| Research Abstract |
The current research aimed to indentify tissue specific stem cell of the vocal fold using SP cells. However, although SP cell could be separated, collection and culture of the cells turned out to be technically difficult. Then it was attempted to pick up SP cells during wound healing of the vocal folds using rat models and ABCG antibody. The results showed increased expression of SP cells during early wound healing period. Characterization of the cells using surface markers is under way. The third project aimed to examine regenerative effects of stem cells for the vocal fold. Bone marrow derived mesenchymal stem cells were used for regeneration of scarred vocal folds in a canine model. The results were encouraging with positive effects on histology and function of the regenerated vocal folds.
