This photomicrograph revealed the effects produced upon a number of peripheral human lymphocytes, when they were stimulated by the addition of the chemical, phytohemagglutinin (PHA). Note the increased heterogeneity within the nuclear chromatin. Also note, the mitotic activity displayed by two of the lymphocytes at the bottom. See PHIL 21377, for another view demonstrating the effects of PHA, on another group of these lymphocytes.
