Fig 4. Detection of apoptosis using the TUNEL assay.

Fig 4

Control tumor (A), low-dose FALHE treatment (B), high-dose FALHE treatment (C), and tamoxifen treatment (D). TUNEL assay were subjected on sections of all breast cancer groups. Microscopic observation of tumor sections of the tumor control and treated tumor green color particles showing the presence of apoptosis in the treated tissues. Low dose of FALHE shows low number of apoptotic cells but it is significantly increased in FALHE high dose and tamoxifen group. Magnification, 40×.
