Summary illustration of the roles of primary and motile cilia in ependymal planar polarity. Normal development of ependymal planar polarity is shown in the left column. Loss of motile cilia from ependymal cells (middle column) does not dramatically alter translational polarity of basal body patches but it disrupts their rotational polarity, while loss of both primary cilia from radial glial progenitors and motile cilia from ependymal cells (right column) dramatically disrupts translational polarity.
