Haematopoietic stem cells (HSCs) are very sensitive to energetic and oxidative stress, and modulation of the balance between their quiescence and proliferation is needed to respond to metabolic stress while preserving HSCs' long-term regenerative capacity. Here, and in two accompanying studies, it is shown that the tumour suppressor Lkb1 has a crucial role in maintaining energy homeostasis in haematopoietic cells.
