Cancer stem cell markers and significance

Cancer stem cell marker	Expression	Significance
CD44	Hyaluronate receptor	Cell growth, differentiation, motility, increased chemoresistance, self-propagation
CD133	Transmembrane glycoprotein	Increased tumor formation, increased chemoresistance, regeneration of original tumor cells
CD117	Tyrosine kinase receptor	Cell signaling, apoptosis, cell differentiation, proliferation, cell adhesion
ALDH1A1	Cell protector from aldehydes	Regeneration of tumor cells, chemoresistance
EpCAM (CD326)	Transmembrane glycoprotein	Cell adhesion, cell proliferation, tumor formation, epithelial to mesenchymal transition
CD24	Transmembrane glycoprotein	Cell adhesion, aggressive phenotype, metastasis
