Bmi1 induction protects hematopoietic stem cells against pronounced long-term hematopoietic stress
The Polycomb complex protein Bmi1 is regarded as a master regulator of hematopoietic stem cells (HSCs). In the blood system, HSCs express Bmi1 most abundantly and Bmi1 expression vanes as cells differentiate. Furthermore, Bmi1 has been found overexpressed in several hematologic cancers. Most studies exploring the normal role of Bmi1 in HSC biology have utilized loss-of-function models, which have
