Abstract There are numerous experimental studies in the literature regarding skin storage and preservation. These studies are difficult to interpret due to the variety of storage techniques utilized and the number of different animal species used as skin donors. This study utilized a single cold storage protocol to test the effect of species variation on skin graft viability. Donor skin was obtained from five animal species and human surgical panniculectomy specimens. The skin was stored in modified Roswell Park Memorial Institute (RPMI) 1640 tissue culture media at 4 degrees C. Stored skin was transplanted to surgically created defects on athymic (nude) mice after specific storage intervals. Ten days after transplantation, the grafts were examined by gross and microscopic techniques. The viability of mouse, rat, and dog skin was significantly different from human skin, while stored rabbit and pig skin were similar to human skin. These results demonstrate the difficulty of applying the data of skin storage studies from nonhuman species to clinical practice. The data indicate that rabbit and pig skin may be used in laboratory studies of skin preservation at 4 degrees C with a strong likelihood that the results may be of clinical relevance in predicting the behavior of human skin under similar storage conditions.
