Fibroblasts (IMAGE)
Caption
Fibroblast cells are integral to the body's immune response and for healing wounds. A new Princeton University study reveals that when fibroblasts go to sleep, entering a phase researchers term "quiescence," they are more active than previously thought. Here they are shown, via an image produced by an inverted fluorescence microscope, streaming toward a wounded skin cell.
