Renal cell carcinoma (RCC) is a major neoplasm with high incidence in western
countries. Tumors are heterogeneous and are composed of differentiated cancer
cells, stromal cells, and cancer stem cells (CSCs). CSCs possess two main
properties: self-renewal and proliferation. Additionally, they can generate new
tumors once transplanted into immunodeficient mice. Several approaches have been
described to identify them, through the expression of cell markers, functional
assays, or a combination of both. As CSCs are involved in the resistance
mechanisms to radio- and chemotherapies, several new strategies have been
proposed to directly target CSCs in RCC. One approach drives CSCs to
differentiate into cancer cells sensitive to conventional treatments, while the
other proposes to eradicate them selectively. A series of innovative therapies
aiming at eliminating CSCs have been designed to treat other types of cancer and
have not been experimented with on RCC yet, but they reveal themselves to be
promising. In conclusion, CSCs are an important player in carcinogenesis and
represent a valid target for therapy in RCC patients.
