| Outline of Final Research Achievements |
Recent study revealed that SOX2 protein was transcriptional factor that contributed a development of pituitary gland. Therefore, we speculated that SOX2 positive cells play an important role in endocrinologic phenotypes of pituitary adenoma.
In this study, we show that the pituitary adenoma contains a small population of SOX2 positive cells that, is preferentially present in functioning adenoma. But, SOX2 positive cell is not hormone producing cells.
We hypothesized that SOX2 positive cells in pituitary adenoma also maintain the tumor, that these cell is present as a reserve of hormone producing cells or flicullostellate cells. To elucidate the role of SOX2 positive cells in pituitary adenoma, further study is necessary.
