Abstract:
Human cancer stem cells represent promising tools for new approaches to pathway-targeted drug discovery and preclinical screening. Because of their distinctive capability to recapitulate the development of the original tumors in vivo, the study of human cancer stem cells (CSCs) largely relies on models of xenograft transplantation into immunodeficient mice. In this frame, immunity and microenvironment-related issues need careful consideration. Here we shortly revise present knowledge on xenograft-related aspects of human CSCs studies.
Insights
Human cancer stem cells (CSCs) are valuable for drug discovery. Xenograft models in mice are crucial for studying CSCs, but require careful consideration of immunity and microenvironment factors.
