Plasticity of photoreceptor-generating retinal progenitors revealed by prolonged retinoic acid exposure

Table 2 Densities of rods and red cones in retinas probed for both rod and red cone opsins

	Cell densities (cells/3600 μm²) 60 hpf		Theoretical red to rod photoreceptor change (n = 6)^a
Cell Type	Control	RA	25%	50%
Rods	13.3 ± 4.0	16.9 ± 4.3	25.2 ± 4.9	37.2 ± 5.4
Cones:
Red	47.7 ± 8.2	35.8 ± 6.3	35.8 ± 5.9	23.8 ± 4.6

^aTheoretical patterns based on changing 25% or 50% of red cones in the native control patterns to rod identity.
