However, this reviewer has a few concerns that need to be addressed before accepting this article for publication.
Given that dormant disseminated tumor cells (DTCs) highly express NR2F1 (Fluegel et al. Nat Cell Biol 2017), it is puzzling how NR2F1 in CAFs of the primary tumor would contribute to dormancy of DTCs. It would be nice, if the authors would discuss this important point in more detail.
