Study Description
Brief Summary:
This research is being done to determine if investigators can change skin from one type to another. Specifically, investigators are interested in making normal skin into the thicker skin found on our palms and soles.

Condition or disease Intervention/treatment Phase
Wounds and Injuries Biological: autologous skin fibroblasts Phase 1

Detailed Description:

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.
