Figure 2From: Expression of Hypoxia-Inducible Factor (HIF)-1a-Vascular Endothelial Growth Factor (VEGF)-Inhibitory Growth Factor (ING)-4- axis in sarcoidosis patientsHIF-1a immunohistochemical staining in sarcoidosis lung samples . Representative tissue microarray section immunostained with monoclonal antibody HIF-1a demonstrating diffuse cytoplasmic reaction of weak intensity in epithelioid cells within granulomas (arrows) derived from sarcoidosis patients (n=37) compared to control lung samples (n=24) (E). Scale bars in panel A: 100μm, B and C: 25 μm and D, E: 10 μm. Immunohistochemical findings were confirmed by computerized image analysis (F).Back to article page
