From: Dexamethasone and Salbutamol Stimulate Human Lung Fibroblast Proliferation
The influence of dexamethasone and salbutamol on fetal lung fibroblast proliferation. Fibroblasts were incubated for 48 hours with medium alone or with either dexamethasone (10-4-10-8 M) (A) or salbutamol (10-6-10-10 M) (B) or dexamethasone and salbutamol (10-5-10-8 M) (C). TGF-β (10 ng/mL) was used as a positive control. Proliferation was assessed by [3H]-Thymidine incorporation, as detailed in Materials and Methods. Data are the mean ± standard error of the mean of 4 experiments performed in quadruplicates. In medium alone, counts per minute of [3H]-Thymidine incorporation were 474 ± 5. *P < 0.05; **P < 0.01; ***P < 0.0001.
