Structural Group depletion causing distorted cortical unit shape as well as abnormal SRs. a, c, and e Control, Paralog Group 2- and Structural Group 2-depleted cells, respectively. The yellow box in each image is enlarged (b, d, and e) to show cortical unit rows (green) with SRs (red). b, d Organized cortical units as well as SR rows that extend between the posterior pole and the anterior pole in the Control and Paralog Group 2-depleted cells, respectively. f The severely distorted cortical units and abnormal SR rows in a Structural Group 2-depleted cell. Arrow in f points to SRs that are directed across the row and are abnormally curved in shape. All images are of the dorsal surface, but distortion of cortical units with abnormal SRs in Structural Group-depleted cells can occur anywhere on cells’ surfaces except the oral groove. Antibodies used are anti-Cortical unit ridge antibody (green) and anti-SR (red). Scale bars are 10 μm (a, c, and e) and 3 μm (b, d, and f)
