Stages of rod photoreceptor ciliogenesis. At P0-P1, the centrosome consisting of mother and daughter centrioles (MC, DC) acquires a ciliary vesicle (CV) at its distal end. Soon, from P3-P4, the mother centriole docks to the cortex of the inner segment. At P5-P6, the axoneme (Ax) emanates from the MC and MC becomes a basal body (green). A- and B-tubules (black) extend at P7-P8, and the transition zone TZ is established. The cell membrane evaginates and discs are formed. The outer segment is considered mature at three weeks of age (P21). Adapted from May-Simera et al., 2018.
