Figure 3. RAMP2 expression in cryostat sections of human thymic tissue.

Sections were incubated with an antibody against RAMP2. RAMP2 is expressed in the cortical (A) and medullary (B) epithelial compartments, in Hassal's bodies (C) and in blood vessels and their related mastocytes (arrow in panel D). When, for control purposes, the primary antibody was replaced by a non-immune normal goat serum or by primary antibodies pre-absorbed with antigen excess, no reactivity was observed (not shown in the figure). Original magnification ×100. C: cortex; M: medulla; HB: Hassal's body.
