Fig. 7. Localisation of integrin _E (CD103) in the human thymus. (A) Staining of thymus cryostat sections with the antibody against CD103 revealed that the cell surfaces of individual thymocytes (arrowheads) within the medulla (m) are strongly labelled. Note that only a few thymocytes within the cortical region (c) were stained with the CD103 antibody. (B) Control staining was performed with the antibody W6/32. HK, an inactive variant of the anti-MHC class I antibody W6/32.HL. No background staining was observed with this antibody. Bar, 100 µm.
