Briefly, actively proliferating cells were incubated with colchicines (0.1 lg/ml) for 4 h at 37 _C. The cells were washed twice with DPBS, trypsinized, suspended in a chilled hypotonic solution (68 mM KCl) and incubated for 20 min at 37 _C and then fixed for 10min in chilledfixative (methanol and glacial acetic acid, 3:1). The pellets were suspended in 5 ml of chilled fixative for another 10min. The metaphase spreads were prepared by dropping the cell suspension onto ice cold glass slides. - T" ~0 O" Q; Z# m- ]; ~9 v4 O6 d
