Are all cell nuclei in the body the same?

Posted July 12, 2023


Answer

Some cells in the body have a different type of nucleus, and some do not have a nucleus. There are unusual types of shapes of the nucleus for different types of cells. For example, the shape of the nucleus of white blood cells is irregular and dependent on the WBC type. Monocytes have a kidney shaped nucleus, eosinophils have a bi-lobed nucleus, and neutrophils are multinucleated. The nuclei of most cells, however, are either spherical or oval shaped. Some cells don't contain DNA packaged in a cell nucleus. For example, mature red blood cells and cornified cells in nails, hair, and skin do not have a nucleus. Mature hair cells also do not contain any nuclear DNA.
