Figure 2From: The in vitro influences of epidermal growth factor and heregulin-β1 on the efficacy of trastuzumab used in Her-2 positive breast adenocarcinomaFlow cytometry histograms analysed with deconvolution software. Gaussian curves were utilised to divide histograms into G1 phase (left), S phase (centre) and G2 phase (right) A) Untreated MCF-7 cells in DMEM with 10% FCS; B) Trastuzumab treated MCF-7 cells after 72 hours illustrating G1 accumulation; C) Untreated SK-Br-3 cells in RPMI with 10% FCS; D) Trastuzumab treated SK-Br-3 cells after 24 hours illustrating G1 accumulation.Back to article page
