(A)–(B) ovo RNAi eliminates regenerative eye progenitors as assessed by markers for PRN (otxA+/eya+), PC (sp6-9+/eya+), and general eye progenitors (six-1/2+/eya+). Arrows indicate double-positive cells.
(C)–(D) Most regenerative ovo+ progenitor cells are eliminated by six-1/2 and eya RNAi.
(E)–(F) sp6-9 RNAi eliminates most ovo+ pigment cell progenitors (ovo+/otxA), and otxA RNAi eliminates most ovo+ photoreceptor neuron progenitors (ovo+/sp6-9).
n = 8 eyes + trails for all quantifications.
Error bars represent SD. *** p < .005. Scale bars, 50 µm (A,C,E), and 20 µm (A, insets).
