02 Jul 2011 --- deposition, full frame, backgrounds is the substance or matter of a tissue which is not a cell. Typically it is composed of protein polymers enriched with sugary branches. Shown here are fibronectin fibers. It is also known for sequestering or storing and then liberating or activating growth factors and matrix proteases, thus directly affecting cell behavior. The confocal image indicates chronological matrix deposition represented by the different colors. X63 --- Image by © Dr. Edna Cukierman/Visuals Unlimited/Corbis
