Mouse aortic ring embedded in a fibrin matrix. The confocal image shows a ring (∼0.2Tm in width) cut from a mouse aorta and embedded in a fibrin matrix. It was fed with growth medium containing no proangiogenic growth factors; consequently, endothelial cell sprouts have not grown. Colors: DAPI (blue), α-smooth muscle actin (red), BS1 lectin-FITC (green). Image taken from the protocol by Baker et al.
