    Abstract
    A molecular recombinant of Rous sarcoma virus and murine amphotropic leukaemia virus, src(MoMuLV), where the avian src oncogene has been placed under the influence of a murine virus promoter sequence, has been reported. Infection of long-term marrow cultures with this virus led to a dramatic change in the relative numbers of stem cells, granulocyte-macrophage progenitor cells and mature cells found in normal haematopoietic cell development. However, although the balance between self-renewal, differentiation and development was disturbed, injection of the cultured cells into irradiated syngeneic recipients did not lead to the development of leukaemia. Thus, although the control had been 'loosened', the host regulatory mechanisms were sufficient to impose a restraint on unlimited growth of the cells. We now show that the stem cells from the src-infected cultures show a remarkably increased capacity for self-renewal in vitro in situations which are inimical to the maintenance of self-renewal in normal uninfected stem cells and that self-renewal/differentiation can be modified by the culture conditions.
