Effects of different treatments on the proliferation of WPMY-1 cells. A Images of WPMY-1 cells treated without TGF-β (control), with TGF-β (5 ng/mL), or with TGF-β supplemented with lycorine or 6α-hydroxybuphanidrine (each 5 ng/mL). All images were captured at 100 × magnification; scale bar = 20 µm. B Bar graph revealing the percent cell proliferation represented as the means ± SD (**P < 0.01 and ***P < 0.001)
