Fig. 8: Acute cytotoxicity examination (fluorescence intensity and inhibition rate) of cynaropicrin in CCRF-CEM xenograft tumor zebrafish model (n = 5 zebrafish).

The red fluorescence highlights CCRF-CEM tumor mass. Images were taken at 60× magnification (scale bars = 100 µm). *P < 0.05, **P < 0.01, ***P < 0.001 if compared to the model.
