abstract：:Cancer stem cells (CSCs) are a sub-population of cancer cells that possess characteristics associated with normal stem cells but with the peculiarity that they are tumourigenic. This property allows them to persist in the tumour population, causing relapse and metastasis by giving rise to new tumours. Accordingly, if ...
