Researchers investigate the role of PlGF in mice with chronic myeloid leukemia

Chronic myeloid leukemia (CML) is a particular form of leukemia or cancer of the bone marrow, which can be treated with targeted imatinib. However, in some cases this medicine has no effect. Researchers at the VIB Vesalius Research Centre, K.U. Leuven, under the direction of Peter Carmeliet, have investigated the role of placental growth factor (PlGF) in mice with CML.
