Markers for eye primordia at the final embryonic stages. (A) Confocal microscopy image of nuclear SYTOX® staining of a stage 14 embryo in frontal view. The primordia of the lateral eyes are visible as shallow pits in the head region (arrowheads). (B) Expression of Pt-peropsin at stage 14 marks not only the lateral eye primordia (white arrowheads) but also the median eye primordia (black arrowheads).
