| Outline of Final Research Achievements |
A whole-mount staining method was employed to visualize three-dimensional structure of human sweat gland that is unbranched coiled tubule consisting mainly of secretory portion and duct. We found that i) ductal tubule was spatially embraced in secretory tubule; ii) ductal tubule was occasionally bent, while secretory tubule was frequently bent and formed a self-entangled coiled structure; iii) secretory portion was surrounded by myoepithelial cells longitudinally elongated along entangled secretory tubules; iv) nerve fibers wrapped around secretory tubules, but not ductal tubules. These results suggest that multiple myoepithelial cells of sweat gland synchronously contract their secretory portion following innervations.
