Core Tip

Core tip: Cancer progression relies on a small population of cancer stem cells (CSC), characterized by longevity, self renewal, drug resistance and requirement of a niche. In addition, CSC abundantly deliver exosomes (TEX) allowing CSC a long distance communication. At the descriptive level, CSC are characterized by a set of so called CSC markers. We here discuss for pancreatic cancer that the CSC markers CD44v6, c-Met, Tspan8, alpha6beta4, EpCAM, claudin7, CXCR4 and prominin1 can in a concerted activity account for all CSC features. This includes CSC TEX activity due to the engagement of CSC markers in TEX biogenesis and enrichment in TEX.
