Figure 1.
SHIP-deficient mice lack MZBs and MZMOs are displaced to the red pulp. (a) FACS® profiles of single cell suspensions from the spleen of SHIP-heterozygous (SHIP+/−) and -deficient (SHIP−/−) mice. MZBs were measured as the CD19+, CRIhigh, and CD23low population. The numbers shown represent percent of CD19+ cells for the depicted gates as an average of five mice. Numbers for the follicular B cells are shown for comparison. (b) Representative immunohistochemical analysis of above listed mice. At least four serial sections from each mouse were stained for MOMA-1+ (blue, top) metallophilic macrophages or MARCO+ MZMOs (blue, bottom). Sections were also stained for B220 (brown) to show the positioning of the follicle. ×10.
