Isolation, characterisation, growth and culture of endothelial cells from the rat aorta

Rat aortic endothelial cells have been isolated by the explantation technique and grown in culture. They have been identified morphologically using standard staining techniques, biochemically by identification of angiotensin convertase and have been positively stained for Factor VIII-related antigen by immunofluorescence using both anti-human and anti-rat Factor VIII antibodies. The explantation technique is a successful alternative to enzyme digestion which is not applicable to rat aortic endothelial cells because of the nature of their attachment to the subendothelial layer.
