In the present study, 144 samples of invasive breast carcinoma, no special type were distributed in 15 tissue microarrays (TMA) and then evaluated for expression of the CD44+/CD24- phenotype and ALDH1 to understand the importance of these CSC markers and the clinical aspects of breast cancer.
CD44(+)/CD24(-/low) cancer stem/progenitor cells are more abundant in triple-negative invasive breast carcinoma phenotype and are associated with poor outcome.
