To change the skin identity investigators propose to take skin cells from a person's own sole or palm (these are called "autologous skin fibroblasts"), multiply them in the lab, inject the cells (now called a "graft") back into the same person but at a different site of skin like the buttock, and then eventually remove the injected cells to see if they caused the skin to change.
Investigators hope that information from this study will help with problems like skin break-down in patients with amputations and prosthetics. The skin at their stump was not meant to withstand the pressure and friction of prosthetics and this study is the first step in trying to convert stump skin to palm/sole-like skin.

Experimental: autologous skin fibroblasts
we are comparing 3 injection sites in the same individual
Biological: autologous skin fibroblasts
- Cytoplasmic size increase [ Time Frame: 6 months ]Volar keratinocytes have larger area of the cytoplasm. We will quantitate the area of cytoplasm of non-volar keratinocytes to see if they increase selectively with volar fibroblasts as opposed to other fibroblasts injections or vehicle. The change in the area of cytoplasm of non-volar keratinocytes will be measured. The units of this measurement are a ratio of cytoplasmic area to total cellular area as a control.
- Fibrometer reading [ Time Frame: 6 months ]Fibrometers measure the firmness of the skin. We will measure all sites to see if the area injected with volar fibroblasts is more firm. The units of measurement is in Newtons.
