摘要：
Methods and apparatus are provided for affecting an appearance of skin by harvesting small portions of tissue from a donor (first) site and applying them at a recipient (second) site. A plurality of micrografts can be formed from a piece of graft tissue and attached to a dressing material. The dressing material can then be expanded to increase a separation distance between the micrografts, and the dressing material having spacedapart micrografts attached thereto can be applied to a prepared recipient site. An apparatus can be provided that expands the dressing material using a pressurized fluid. A further method can include providing a suspension of small portions of graft tissue in a solution. The solution can be injected into blisters formed at a recipient (second) site and the tissue portions allowed to attach and proliferate. A method and apparatus can also be provided for forming corresponding blisters at a donor site and at a recipient site. The raised (removed) portions of the blisters can be removed and attached to a dressing material, and the portions from the donor (first) site can be placed onto the exposed blister areas at the recipient site.
