The movies above are a subset of confocal Z series generated from fresh explanted tissue of mice containing a knock-in of fusion red reporter to the Csf1r locus as well as the Csf1r-EGFP transgene. Most macrophages are both red and green and appear yellow. As the field of view moves inwards from the surface there is a transition from a capsular stellate population. Additional movies are available for download linked to the original publication.
