| Outline of Final Research Achievements |
In this study, we investigated distribution and differentiation potential of nestin-expressing cells in normal skin, cutaneous tumor and wounded skin. The nestin-expressing spindle cells and pericytes are distributed in dermal papilla, as well as dermis surrounding cutaneous epithelial tumor and wounded skin. In addition, we found that keratinocytes in outer root sheath cells, keratoacanthoma and wounded skin are daughter cells of nestin-expressing cells. These findings imply that nestin-expressing spindle cells contribute to keratinocyte proliferation, and some of keratinocytes in hair follicle and cutaneous epithelial tumors consist of daughter cells of the neural crest stem cells.
