Fig. 6: equinox is required for blastema formation.
From: The planarian wound epidermis gene equinox is required for blastema formation in regeneration
a, b Short-term bmp4 RNAi is sufficient to block blastema formation (a) but does not block neoblast accumulation or PCG rescaling (b). Blue arrows, anterior edge of posterior PCG expression. a, b n = 2 independent experiments. c The equinox RNAi regeneration defect is not suppressed by β-catenin-1 RNAi. equinox; β-catenin-1 double RNAi animals were able to rescale positional information and form new photoreceptor neurons (opsin) without growing blastemas. n = 3 independent experiments. Scale bars, 100 μm.
