Nerve and glial cells, fluorescence light micrograph. These are neural stem cells that have differentiated into neurons (nerve cells, green) and glial cells (support cells, red). The branching processes from the neurons are called dendrites. Fluorescent markers have been used to highlight proteins (red and green) and cell nuclei (blue). The proteins stained here are beta III-tubulin (green), a cytoskeleton element found in neurons, and GFAP (glial fibrillary acidic protein, red), forming the cytoskeleton of the glial cells. Cell nuclei have been stained with DAPI. This sample is from rat tissue.
