Abstract

Immunohistochemistry and RT-PCR of basic fibroblast growth factor (bFGF) and one of its receptors (FGFR-I) were performed in pituitary adenomas. Sixty percent of pituitary adenomas showed strong or moderate immunoreactivity to bFGF. The immunoreactivity for FGFR-I in tumor tissues showed positive correlation to that for bFGF (χ² = 6.176, P = 0.0456). Basic FGF-positive cells consisted of pituitary adenoma cells as well as folliculostellate cells and, their distribution was heterogeneous. Expressions of bFGF and FGFR-I were not related to cell proliferation of pituitary adenomas or hormones produced, suggesting that bFGF plays some role other than progression of pituitary adenomas.
