From: Expression of tryptophan 2,3-dioxygenase in mature granule cells of the adult mouse dentate gyrus
TDO immunoreactivity in immature and mature granule cells. A: Immature granule cells that were calretinin+ contained TDO. Arrows indicate examples of double labeling of calretinin with TDO. Arrowheads indicate cells labeling for calretinin only. B: Co-labeling of a mature granule cell marker, calbindin, with TDO. Note that almost all calbindin+ granule cells expressed TDO. Higher magnifications of the boxed-in areas in the merged images are displayed in the right-hand row. g, granule cell layer; h, hilus; m, molecular layer.
