CXCL12⁺ cells of stromal morphology are present in human myelolipoma and coexpress FOXC1. (A) Representative images of CXCL12 standard IHC staining (brown) of human myelolipoma samples corresponding, from left to right, to patients I, C, and D (see Table 1 for details). Scale bars correspond to 200 μm and 100 μm in the top and bottom panels, respectively. (B) Double chromogenic immunohistochemical stain for CXCL12 (pink) and FOXC1 (light blue) in human myelolipoma, BM, healthy adrenal gland, and adrenal adenoma. Scale bar represents 30 μm at all instances.
