 CRH immunoreactive cells are abundant in the chicks’ PVN. (a), hematoxylin and eosin staining of the chicken brain section indicating the anatomical location of the PVN, lateral ventricle (LV), third ventricle (VIII) and the hippocampus (HP), at position A 7.6 (Kuenzel and Masson, 1998). (b), Immunofluorescent staining of frozen coronal brain sections of the hypothalamus area of 3-day-old chick, immunostained with anti-CRH antibody and DAPI. (c), Magnification of the hypothalamic PVN are showing the abundance of CRH immunoreactive cells.
