in the first period ( nearly 3 days after pha stimulation ) tpa induces no significant differences in the characters under consideration , but in the later period , when the proliferation of the cultures stimulated by pha alone is reducing , in other cultures stimulated by pha plus tpa the percentage of cells in s-phase does not reduce , whereas the percentage of cells in g2-phase is rising , which may suggest that this phase is blocked .
