But scientists, starting with Alexander Kowalevsky had reported the presence of single (nonmotile) cilia in a variety of vertebrate cells (Kowalevsky 1867). These solitary and apparently ...

In her lab at Washington University in St. Louis, endocrinologist Jing Hughes studies a peculiar structure that sticks out of the surfaces of human pancreatic islet cells: the primary cilium. The ...

Proteins in the sheath of cellular protrusions control how effectively cells can adhere to surfaces. Biological cells often ...

but this requires that all cilia in a tissue orient the same way. Earlier studies indicated that both planar cell polarity (PCP) signalling and cilia-generated fluid flows could influence ciliary ...

The video also shows developing melanocytes (orange) scattered throughout the embryo. Melanocytes are cells that will give the zebrafish the colored pattern on its skin as an adult. In a zebrafish, ...
