Regenerative Medicine: Novel Approach in Burn Wound Healing

Context Burn wounds of the skin require a long period to healing, which very often is incomplete, with functional and esthetic consequences for the patients. Stem cells in the traumatized tissue represent the promoters of the healing process and are a primary focus for regenerative medicine, which aims to find and use the triggers for the activation of stem cells of sin tissue. Evidence Acquisition At present, tissue engineering, composite epithelial autografts, multipotent stem cells and combined gene delivery with stem cell therapy are the approaches used in regenerative medicine. Alongside, the development of 3D scaffolds or matrices is a promising adjunct, as studies investigate the multiple uses of these supports for wound repair. Results Application of cells to the burn wound could be performed, either by the bedside, as a non-invasive procedure, or in the operating room, with the use of a matrix, scaffold or dermal substitute. Cell spraying, although under use in clinical setting, is not yet supported by conclusive data. Magnetic resonance imaging, optical imaging and positron emission tomography are currently used to assess the viability and location of stem cells, after transplantation. Conclusions Stem cell therapies in wound care may lessen the morbidities associated with wound healing. An ideal method for the effective administration of stem cells for burn patients has not yet been elucidated. Further comparison of the local and systemic effects in burn patients, associated with each route of stem cell delivery, needs to be performed
