Figure 3. Effects of epiregulin on the proliferation of HCECs

Serial concentrations of recombinant epiregulin were added to the medium, and after 6 days the cell numbers were counted using a hemocytometer. The bottom panel shows representative photographs of HCECs 6 days after the addition of epiregulin. (B: 0 ng/ml, C: 1 ng/ml, D: 10 ng/ml) The scale bar is equal to 400 μm.
