Fibroblasts are the most common cell in our bodies, but few people have actually heard of them. They are responsible for making collagen and contributing it to the loose connective tissue of the extracellular matrix. When tissue injury occurs they stop making collagen, change to a more streamlined shape and migrate to the area of injury, mounting part of the inflammatory response. Once this resolves they migrate back to where they came from, change back to their original shape and resume making collagen.
