Cytolysis, also known as osmotic lysis, occurs when a cell bursts and releases its contents into the extracellular environment due to a great influx of water into the cell, far exceeding the capacity of the cell membrane to contain the extra volume. This is a concern particularly for cells that do not have a tough … See more Cytolysis can be caused by many factors, from the tonicity of the extracellular fluid to the activity of other cells affecting the structure of the cell membrane. See more Cytolysis is often used as a tool of survival by various cells.
