exposure of l5178y cells in culture to 0.2 mm hydroxyurea ( hu ) for up to 48 h induces inhibition of dna synthesis , killing of about 20 % of cells during the first 24 h exposure , gradual progress of cells into the state of unbalanced growth ( measured as progressive increase in cell size , dna protein ratio and acid phosphatase activity ) with final death of the majority of cells .
