    Clumps of Neurons Help Scientists Study Gut Disorders: Scientific American These neurospheres—free-floating balls of glia (red), neurons (green) and stem cells—were cultivated in a lab from stem cells taken from the intestine or stomach of a mouse. Researchers use the neurospheres to test treatments for gut motility disorders, in which portions of the intestine, sometimes referred to as the second brain, lack sufficient nerve cells to function properly.

    A particularly pernicious enemy - cancer stem cell.

    The retina contains five classes of neurons: photoreceptors (purple), horizontal cells (yellow), bipolar neurons (green), amacrine cells (pink and blue), and ganglion cells (pink and blue). In this cross section of an adult mouse retina, only a subset of bipolar cells, “the ON bipolar cells” are visible by their expression of GFP (green). The pink and blue speckled striations at the bottom of the image mark the fiber layer, which contains the ganglion cell axons that will form the optic nerve.

    Stomach cells naturally revert to stem cells to repair damage from acid and digestive fluids...isn't that just amazing!!

    Developing nerve cells

    Nerve cells. Coloured scanning electron micrograph (SEM) of nerve cells, known as neurones. Nerve cells occur in the brain, spinal cord, and in ganglia. Each nerve cell has a large cell body (brown) with several long processes extending from it. The processes usually consist of one thicker axon and several thinner branched dendrites. The dendrites collect information in the form of nerve impulses from other nerve cells and pass it to the cell body.

    Coloured light micrograph of a 1-week old, nerve cell (neuron) cluster. This cell cluster has been grown in culture. The nerve cell bodies are still grouped together (centre) and the neurites (either axons or dendrites) that will connect the cell bodies to form a network, are beginning to develop (dark lines).

    Human embryonic stem cells

    Not a really a Stem Cell, but is a nice art piece

    This image represents human neural stem cells from fetal cortex. Cells are stained for nuclear (Hoechst, blue), neuronal (TUJ-1, green), and astrocyte (GFAP, red) markers.Corey Seehus, Brain Cells Inc, USA

    Hematopoiesis from Pluripotent Stem Cell

    Light micrograph of synapses between a motor neurone (tree-like) & skeletal muscle cells (bands in background). The end of the axon (large fibre) of a motor neurone in contact with a muscle cell divides into branches, each one terminating in a motor end plate on a different muscle fibre.
