A. Sakai et al., THE EFFECTS OF FULLERENES ON THE INITIATION AND PROMOTION STAGES OF BALB 3T3 CELL-TRANSFORMATION/, Fullerene science and technology, 3(4), 1995, pp. 377-388
Fullerene C-60 and a mixture of fullerenes C-60 and C-70 were solubili
zed in a culture medium with poly(vinylpyrrolidone) and examined for t
he effects on two-stage cell transformation in vitro, a model of carci
nogenesis. They showed neither initiating nor promoting activity in th
e assays.
