Temporal expression of zebrafish SoxC genes during retinal regeneration. A PCR results of the expression of zebrafish SoxC genes (sox4a, sox4b, sox11a, sox11b, and sox12) in the whole retina at the indicated time points. The pro-neural gene ascl1a served as a positive control for retinal regeneration, and gapdh as a loading control. B qPCR analysis of the expression of zebrafish SoxC genes after retinal injury at indicated time points (n = 3 biological replicates).
