Studies showed that theunderlying presence of a smallsubpopulation of undifferentiated cells,termed breast cancer stem cells(BCSCs), are most likely give rise totumor progression, spreading andresistance to conventional therapy.In the current study, keywords includingBreast Cancer Stem Cell, Biomarker, andCD۴۴ were reviewed from the list ofMesh and other credible websitesincluding PubMed, Science Direct andGoogle Scholar and the data wasorganized.
