Pericyte on Capillary

Share this animation:

Pericytes are contractile cells with a “spider-like” shape found on the outside of the small vasculature. Pericytes play important roles in regulating capillary blood flow and are also responsible for maintaining permeability of the blood-brain barrier.

We have received a tremendously enthusiastic response from students, both in freshman biology and sophomore cell biology courses.
