Zhao et al demonstrate that HSCs have a back-up system in stressed condition. Both reserve and active stem HSCs are maintained in the bone marrow by specific niches. While the latter are chemo-sensitive, the former survive and restore stem cells, and thereby generate the blood system. Image credit: Zhao et al, doi: 10.1016/j.celrep.2018.12.093.
