Variable patterns of transgene expression in Tbx2.6gV transgenic mice. (A1, A2) Line #008: a zonal subset of olfactory sensory neurons (OSNs) projecting axons to the ventrolateral region of the olfactory bulb (OB). (B1-B3) Founder #1: the granule cells (Gr) in the main OB. (C1-C6) Line #001: the neurons in the anterior olfactory nucleus (AON) projecting axons to the contralateral AON and OB via the anterior commissure (ac) (C2-C5) and the neurons in the central nucleus of amygdala (Ce) (C6). (D1-D4) Line #004: the granule cells in the accessory OB (AOB) (D2) and the neurons in the nucleus of lateral olfactory tract (NLOT) (D3, D4). (E1-E5) Founder #3: a small population of neurons in the lateral entorhinal cortex (LEnt) projecting axons to the dentate gyrus of the hippocampus (E2-E5) and a ventrolateral zonal subset of OSNs. PMCo, posteromedial cortical amygdaloid nucleus. (F1-F4) Line #103: the neurons in the ventromedial hypothalamic nucleus (VMH) (F2-F4) and a ventrolateral zonal subset of OSNs. (G-N) Other representative examples of Tbx2.6gV transgenic lines with various patterns of gapVenus expression. MM, medial mammillary nucleus.
