Clara cell proliferation on matrix substrates. Adherent cells at 18 hours were treated with BrdU in 10% FCS containing media for 24 hours. The percentage of cells incorporating BrdU over this time period on Fn, Col I, Lm 511, Col IV, Lm 332, Lm 111 or uncoated (Un, white) slides is shown. Results are expressed as mean percent of BrdU positive cells per high power field +/- SEM from three independent isolation experiments. No conditions were statistically significant from uncoated wells.
