Developmental pattern of reelinmRNA expression in the diencephalon and hypothalamus. A, B, Photomicrographs illustrating two different rostrocaudal levels at E14, showing prominent reelin expression in the amygdala (Amg), medial forebrain bundle (mfb), entopeduncular area (EP), reticular nucleus/zona incerta (RT/ZI), ventral lateral geniculate nucleus (VLG), and anterior hypothalamic nucleus (AH). C, At E16, reelin is expressed in the VLG, zona limitans intrathalamica (zli), and paraventricular hypothalamic nucleus (PA); D, At E18,reelin mRNA is expressed in the medial habenula (MHb), VLG, zona limitans intrathalamica/external medullary lamina (zli/eml), and PA; lower expression levels are detected in several other nuclei.E, reelin expression in the pretectum at P0. APT, Anterior pretectal nucleus; CPu, caudate-putamen; DT, dorsal thalamus; ic, internal capsule; LH, lateral hypothalamus;LHb, lateral habenula; lo, lateral olfactory tract; lv, lateral ventricle;OPT, olivary pretectal nucleus; pc, posterior commissure; PrC, nuclei of the posterior commissure; PV, paraventricular thalamic nucleus;RCH, retrochiasmatic area; VT, ventral thalamus; 3v, third ventricle. Scale bar, 250 μm.
