AbstractThis study was designed to examine the effect of the storage configuration of skin and the ratio of tissue-to-storage medium on the viability of skin stored under refrigeration. Human skin specimens were stored in four physical configurations in RPMI 1640 tissue culture media at 4 degrees C. Skin was transferred to surgically created defects on nude mice after specific storage intervals. Grafts were examined grossly and microscopically after ten days. In the rolled configuration, on storage day 15, the viability of the outside of the roll was significantly better than the inside (P less than 0.01). The graft viability of the outside of the skin rolls was similar for both tissue-to-media ratios as well as for both free-floating configurations (P = 0.27). These findings suggest the optimum cold storage configuration is free floating, and 300 cm2/100 mL is an appropriate skin surface area to volume media ratio. This proportion of tissue to media is in agreement with the minimum ratio currently recommended by the Skin Council of the American Association of Tissue Banks.
