- Study in Blood uncovers unique pattern of DNMT3A mutations in frequent blood donors responding specifically to erythropoietin.
- This reveals a previously unknown mechanism of clonal selection in hematopoietic stem cells.
- The mutations exhibited different environmental response patterns compared with the well-known preleukemic R882 mutations.
- The research suggests significant implications for understanding the dynamics of clonal selection in HSCs and its connection to frequent blood donation.
- The study authors stated that erythropoietin was identified as a novel environmental factor that favors HSC carrying certain DNMT3A mutations.
