Figure 1. tdTomato-expressing bipolar cells in the 5-HTR2a-cre transgenic mouse line. A: tdTomato-expressing cells viewed in a retinal whole mount with the focal plane at the distal portion of the INL. B: tdTomato-expressing cells viewed in a retinal vertical section. The arrow points to the bipolar cells with their axon terminals located in the proximal portion of the IPL. ONL, outer nuclear layer; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer. The scale bar represents 50 µm in A (applies to B).
