PTPH1-KO thalamus . a: LacZ expression detected in several thalamic nuclei (4×; scale bar: 165 μm): mediodorsal (MD), central lateral (CL), anteroventral (AV), anteromedial (AM), ventromedial (VM) ventral posteromedial (VPM) and ventrolateral (VL) thalamic nuclear groups. MHb: medial habendular nuclei. b: LacZ expression detected in the ventral posteromedial thalamic nuclei (VPM) and it is present also in ventrolateral (VL), ventromedial (VM), ventral posterolateral (VPL), laterodorsal (LD), posterior (Po) and reticular (Rt) thalamic nuclei (2.5×, scale bar: 130 μm). c: LacZ is expressed in the dorsal lateral geniculate nucleus (DLG) and in the lateroposteral thalamic nuclear group. In this caudal section LacZ staining is more intense in the posterior nucleus, but present also in VPM, VPL and VPPC (ventral posteromedial parvicel) thalamic nuclei (2.5×, scale bar: 13 μm). d: Detail of beta-gal expression in neural cell body of VPL and VPM at 40× (scale bar: 20 μm) and e: at 63× (scale bar: 10 μm).
