a model system with myeloid blood cells has shown that ( i ) normal blood cells require different proteins to induce cell multiplication ( growth inducers ) and cell differentiation ( differentiation inducers ) , ( ii ) there is a hierarchy of growth inducers as cells become more restricted in their developmental program , and ( iii ) a cascade of interactions between proteins determines the correct balance between immature and mature cells in normal blood cell development .
