Colorectal specificity of this CD44-fingerprint is detailed and proven elsewhere (publication in progress, Rásó-Barnett et al.), here we just demonstrate a few samples of CD44 fingerprints of other tumour types, i.e. MCF7 (breast cancer), HT199 (melanoma), A431 (vulvar epidermoid carcinoma), and K562 (myelogenous leukemia) respectively. This evidence concerns the gene CD44 and breast cancer.
