Tissue Engineering in Wound Healing Therapy by Using Chitosan and Stem Cells

Abstract

Skin wounds are considered as the most critical, and widespread problems due to the high rate of accidents or burn worldwide. Full-thickness skin loss could be chronic or acute wounds, which found difficulty in medical treatment, because of taking a long time in healing. Therefore, exposure to the infection, which delays the healing process and causing disordered healing, ends with distortion or incomplete closure, which might lead to a fatal complication. Thus, the need for skin grafting is a necessary and critical decision although its side effects and rejection possibilities. This review put a spotlight on one of the latest therapeutic techniques in regenerative medicine "tissue engineering". It is an up-to-dates field in applications of stem cells and cells culture to replace the traditional tissue or organs transplantation techniques. We discussed the skin organ scaffolding as a simple example of tissue engineering applications in accelerating wound healing using stem cells cultured with chitosan scaffold. The latter is characterized by several medical properties especially in skin regeneration, for fabrication of artificial skin, which mimics the natural skin tissue and applying it in chronic or acute wounds therapy.
