VEGFA and sarcoidosis: In particular, qRT-PCR in 10 sarcoidosis and 10 control lung samples revealed abundant VEGF expression (Figure 1B) in sarcoidosis mediastinal lymph nodes compared to controls evidence that was further corroborated by semi-quantitative computerized immunohistochemistry analysis in tissue microarray sections of sarcoidosis patients revealing a diffuse cytoplasmic strong staining intensity, indicating increased VEGF expression (Figure 3A-F).
