Ki-67 staining in the hypothalamus. The larger figure in this panel shows the anterior and inferior boundaries of the hypothalamus in a parasagittal view. (A–D) are magnified views of the boxes indicated in the larger figure. Arrows point to nuclei stained with Ki-67 that were observed primarily near the pial surface of the hypothalamus. Cell nuclei appear stained by hematoxylin. (ovlt), organum vasculosum lamina terminalis; (poa), pre-optic area; (sc), supra-chiasmatic nucleus zone; (oc), optic chiasm; (me), median eminence; (mb), mammillary body. Scale bars: larger figure = 2,000 μm; (A–D) = 100 μm.
