Photomicrographs of neoplastic +SA mammary epithelial cells in culture treated with a subeffective dose of γ-tocotrienol (γT 3 ) alone or in combination with a subeffective dose of erlotinib (E), gefitinib (G), or trastuzumab (T). Cells were plated at a density of 5 × 104 cells (Day 0) per well (6 replicates/group) in 24-well plates and exposed to respective control and treatment serum-free defined media for a 4-day period. Magnification is 100×.
