Abstract
A process for preserving cultured epidermal sheets by incubating the sheets at room temperature in media with a glycerol or dimethylsulfoxide cryopreservant for a predetermined period of time and then freezing the cultured sheets. The cooling gradient is characterized as having a lower initial rate of cooling followed by a higher rate of cooling.
