part_of part of part of overlaps capable of expresses expresses tanycyte secretory epithelial cell beta1-tanycyte A type of tanycyte located in ventral part of the lateral wall of the third ventricle and in the lateral infundibular recess of the brain. This tanycyte has an elongated morphology with multiple microvilli extending into the median eminence. This type of tanycyte expresses FGF receptors 1 and 2, is in contact with GnRH neurons, and is involved in the release of gonadotropin-releasing hormone (GnRH). vmARH tanycyte gonadotropin secretion fibroblast growth factor 1 fibroblast growth factor 2 median eminence of neurohypophysis infundibular recess of 3rd ventricle
