Outline of Final Research Achievements |
The anterior pituitary gland is composed of five types of hormone-producing cells and folliculostellate cells, which do not produce hormones. Folliculostellate cells encircle hormone-producing cells by cytoplasmic processes and control the functions of these cells via humoral factors. However, the folliculostellate cell-mediated cell-to-cell interactions are not fully understood. In this study, we found several bioactive substances including growth factors, cytokines, and vitamin, which were produced in folliculostellate cells. Furthermore, we showed that these molecules play important roles in the pituitary development, tissue formation, and hormone secretion. The data obtained from this project suggested that these molecules function as novel paracrine signaling molecules in the anterior pituitary gland.
