Outline of Final Research Achievements |
The aim of our research was to reveal the way of isolation culture and the function of pituitary tumor stem cells. 60 cases non-functional pituitary adenomas were frozen and stored after the dissociation process, allowed the establishing uniform conditions for measurement of the sample. It was found that more than 70% of non- functional pituitary adenomas secreted two or more anterior pituitary hormones. Flow cytometric analyzes of nestin, a stem cell marker, was found to be expressed in non- functional pituitary adenoma cells. Multi- secretory function of the pituitary adenoma cells has also been suggested the possibility as a stem cell. In the future, by examining the mechanism of multi- secretory function of the pituitary tumor cells, a clue to tumor stem cells might be found.
