Morphology of cells generated from FL-supplemented BM cultures.

Cells were harvested and cytospins prepared. Cytospun cells were photographed at 400 × magnification. BM cells from C57BL/6 mice were cultured in FL for 9 days alone (A) or stimulated for the final 24 hours of culture with the addition of LPS (B), IFN-α (C), or GM-CSF (D). (E) “Myeloid” DCs cultured in GM-CSF and IL-4 for 7 days.
