Fig 3. Macrophage yield from M-CSF-stimulated bone marrow cultures is reduced in ERK1/2 mice.

2.5×10⁷ bone marrow cells from ten individual mice of each genotype (LysM and ERK1/2) were cultured for 7 d in 50 ml D10F with 25% LADMAC cell conditioned medium, and macrophage yields were determined by cell count with Trypan Blue exclusion.
