Hematopoietins

Hematopoietic growth factors include IL-3, IL-7, granulocyte-macrophage colony stimulating factor (GM-CSF), and macrophage CSF (M-CSF).

IL-3: stimulates colony formation of erythroid, megakaryocyte, eosinophil, basophil, and monocyte lineages.

IL-7: is a growth factor for progenitor B and T cells and mature T cells. IL-7 is a crucial cytokine for T cell development and maintenance of T lymphocyte homeostasis.

GM-CSF is a differentiation factor for granulocytic and monocytic cells.

M-CSF is a growth and differentiation factor for macrophages and their progenitors.
