There are several kinds of cell proliferation assays to determine cell proliferation, which could be used as a prognostic and diagnostic tool in certain cancers. Most of these assays are based on the quantification of DNA levels or synthesis, cellular metabolism or proliferation-specific proteins to assess the extent of cell proliferation. DNA synthesis is a very popular and widely used method to study cell proliferation.
