[Wound epithelialization in rats depending on the quantity and orientation of microautotransplants]

Patches of autoskin (0.5 x 1.0 mm) were grafted on a full-thickness rat back skin wound (5.4 cm2). As a result of "island" epithelialization from microautotransplants (MATR), the skin defect underwent repair. It is shown that the advance of the wound re-epithelialization did not depend on MATR number and their orientation in relation to the wound surface. The use of MATR allows to restore the skin defect with the plastic coefficient 1:100. This reduces the deficiency of donor skin at extensive burns.
