From: Convergent evolution of the sensory pits in and within flatworms
Formation of the pits during asexual development, as visualized with antibodies against tyrosinated tubulin (yellow, A–D), phalloidin staining for F-actin (green, A′–D′), and Hoechst staining for cell nuclei (cyan). Schematic drawings of the pit formation (A″–D″), scale bars 10 μm.
