the evidence presented is consistent with premises that : ( a ) plaque-forming cells in mitosis do not release sufficient antibody to be detected , ( b ) mitotic blocking agents , by arresting plaque-forming cells in metaphase , prevent not only detection of these cells but also the increase in number of plaque-forming cells which would have resulted from cell division , ( c ) mitotic blocking agents do not affect release of antibody by cells in interphase .
