Fibroblast cells. Immunofluorescence light micrograph of fibroblast cells. The cell nuclei are purple, actin filaments are cyan and microtubules, protein filaments that make up part of the cytoskeleton, are yellow. Fibroblasts are cells that give rise to connective tissue such as collagen, the main structural protein in the body. They are important in wound healing. Magnification: x500 when printed at 10 centimetres wide.
