ns for disease progression and prognosis. Findings from the pituitary tumor study generally support the cancer stem cell hypothesis, suggesting that similar mechanisms may be involved in the generation of both malignant and benign tumors," said Keith L. Black, M.D., chairman of the Department of Neurosurgery at Cedars-Sinai.

"Confirmation of the existence of stem-like cells in benign tumors is intriguing," said Yu, "but many questions remain to be answered, particularly in defining the molecular mechanisms involved. We need to find out if there is any relationship between tumor stem cells and normal pituitary stem cells, and how stem cells from benign tumors are different from and similar to those of malignant tumors."
