Fluorescent light micrograph of a group of neural stem cells in culture.
- The stem cells are differentiating into neurons (red) and nerve support cells (green), which are then migrating out of the neurosphere.
- Cell nuclei are dyed blue.
- Intermediate filaments are green.
- Beta-tubulin III, one of the proteins that make up microtubules, is red.
Intermediate filaments and microtubules are part of the cell’s cytoskeleton, responsible for intracellular transport, cell structure and motility.
