Expression patterns of KRT5 in the luminal subtypes. (A) Representative images of the different types of KRT5 expression patterns. (B) Proportions of the expression patterns within each molecular subtype. Labels: 1 Layer, one continuous layer of positive cells; NC, noncontinuous layer of positive cells; ML, multilayers of positive cells; All, all cells positive; Diffuse, scattered positive cells; Negative.
