Measure
MKTP With Surgical Blade
The investigator harvested skin from the donor site and skin from the recipient site using a surgical blade in the first arm of the study. MKTP with Surgical blade: In this procedure, the donor skin will be harvested with a surgical blade and the donor skin will be dissociated
MKTP With Negative Pressure Instrument
Blister grafting technique with dissociation of the cells was performed in the second arm of the study. MKTP with Negative Pressure Instrument: In this procedure, the investigator uses a negative pressure instrument to create a few blisters on the donor skin and use the blisters for grafting after cell dissociation.
Suction Blister Grafting Without Cell Dissociation
In this arm, transplanting the blisters without dissociation of the cells will be conducted. Suction blister grafting without cell dissociation: In this procedure, an automated suction blister device will be used to create micro domes and these micro domes will be used directly for grafting without dissociation.
