cilia

Scientists at UC San Francisco have discovered that cells can also use the cell cycle to control how they sprout hair-like projections called cilia.

Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids.

The researchers found many of the genes involved in the two diseases implicated primary cilia, tiny antenna-like structures on the cell's surface that sense chemical changes in the cell's surrounding environment.

They found that the infants who experienced respiratory distress had malfunctioning cilia in their airways, which refers to the hair-like structures that cleanse the airways of inhaled particles and pathogens.

Primary cilia are possibly also involved in receiving and sending signals to the rest of the body which can also enhance wound repair.
