Niclosamide inhibits serum‐induced (15% FBS) and PDGF‐BB‐induced A10 cell proliferation. (A) A10 cells were cultured in DMEM supplemented with 15% FBS in the absence or presence of niclosamide (Nic; 0.5–2 μM) for 24 h, with 0.2% FBS condition as control. n = 8 in each group. *P < 0.05, significantly different from 0.2% FBS (control), #
P < 0.05, significantly different from 15% FBS. (B) Quiescent A10 cells were incubated with PDGF‐BB (30 ng·mL−1) in the absence or presence of niclosamide (0.05–2 μM) for 24 h. n = 12 in each group. The control medium contains 0.2% FBS. *P < 0.05, significantly different from control, #
P < 0.05, significantly different from PDGF‐BB.
