Transmission electron microscopy of collagen fibrils from bovine ligament and tendon. Representative transmission electron microscopy images showing slight distinctions between collagen fibrils between ligament (ACL) and tendon (QT) (A). Scale bar is 100 nm. Collagen fibril diameter plot illustrates bimodal distribution in both tissues (B). Fibril density, mean fibril area and fibril area fraction graphs illustrate several subtle distinctions between the tissues (C).
