Treatment with VIP in combination with forskolin or IBMX promotes SLHMG proliferation. Cells were treated with VIP (10−8 M), forskolin (10−6 M), or IBMX (10−3 M), alone or in combination, for 7 days. Data are shown for two separate experiments (A) and (B) and each column represents the mean of three wells ± SEM. *P < 0.05, two-tail, compared with untreated cells. †P < 0.05, one-tail, compared with untreated cells.
