Fig. 1. Effects of Dendropanax morbifera Leveille extract (DME) on SK-Hep1 cell growth. (A) Cell survival curve after DME treatment. Cells were cultured for 24, 48, and 72 hours with 0, 6.25, 12.5, 25, 50, and 100 µg/mL DME. The cell survival rate was determined by the MTT assay. (B) Morphological changes of DME-treated SK-Hep1 cells. DME suppressed SK-Hep1 cell growth, resulting in decreased cell density. The results are presented as the mean ± SD. Statistical differences were determined using Student’s t-tests (*P < 0.05, **P < 0.01, ***P < 0.001 vs. control). Cell morphology was visualized by inverted microscopy (×200). Scale bar = 50 µm.
