Saw Palmetto Extract Inhibits Metastasis and Antiangiogenesis through STAT3 Signal Pathway in Glioma Cell

Figure 1

The apoptosis of glioma cell induced by saw palmetto through TUNEL assay. (a) is the control group, (b) is the low dose group in which the rats received administration of 50 mg/kg saw palmetto extract every day for 4 weeks, and (c) is the high dose group in which the rats received administration of 300 mg/kg saw palmetto extract every day for 4 weeks. (d) is the histogram to evaluate the apoptosis cell induced by saw palmetto of above three groups. means .
