In order to address your feedback fully, we felt it necessary to split Figure 7. The data contained in the original Figure 7 is now split between Figure 7 (deals with CD14 and CD68 only) and Figure 8 (deals with CD11b and CD36).
Figure 7b is not very credible, when U937 become macrogphages adhere to the plate and assume the morphology of a macrophage. the figure is not clear and not well visible.
