Hypertrophic scars result from abnormal healing of severe burns, and are characterized by loss of the original structure and function of the skin. Transplantation of autologous split skin is the preferred treatment after scar excision; however, there will be some unavoidable degree of contraction within the grafts. To our knowledge, it is very rare that bone marrow-derived mesenchymal stem cells (BM-MSCs) have been used for the treatment of skin-graft contraction. However, in our clinics, we found that during a 2-year follow-up analysis, areas treated with autologous BM-MSCs combined with transplantation of split skin were less likely to have contraction of the skin grafts than areas treated with skin grafts alone. This result indicates that BM-MSCs may be a potential and promising treatment to prevent contraction of skin grafts.
