title: A comparison of storage viability of nonmeshed and meshed skin at 4 degrees C.
abstract: Skin stored in nutrient medium at 4 degrees C produces acceptable short-term viability. This study compared the storage viability of nonmeshed v meshed skin stored at 4 degrees C in nutrient medium. Skin specimens from six human donors were stored for up to 35 days in RPMI 1640 tissue culture medium at 4 degrees C. Skin specimens (1 cm in diameter) were transplanted to surgically created defects on the thorax of nude mice at fixed intervals during the storage period. Gross and microscopic techniques were used to determine the graft viability at 10 days postgraft. Skin was divided into two storage groups as nonmeshed or meshed 1.5/1. The storage configuration was free-floating, 10 cm x 2 cm sheet grafts. The ratio of skin surface area to volume medium was 300 cm2/100 mL. There was no significant difference between the viability of the nonmeshed group compared to the meshed group. Prior meshing of human allograft does not adversely affect the viability of banked skin. Therefore, skin can be stored in a meshed configuration. This eliminates operating room time spent preparing allograft for application, which is cost-effective.
