Studying the individual genes in the 12-gene and 72-gene signatures, revealed that the great majority were overexpressed in the EpCAM + /ITGA6 + /ALDH + population compared to all other luminal/LP populations, a result which was highly significant as assessed using 100,000 Monte-Carlo randomizations (Fig. 6b , P < 1e−5).
