Primary cilia are sensory organelles present on the cell surface; however, their physical structure has not been defined due to technical reasons. A new PNAS study examined primary cilia in human ...

Many cells in our body have a single primary cilium, a micrometer-long, hair-like organelle protruding from the cell surface that transmits cellular signals. Cilia are important for regulating ...

Multiciliated ependymal (E1) cells line the brain ventricles and are essential for brain homeostasis. We previously identified in the lateral ventricles a rare ependymal subpopulation (E2) with only ...
