In addition to their use in cancer treatment, hematopoietic stem cell transfers are used to treat patients with diseases of the hematopoietic system, such as aplastic anemia, hemoglobin disorders, and immune deficiencies. Epithelial stem cells have also found clinical application in the form of skin grafts that are used to treat patients with burns, wounds, and ulcers. One approach to these procedures is to culture epidermal skin cells to form an epithelial sheet, which can then be transferred to the patient.
