He moderately stained neurons of your medial and lateral habenular nuclei(Fig 1J, MHb, LHb) within the epithalamus. More strongly stained neurons had been located inside the mediodorsal, lateral dorsal, and ventral lateral thalamic nuclei (Fig 1J, MD, LD, VL) as well as the reuniens thalamic nucleus(Fig 1J, Re). Scattered lightly to moderately stained neurons were identified in the region with the globus pallidus(Fig 1J, GP). The cells of the lateral hypothalamic nucleus(Fig 1J, LH; Fig 2K) exhibited moderate to strong staining and have been a lot more densely arrayed. three.three Prosencephalon Starting in the forebrain level the distribution of TCF7L2-labeled cells integrated the robustly stained neurons from the subfornical organ(Fig 1K, SFO; Fig 2L), those of your lateral preoptic area(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; offered 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 numerous layers lining the ventricular and subventricular zones of your lateral ganglionic eminence(Fig 1L, LG) which form the septal(Fig 1L, Sn, Fig PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21237502 3C) and C-DIM12 web striatal neuroepithelium. Although present inside the identical 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 much less intense labeling for TCF7L2. The strongest expression of TCF7L2 within the neuroepithelium was located between E14 and E18.5. Some moderately stained and scattered cells had been found inside the medial septal nucleus(Fig 1L, MS). 3.4 Parasagittal Planes Parasagittal sections supplied further insight towards the distribution and expression of TCF7L2. The robust staining in 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 also because the unstained fibers in the fasciculus retroflexus(fr) above along with the cells on the zona incerta(ZI) under contributed for the well-defined demarcation of thalamic boundaries from the pretectum above along with the hypothalamus below. This sagittal section also illustrates labeled TCF7L2 cells of the tectum like moderately labeled cells of the pretectum(Fig 3D-E, Ptec), periaqueductal gray(Fig 3D, PAG), dorsomedial periaqueductal gray(Fig 3D, DMPAG) and superior colliculus(Fig 3D, SC) also as cells with the epithalamus including posterior commissural(computer), precommissural(PrC) and the medial and lateral habenular nuclei(Fig 3E, MHb, LHb) as well as the ventrolateral periaqueductal gray region(Fig 3D, VLPAG). In Fig 3F, moving subthalamically a clear profile of robust TCF7L2 labeled cells can be seen composing the ventromedial hypothalamic nucleus(VMH) close to the pituitary(P) in this parasagittal section near the midline. Within the brain stem adjacent to the thalamus the reticular cells with the pons have been located to exhibit a sturdy immunoreactive label for TCF7L2(Fig 3F, RFp). This was found to be characteristic on the reticular cells all through the brain stem such as these reticular cells on the medulla(Fig 3F, RFm) plus the gigantocellular r.
