Figure 1. Dopamine receptor deletion does
not alter photoreceptor cell survival in rd1 retinas in vivo.
Retinas from wild-type (A), rd1/rd1 (B), D1−/−,
rd1/rd1 (C), D2−/−, rd1/rd1 (D), D4−/−,
rd1/rd1 (E), and D5−/−, rd1/rd1 (F)
were harvested at postnatal day 21. The ONL of rd1/rd1
retinas was reduced to a monolayer of photoreceptors, regardless of DR
genotype. Abbreviations: outer segments (OS); inner segments (IS);
outer nuclear layer (ONL); outer plexiform layer (OPL); inner nuclear
layer (INL); inner plexiform layer (IPL); ganglion cell layer (GCL).
The scale bar represents 10 μm.
