when day 3 lak cells were transferred to new medium ( cm to cm and aim v to aim v ) , a highly reproducible expansion of these cells was demonstrated which was significantly better for cells expanded in aim v medium versus cells expanded in cm ( mean fold expansion on day 21 of culture ; 201 versus 54 , aim v medium versus cm , respectively , p less than 0.005 , n = 4 consecutive experiments ) .
