Stimulation of FSH release by erythroid differentiation factor (EDF)
Biochemical and Biophysical Research Communications
|August 14, 1987
Abstract:
The action of erythroid differentiation factor (EDF) on primary culture of rat anterior pituitary cells was examined. EDF stimulates FSH secretion in a dose dependent manner but not of LH secretion. ED50 of EDF for FSH secretion was 5 X 10(-10) M, while ED50 of LHRH for FSH secretion was 5 X 10(-9) M. These data indicate that EDF is a potent agonist for FSH secretion and the biological activity of EDF on anterior pituitary seems to be identical as that of FSH releasing protein (FRP).
