this postulate was developed , in part , because ( 1 ) mouse tail epidermis contains fewer atpase-positive ( presumably langerhans ) cells than does abdominal epidermis , and ( 2 ) when tails of c57bl/6 mice were painted with dinitrofluorobenzene ( dnfb ) , the mice were less sensitive than those painted on the abdomen .
