Figure 2From: A cell culture model using rat coronary artery adventitial fibroblasts to measure collagen productionCell Characterization. Cultured rat coronary artery adventitia fibroblasts (LAD) and aortic vascular smooth cells (VSM) (positive control) stained for desmin, α-smooth muscle actin (α-SMA) and vimentin. LAD stained negative for desmin and αSMA and positive for vimentin, a fibroblast marker. VSM stained positive for all 3 proteins. Desmin and α-SMA are specific VSM markers.Back to article page
