From: Decreased expression of stomatin predicts poor prognosis in HER2-positive breast cancer
Immunohistochemical staining of breast cancer tissues. I–IV Expression of stomatin in breast cancer tissue showing the intensity score. I) Intensity score 0, no brown particles in the tumor cytoplasm or cell plasma membrane. II) Intensity score 1, faint brown staining of cell membrane. III) Intensity score 2, weak but definite brown staining of cell membrane. IV) Intensity score 3, deep brown staining of cell membrane with staining of cytoplasm
