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.

✯ HeLa cells are a continuously cultured cell line of human cancer cells, which are immortal & thrive in the laboratory. They are widely used in biological and medical research. The spherical cell at centre is undergoing apoptosis (programmed cell death). Apoptosis occurs when a cell becomes old or damaged. Blebs (vesicles) called apoptotic bodies form on its surface, which prevent toxic or immunogenic substances from leaking when it is phagocytosed (engulfed and digested) by specialist…

Stomach cells naturally revert to stem cells to repair damage from acid and digestive fluids

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

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).

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.

Confocal light micrograph of a purkinje cell (stained with green fluorescent protein), a type of neuron (nerve cell). Purkinje cells consist of a flask-shaped cell body with many branching processes (dendrites) that receive impulses from other cells. Purkinje cells form the junction between the granular and molecular layers of the grey matter of the cerebellum.

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.
