Preservation of human skin: a study of two media using the athymic (nude) mouse model

This study is part of an ongoing attempt to define the optimal conditions for short-term storage of viable human skin for auto- or homotransplantation. Roswell Park Memorial Institute 1640 (RPMI) media was more convenient to use than Eagle's Minimum Essential Medium with HEPES buffer (MEM-H) but functional skin viability was not statistically different in the two media. MEM without HEPES buffer did not preserve human skin at 20 days storage. The athymic (nude) mouse provides an excellent in vivo test of stored human skin functional viability.
