A list of normal and cancerous breast tissues indicating the GRB7 expression levels and frequencies. Under each GRB7 staining intensity (3+, 2+, 1+, 0) are the number of cases that show cytoplasmic staining only (c) or cytoplasmic plus membrane accentuation (c/m). (*) denotes GRB7 expression in the myoepithelial cells.
