Metastasis in Motion: Part 2
Figure 2. This movie clip is an animation of the later steps in the metastatic cascade. It depicts a normal cell floating through a blood vessel with other normal cells and attaching through specific receptors to the endothelial cells lining the blood vessel. The tumor cell then extravasates from the blood vessel, migrates to a nearby site and attaches to the extracellular matrix, where it begins to divide and form the basis of a metastatic colony of cells.
