Abstract

Bad blood from fat cells Adult bone marrow contains numerous adipocytes, whose numbers correlate inversely with the haematopoietic activity. Disorders of excess haematopoiesis, such as pernicious anaemia and leukaemia, are typically accompanied by haematopoietic infiltration of the fatty marrow of the long bones. It has been unclear whether adipocytes participate in haematopoietic regulation or simply expand to fill marrow space. The answer appears to be that far from making up the numbers, fat cells play a critical physiological role in the bone marrow microenvironment. Experiments in mice show that adipocyte-rich marrow contains fewer blood-forming stem cells and progenitors than adipocyte-poor marrow. Genetically 'fat-free' mice and mice treated with a drug that blocks adipocyte production generated new blood cells more quickly than wild-type animals after a bone-marrow transplant, suggesting that blocking marrow adipogenesis may enhance haematopoietic recovery in clinical bone-marrow transplantation.
