The orientation of ciliary basal bodies in quail oviduct is related to the ciliary beating cycle commencement

Abstract

In mature ciliated cells, the basal feet associated to the basal bodies point out in the direction of the effective stroke of the ciliary beating. In contrast, during ciliogenesis, the basal feet of the newly anchored basal bodies are randomly oriented. The reorientation of basal bodies occurs during the beginning of the coordinated beating cycle of the cilia.
