Researchers from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and ETH Zurich have created the first integrated map detailing the metabolic and molecular changes in human blood stem cells as they age, specialize, or turn cancerous. Their innovative research, made possible by highly sensitive low-input techniques, identifies the nutrient choline as a key player in preserving youthful stem cell traits. This work offers profound insights into stem cell health and disease, suggesting promising directions for nutritional and therapeutic interventions to maintain a healthy blood system. The findings are published in the journal Nature Cell Biology.
The study also revealed changes in the lipid composition of blood stem cells which alter the membrane structure of the cells and affect how they sense and respond to their surroundings. “These findings provide new directions for exploring how metabolism not only shapes a cell’s internal machinery but also its interactions with the environment,” says co-corresponding author Jörg Büscher. The study clearly demonstrates that human blood stem cells undergo fundamental metabolic changes as they specialise, age, or become diseased. These shifts can reshape both their identity and behaviour. “This raises intriguing questions about whether targeted nutrition could help preserve stem cell health, and whether metabolic interventions might support leukemia therapies or promote healthy aging,” says Cabezas-Wallscheid.
