Cells derived from debrided burn tissue may be useful for tissue engineering
Date:7/11/2012

Putnam Valley, NY. (July 11, 2012) A research team in the Netherlands has found that cells from burn eschar, the non-viable tissue remaining after burn injury and normally removed to prevent infection, can be a source of mesenchymal cells that may be used for tissue engineering. Their study compared the efficacy of those cells to adipose (fat)-derived stem cells and dermal fibroblasts in conforming to multipotent mesenchymal stromal cell (MSC) criteria.

Their study is published in the current issue of Cell Transplantation (21:5), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/.

"In this study we used mouse models to investigate whether eschar-derived cells fulfill all the criteria for multipotent mesenchymal stromal cells as formulated by the International Society for Cellular Therapy (ISCT)," said study co-author Dr. Magda M.W. Ulrich of the Association of Dutch Burn Centres, The Netherlands. "The study also assessed the differentiation potential of MSCs isolated from normal skin tissue and adipose tissue and compared them to cells derived from burn eschar."

According to the researchers, advances in burn treatment have meant that the percentage of patients surviving severe burn injuries is increasing. This escalating survival rate has also increased the number of people who are left with burn scars, which lead to functional problems with the skin, such as contracture, and the social and psychological aspects of disfigurement.

Tissue engineering to rebuild the skin is the most promising approach to solving these problems. However, two problems arise with tissue engineering the source of the cells and the design of the scaffold aimed at creating a microenvironment to guide cells toward tissue regeneration.

"The choice of cells for skin tissue engineering is vital to the outcome of the healing process," said Dr. Ulrich. "This study used mouse model
