In FCS- liquid-suspension culture supplemented with saturating Ep level and low-dose IL-3 /GM-CSF , adult HPC undergo unilineage erythropoietic differentiation : Here again, treatment with high-dose RA induces a shift from the erythroid to granulocytic differentiation pathway .
 ( cell type: HPC, None) , ( protein: Ep, None) , ( protein: low-dose IL-3 /GM-CSF, None) , ( protein: /GM-CSF, None) , ( protein: IL-3, None) , ( cell line: FCS- liquid-suspension culture, None)
