Human corticoliberin hypothalamic neuroglandular system: comparative immunocytochemical study with anti-rat and anti-ovine corticotropin-releasing factor sera in the early stages of development.
1987
Abstract Development of the paraventriculo-infundibular corticoliberin system was studied by immunocytochemical analysis of human hypothalamic sections using antisera raised against rat or ovine corticotropin-releasing factor (CRF). This comparative study confirms the presence of a significant number of CRF-immunoreactive fibers in the median eminence during the 16th week of fetal development and suggests they may appear as early as the 14th week. Some hypothalamic peri- and paraventricular neurons, observed from the 12th week, are rat-CRF-immunoreactive but not ovine CRF-immunoreactive. There appears to be chronological differences concerning the ability of the two antisera to recognize hypothalamic structures during the early stage of development.
