Figure 5From: Calcitonin gene-related peptide stimulates proliferation of alveolar epithelial cells Histopathology of CGRP treated rat lung. Recombinant human CGRP (rhCGRP) were administered into Wister rat lung by intratracheal instillation. Proliferation of alveolar epithelial cells and interstitial thickening were observed in the rhCGRP-exposed group (B, C) compared with those in the control group (A) 7 days after CGRP exposure. The bars represent 200 μm.Back to article page
