Previous studies have shown that retinoic acid ( RA ), similar to tumor necrosis factor-alpha ( TNF-alpha ), can act as a bifunctional regulator of the growth of bone marrow progenitors , in that it can stimulate granulocyte-macrophage colony-stimulating factor (GM-CSF)- or interleukin-3 (IL-3)- induced GM colony formation , but potently inhibit G-CSF -induced growth .
