Figure 2. FRCs connect the MZ to the PALS at the MZBC.
Spleen cryostat sections from HuCD2 GFP (blue) mice were stained for ERTR-7 (green = FRC-derived matrix protein), MOMA-1 (red, panels A and C) or Desmin (panel B) and imaged using confocal microscopy. In panel C, the insert shows a higher magnification of 2 MZBCs. Arrowheads point to the location of MZBCs while “B” indicates the presence of B cell follicles. This picture is representative of 3 different experiments. See also Movie S1.
