He moderately stained neurons from the medial and lateral habenular nuclei(Fig 1J, MHb, LHb) within the epithalamus. Additional strongly stained neurons were discovered within the mediodorsal, lateral dorsal, and ventral lateral thalamic nuclei (Fig 1J, MD, LD, VL) also as the reuniens thalamic nucleus(Fig 1J, Re). Scattered lightly to moderately stained neurons were located in the location of your globus pallidus(Fig 1J, GP). The cells on the lateral hypothalamic nucleus(Fig 1J, LH; Fig 2K) exhibited moderate to powerful staining and have been far more densely arrayed. 3.three Prosencephalon Starting at the forebrain level the distribution of TCF7L2-labeled cells integrated the robustly stained neurons from the subfornical organ(Fig 1K, SFO; Fig 2L), those with the lateral preoptic location(Fig 1K, LPO; Fig 3A), the medial preoptic nucleus(Fig 1K, MPO; Fig 3B) and smaller nuclei which includes the nucleus of horizontal limb of diagonal band(Fig 1K, DBh),J Chem Neuroanat. Author manuscript; available in PMC 2013 October 01.NIH-PA Author Manuscript NIH-PA Author Manuscript NIH-PA Author ManuscriptWeaver et al.Pageaccumbens nucleus(Fig 1K, Acb) and magnocellular preoptic nucleus(Fig 1K, MCPO). In the remaining levels, intensely labeled TCF7L2 cells composed several layers lining the ventricular and subventricular zones in the lateral ganglionic eminence(Fig 1L, LG) which kind the septal(Fig 1L, Sn, Fig PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21237502 3C) and striatal neuroepithelium. Though present within the exact same zones on the lateral ganglionic eminence forming cortical neuroepithelium(Fig 1L, Cn) and medial ganglionic eminence forming the striatal neuroepithelium(Fig 1L, Mge), the cells of this layer exhibited significantly less intense labeling for TCF7L2. The strongest expression of TCF7L2 inside the neuroepithelium was located between E14 and E18.five. A couple of moderately stained and scattered cells had been identified inside the medial septal nucleus(Fig 1L, MS). three.4 ParaDAPI (dihydrochloride) sagittal Planes Parasagittal sections supplied further insight for the distribution and expression of TCF7L2. The robust staining of the dense collection of neurons shown in Fig 3D-E which compose the parafascicular(PF), mediodorsal(MD), subparafascicular(SPF), anteriomedial(AM), ventral medial(VM), ventral posterior medial(VPM), and reticular(Ret) thalamic nuclei at the same time because the unstained fibers from the fasciculus retroflexus(fr) above and also the cells from the zona incerta(ZI) under contributed for the well-defined demarcation of thalamic boundaries in the pretectum above along with the hypothalamus under. This sagittal section also illustrates labeled TCF7L2 cells in the tectum such as moderately labeled cells on the pretectum(Fig 3D-E, Ptec), periaqueductal gray(Fig 3D, PAG), dorsomedial periaqueductal gray(Fig 3D, DMPAG) and superior colliculus(Fig 3D, SC) as well as cells on the epithalamus such as posterior commissural(computer), precommissural(PrC) along with the medial and lateral habenular nuclei(Fig 3E, MHb, LHb) along with the ventrolateral periaqueductal gray region(Fig 3D, VLPAG). In Fig 3F, moving subthalamically a clear profile of robust TCF7L2 labeled cells can be noticed composing the ventromedial hypothalamic nucleus(VMH) near the pituitary(P) within this parasagittal section close to the midline. Within the brain stem adjacent to the thalamus the reticular cells with the pons had been located to exhibit a strong immunoreactive label for TCF7L2(Fig 3F, RFp). This was located to become characteristic on the reticular cells throughout the brain stem like those reticular cells in the medulla(Fig 3F, RFm) along with the gigantocellular r.
