Basal bodies in Xenopus.

Xenopus has been one of the earliest and most important vertebrate model organisms for investigating the role and structure of basal bodies. Early transmission electron microscopy studies in Xenopus revealed the fine structures of Xenopus basal bodies and their accessory structures. Subsequent investigations using multiciliated cells in the Xenopus epidermis have further revealed many important features regarding the transcriptional regulation of basal body amplification as well as the regulation of basal body/cilia polarity. Future basal body research using Xenopus is expected to focus on the application of modern genome editing techniques (CRISPR/TALEN) to characterize the components of basal body proteins and their molecular functions.
