The distribution and morphological features of ACTH1-39 immunoreactive neurofibers were studied on 6 human fetus (36-40 weeks of fetal life) . ACTH1-39 immunoreactive cell bodies were found in the infundibular nucleus and adjacent lateral regions of the hypothalamus. The cell bodies were elliptic or round,and the processes were short, thick-pyramidal in shape. ACTH1-39 immunoreactive neurons were found in the supraoptic nucleus. The majority of these neurons were located in the dorso-medial part of the dors...
