Mitofusin 2 maintains haematopoietic stem cells with extensive lymphoid potential

Haematopoietic stem cells (HSCs), which sustain production of all blood cell lineages, rely on glycolysis for ATP production, yet little attention has been paid to the role of mitochondria. Here we show in mice that the short isoform of a critical regulator of HSCs, Prdm16 (refs 4, 5), induces mitofusin 2 (Mfn2), a protein involved in mitochondrial fusion and in tethering of mitochondria to...
