- Describe and give an example of the following types of stem cells: - totipotent - pluripotentCancer is a complicated series of diseases characterized by over-proliferation of cells within a tissue. While in some instances the primary tumor is the ultimate cause of death, in many cases the primary tumor metastasizes, or moves, through the lymph system to invade other tissues. The migration of tumor cells requires changes in the adhesion properties of the cell that allow it to move and invade more readily. There are several molecules involved in cell-to-cell connections and cellular architecture: laminins, matrix metalloproteinases, cadherins, and integrins. While mutations in genes that control the cell cycle or recognize DNA damage are the causes of tumor cell formation, tumor cell spread to other tissues may be caused by mutations in the genes the code for these extracellular proteins. The loss of cellular connections, cellular identification and signaling, and tissue structure may lead to the release of expanding tumor cells into the circulatory and lymphatic systems.
