Tissue stem cells include hematopoietic stem cells, mesenchymal stem cells and epidermal stem cells, and these cells are differentiated into specific cell types.
Hematopoietic stem cells
Hematopoietic stem cells are the source of blood cells in the bone marrow. They are used in the treatment of malignant lymphomas and multiple myeloma.
Epidermal stem cells
Epidermal stem cells are tissue stem cells that exist in the epidermis and have the ability to form epidermal tissue. Recently they have been used as cultured epidermal sheets to treat severe burns and other conditions.
