Introduction: The anterior pituitary lobe is a key endocrine tissue composed of five types of endocrine-cells and non-hormonal cells. Among non-endocrine-cells, Sox2-expressing cells exist as stem/progenitor cells and play a role in the regeneration of endocrine-cells in the adult pituitary. Recently, we have reported that transcription factors, Prop1, Prrx1 and Prrx2, are expressed in the pituitary stem/progenitor cells and these cells cont...

Introduction: FSH and LH are glycoprotein hormones and are synthesized in the anterior lobe of the pituitary gland and plays critical roles for maintenance of vital functions. FSH and LH are secreted to pituitary capillary vessel and exert their effects on reproductive organs of both sexes to stimulate steroidogenesis and gametogenesis. Secretion of FSH and LH is controlled mainly by GnRH released from hypothalamus. Many investigations on secretion of FSH and LH were performed...
