Which of the following cytokine act as a specific hematopoietic growth factor of Eosinophils?

Growth factors cause cells in one or more of the committed cell lines to proliferate and mature. IL 5 stimulates eosinophils specifically. IL 4 stimulates basophils. IL 1 and 3 stimulates erythrocyte, granulocyte, megakaryocyte and monocyte. Erythropoietin stimulates erythrocyte growth. G-CSF stimulates growth of granulocytes. GM-CSF stimulates growth of erythrocyte, granulocyte and megakaryocyte. M-CSF stimulates growth of monocyte. Thrombopoietin stimulates growth of megakaryocyte.
