Modelling the long QT syndrome with induced pluripotent stem cells.

abstract：:Chronic myelogenous leukaemia (CML) is a clonal disease arising from malignant transformation of pluripotent hematopoietic stem cells. In most cases, it is characterized by the presence of the Philadelphia (Ph1) chromosome (22q-) which results from a reciprocal translocation between chromosomes 9 and 22 (refs 1-3). In...
