Dlx5/6i-cre lineage gives rise to TH⁺/calbindin⁺/calretinin⁺ OB interneurons. A, EGFP expression in OB from Dlx5/6i lineage at P0. B–D, Examples of EGFP⁺ cells that coexpress TH, calbindin, or calretinin. E, EGFP expression in OB from Dlx5/6i lineage in adult. E′, Higher magnification of OB showing that EGFP expression is found in all layers of the OB. F–H, Examples of EGFP⁺ cells in adult OB that coexpress TH, calbindin, or calretinin. Arrows point to double-labeled cells. GL, Glomerular layer; EPL, external plexiform layer; MCL, mitral cell layer; GCL, granule cell layer; OBc, olfactory bulb core. Scale bars: A, E′, 100 μm; B–D, F–H, 30 μm; E, 0.5 mm.
