The treatment of donor sites with cultured epithelial grafts

In a significant number of elderly patients, the healing of split skin donor sites can be delayed. The cultured allogenic epithelial graft (CAG) has been reported to heal leg ulcers. The mechanism of action may be to improve the healing environment and thus stimulate the host skin cells. A clinical trial was undertaken to compare the healing rate of the donor sites of elderly patients using CAGs and two commercially available dressings. Compared to Jelonet, CAGs (p = 0.008) and OpSite (p = 0.013) significantly reduced the number of patients with delayed healing. There was no significant difference between CAGs and the occlusive dressing, OpSite.
