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.

Neural rainbow Individual neurons in the mouse brain show up differently colored in this Brainbow-labeled sample of a cerebral cortex. Brainbow is the process of labeling neurons with fluorescent protein to distinguish them and follow their paths through brain tissue.

Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen

✯ 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…
