The descriptor can apply to objects of different types, including cells, where one mechanism of crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis. ... As a result, the cell shrinks and the cell membrane develops abnormal notchings.

When a red blood cell is placed in a hypertonic solution, such as a highly saline environment, there is a lower concentration of solute particles inside the cell than outside in the extracellular space. ... As water leaves the cell, it shrinks and develops the notched appearance characteristic of crenation.
