Outline of Final Research Achievements

Part of the slow-cycling cells exhibit pluripotency, and they are thought to be tissue specific stem cells in some organs. In this study, we investigated the distributions and characteristics of slow cycling cells in rat vocal folds.
We applied double labeling technique to detect the distribution of slow cycling cells, and most slow cycling cells were detected in the basal layer of the epithelium. Further, histological investigation revealed various phenotypes in a relatively undifferentiated condition of slow cycling cells.
A time-dependent reduction of slow-cycling cells was observed in injured vocal folds, and they are suspected to contribute to the tissue repair of the injured VFs.
