abstractText | To investigate possible adverse consequences of persistent neutrophil overproduction, mice transgenic for human granulocyte colony-stimulating factor (hG-CSF) were studied for more than 1 year. They showed marked granulocytopoiesis and neutrophilia. Continuous medullary and extramedullary granulocytopoiesis resulted in marked changes in bone and liver. In the liver, haemorrhage and focal necrosis and a few haemangiosarcomas were present, presumably caused by the destructive granulocytopoiesis. Despite the high incidence of lung infiltration by mature neutrophils, lung lesions rarely appeared. Although there was a persistent increase in neutrophils, mortality of the mice did not differ from that of non-transgenic littermates at least within 1 year after birth. Factors other than overproduction of G-CSF and extensive neutrophilia could be required for the development of neutrophil-mediated acute and chronic tissue damage. Copyright 2000 Academic Press. |
