摘要：

Replicas of freeze-fractured collagen fibrils of rat aorta, dermis, perichondrium (of rib and tracheal cartilage), and peritendineum (of the tail tendon) and of pig cornea show microfibrils which are helicoidally arranged; however, microfbrils have a straight arrangement in the cartilage of rat rib and trachea as well as in that of bovine knee joint and nasal septum. The microfibrils of rat tail tendon collagen also follow a straight course. In thin sections, after the specimens were treated with a 4 M guanidinium chloride solution, the helicoidal arrangement of the microfibrils in the collagen of the aorta and dermis and their straight course in the collagen of the nasal septum cartilage and tail tendon are also demonstrated. © 1979 Academic Press, Inc.
