BALF fibroblasts in patients with mild asthma express the fibrocyte markers CD34, CD45RO, and α-SMA. BALF fibroblasts were cultured as described in the method section and observed after approximately 30 days in culture (A). The BALF fibroblasts were fixed in 4% paraformaldehyde and stained with antibodies against CD34 (green), CD45RO (red) and α-SMA (blue) (B). These pictures were merged together with a transmission picture.
