Cell extract is the fluid-like material made from cells after they are broken apart, while cytosol is the intracellular fluid of the cell containing various proteins, enzymes, ions, and other molecules. Cell homogenate is a sample made by homogenizing cells in a buffer solution, and cell content refers to the proteins, nucleic acids, and other cellular components released after cell lysis. These synonyms are commonly used in scientific research to characterize or analyze the content of cells or cellular materials.
