Massive centriole production can occur in the absence of deuterosomes in multiciliated cells
Multiciliated cells (MCCs) amplify large numbers of centrioles, which convert into basal bodies that are required for producing multiple motile cilia. Most centrioles amplified by MCCs grow on the surface of organelles called deuterosomes, while a smaller number grow through the centriolar pathway i...

description | Multiciliated cells (MCCs) amplify large numbers of centrioles, which convert into basal bodies that are required for producing multiple motile cilia. Most centrioles amplified by MCCs grow on the surface of organelles called deuterosomes, while a smaller number grow through the centriolar pathway in association with the two parent centrioles. Here we show that MCCs lacking deuterosomes amplify the correct number of centrioles with normal step-wise kinetics. This is achieved through a massive production of centrioles on the surface and in the vicinity of parent centrioles. Therefore, deuterosomes may have evolved to relieve, rather than supplement, the centriolar pathway during multiciliogenesis. Remarkably, MCCs lacking parent centrioles and deuterosomes also amplify the appropriate number of centrioles inside a cloud of pericentriolar and fibrogranular material. These data show that centriole number is set independently of their nucleation platforms and that massive centriole production in MCCs is a robust process that can self-organize. |
