abstract:
A method for the preservation of in vitro expanded epithelial sheets which comprises the incubation of said sheets in a cryopreserving solution characterized by lack of volume increase at the liquid-solid phase transition. The cryopreserving solutions comprise: a) polyethylene glycols having molecular weight not higher than 20 KD; b) at least one cross-linking agent selected from polyols, polyamines, mono- or oligosaccharides, polyethyleneglycols having molecular weight lower than 1 KD .
