ABSTRACT:
The viability of cohesive sheets of cultured epithelial cells such as keratinocytes used as wound dressings is maintained or improved by storage at a temperature within the range of 8.degree.-25.degree. C., preferably 13.degree.-23.degree. C., for periods greater than 8 hours, preferably up to 26 hours. This method and the resulting product permits a significant increase in the shipping radius of cultured dressings manufactured in a central facility, and increases flexibility in scheduling of shipments and surgical procedures.
