Increased cell proliferation and PDGFR-βexpression during vascular remodeling.
Representative anti-PDGFR-β staining (a,b,c) and anti-PCNA staining (d,e,f) for proliferating cells of contralateral (a,d) and ligated carotid arteries (b,c,e,f). Internal elastic lamina (IEL) is marked by a black arrow. Arrowheads indicate the cells positive for antibody staining. L identifies the lumen.
