coated product from living organism tissue and method of coating living organism material

摘要

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.
