High-power image showing immunohistochemical staining for CD34 of a skin biopsy from a patient with nephrogenic systemic fibrosis
A high-magnification image with immunohistochemical staining reveals abundant elongated cells that express the cell surface antigen CD34 (brown) and produce the protein procollagen I (magenta). This combination of findings identifies the cells as circulating fibrocytes.
