Figure 6From: Calcitonin gene-related peptide stimulates proliferation of alveolar epithelial cells Immunohistochemistry for Proliferating Cell Nuclear Antigen. Histological examination indicated proliferation of alveolar epithelial cells, and PCNA immunohistochemical staining represented that the nuclei of these cells were positive in the group administered rhCGRP (B, C), and few positive nuclei were observed in the control group (A). The bars represent 100 μm.Back to article page
