Last fall, we published an article in the journal Leukemia documenting that indeed NB4 cells could be stimulated to differentiate into monocyte/macrophages by combinations of phorbol esters, 1,25 dihydroxyvitamin [D.sub.3], and macrophage colony stimulating factor (MCSF).
For instance, SF are a source of chemokines and also of hematopoietic growth factors such as monocyte chemoattractant protein 1 (MCP-1), macrophage colony stimulating factor (M-CSF), IL-34, or granulocyte-macrophage colony-stimulating factor (GM-CSF) that can support monocyte migration and macrophage activation in the synovium.
In general, these methods utilise M-CSF (macrophage colony stimulating factor; CSF-1) to differentiate bone marrow derived progenitors, followed by priming with various stimuli.
