The growth and recurrence of a number of cancers is driven by a scarce population of cancer stem cells (CSCs), which are resistant to most current therapies. It has been shown previously that natural killer (NK) cells recognize human glioma, melanoma, colon and prostate CSCs in vitro. We herein show that human and mouse breast CSCs are also susceptible to NK cytotoxic activity in vitro. Moreover, CSC induced autologous NK cell activation and expansion in vivo, which correlate with the inhibition of CSC metastatic spread. These data suggest that NK cells control CSC metastatic spread in vivo and that their use in breast cancer therapy may well be fruitful.

Abstract
The growth and recurrence of a number of cancers is driven by a scarce population of cancer stem cells (CSCs), which are resistant to most current therapies. It has been shown previously that natural killer (NK) cells recognize human glioma, melanoma, colon and prostate CSCs in vitro. We herein show that human and mouse breast CSCs are also susceptible to NK cytotoxic activity in vitro. Moreover, CSC induced autologous NK cell activation and expansion in vivo, which correlate with the inhibition of CSC metastatic spread. These data suggest that NK cells control CSC metastatic spread in vivo and that their use in breast cancer therapy may well be fruitful.File | Dimensione | Formato | |
