Small intestine villus,fluorescence deconvolution micrograph. Fluorescent dyes have been used to highlight cellular structures and proteins: microvilli actin (green),cell nuclei (blue). Villi are the functional structures lining the walls of the intestines. Actin is a protein that is a major part of a cell's cytoskeleton,here highlighted in the microvilli. These are small structures,covering the surface of a villus,which absorb nutrients from digested food. The cell nuclei seen here are part of the columnar epithelium that forms the shape of a villus | |
