Paper commentary by Stuart P. Atkinson
Tissue resident adult stem cells, such as mesenchymal stem cells (MSCs) or adipose-derived stem cells (ASCs), have previously demonstrated a capacity to repair extensively injured tissues (Picinich et al, Horwitz and Dominici). However, major traumatic injuries such as large surface area burns, which constitute 5%–10% of military casualties, limit the availability of autologous stem cell populations for wound repair and such injuries also require extensive reconstruction. The process of wound debridement; the medical removal of a patient's dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue, typically involves the removal of subcutaneous layers and associated tissue structures, including portions of intact hypodermal adipose tissue. This led the group of Robert J. Christy at the United States Army Institute of Surgical Research, Fort Sam Houston, Texas, USA to investigate the potential of debrided skin to be a source of viable autologous stem cells for use in wound treatments. Their report (Natesan et al) is published in the August Edition of Stem Cells.
