ANLN expression in breast cancer. Examples of immunohistochemical staining patterns of ANLN in breast cancer tissue shows nuclear expression in a variable fraction of tumor cells. Examples correspond to the different scores for nuclear fraction (NF) used in the analysis. 0–1% (a), 2–10% (b), 11–25% (c), 26–50% (d), 51–75% (e) and 76–100% (f). Scale bars 100 μm
