Osteoblast cells. Fluorescence light micrograph of osteoblast cells stained for cytoskeletal proteins (purple and green) and cell nuclei (yellow). The cytoskeleton of a cell consists of protein filaments and microtubules that control cell shape and contribute to cell movement. Osteoblasts are cells that produce new bone tissue. This image shows the osteoblasts cells fluorescently labeled with Alexafluor 488 that stains alpha tubulin (green) and phalloidin marking the actin (purple) and DAPI highlighting the nucleus (yellow).
