The inverse association between crocidolite uptake and cell density. MeT5A cells at confluences of 20, 30, 50, 70 and 90% were incubated with 5 µg/cm2 crocidolite for 2 h on two separate occasions (Test 2-1 and Test 2-2). The cytograms (A) and the histogram (B) of Test 2-1 indicated a decrease in SSC with the increased cell density (% confluence). (C) In both of these tests, the mean SSC ratio was inversely correlated with the confluence of cells (p<0.01).
