A combined immunocytochemical and morphometric study on the development of the prolactin (PRL) cells of the annual cyprinodont Cynolebias whitei, transferred as newly hatched larvae to water with different salinities and/or Ca2+-concentrations, was carried out. The percentage of the pituitary volume occupied by PRL cells and the affinity of PRL cells for(More)
In the developing pituitary gland of embryos of the annual fish Cynolebias whitei and the medaka, Oryzias latipes, prolactin cells have been identified before hatching by means of a light-microscopic immunocytochemical method with antiserum against ovine prolactin. At the time of hatching, changes in the intensity of the immunoperoxidase staining occur.(More)
The pituitary gland of Latimeria chalumnae is situated rostroventral to the telencephalon. The hollow pituitary stalk is bent forward and is ventrally connected to a saccus-vasculosus-like organ, rostrally to a neurointermediate lobe. The infundibular lumen protrudes far into the neurohypophysial lobules. The elongated principal part (pars cerebralis) of(More)
Non-neoplastic pituitary glands of 12 age-groups of 10 male Wistar rats (subpopulation 1) and of 228 rats with age-related disorders (population 2) were studied. For subpopulation 1 a positive correlation was found between body weight, pars distalis volume and total prolactin (PRL)-cell volume. These values increased during the first half of the life span(More)
