Tube Networks in Bloom  The mouse retina is another system that has been extensively used to study the growth of blood vessels (angiogenesis). Shortly after birth, this vascular bed expands rapidly and is almost two-dimensional, showing in the same plane all of the hallmarks of vascular morphogenesis-sprouting, branching, fusion, remodeling, differentiation, and maturation-that make up the network of tubes that compose the circulatory system.

Axones nerviosos - A cross section of a bundle of nerve fibers.  Axons (orange) are wrapped in myelin (purple); an extension of the membrane of glial cells.  Myelin has high lipid content, and acts to insulate the axons, causing them to transmit nerve impulses much faster.

A reaction-diffusion system involving two chemicals spreading through a tray of gelatin that is slightly deeper at one end. Changes in distance from the chemicals' source and the gel's depth produce marked changes in pattern.

Colored scanning electron micrograph (SEM) of squamous cell carcinoma (cancer) cells from a human mouth. The many blebs (lumps) and microvilli (small projections) on the cells' surfaces are typical of cancer cells.
