From: Cancer stem cell markers in breast cancer: pathological, clinical and prognostic significance
Photomicrographs of CSC marker expression in invasive breast carcinoma. A. Membranous CD44 (red) staining and cytoplasmic CD24 (brown) staining of carcinoma cells. Tumours contained different proportions of positive cells, including cases dominated by CD44+CD24-/low cells (left panel) and others composed of CD24 expressing cells exclusively (right panel). B. Examples of low (left panel) and high (right panel) ALDH1A1 expression. C. Examples of high ALDH1A3 (left panel) and high ITGA6 (right panel) expression.
