Kirkby1, Lucinda Low1, Junxi Wu1, Eileen Miller1, Jonathan R. Seckl1, Brian R. Walker1, David J. Webb1, Patrick W. F. Hadoke1 1 Ex vivo analysis of arterial lesions from animal models of cardiovascular disease classically relies on histological and immunohistochemical techniques. These provide 2-dimensional measurements in 3-dimensional lesions. This manuscript describes the generation of arterial lesions for quantitative analysis in 3-dimensions using optical projection tomography.

This isolation method allows simultaneous purification of three multipotent precursor cell populations respectively from three structural layers of blood vessels: myogenic endothelial cells from intima, pericytes from media, and adventitial cells from adventitia.
