[Homologous articular cartilage transplantation in animal experiments. Preliminary studies on sheep (author's transl)]. 1976

Homologous articular cartilage without subchondral bone instead of the usual osteochondral grafts was transplanted in sheep. The transplants were fixed to the host by a biological tissue adhesive based on fibrinogen clotting. Light- and electronmicroscopic studies showed viable transplants up to 7 months and a stable bony union with the host through endochondral bone formation. A additional external fixation of the joint after transplantation or the use of a conventional cyanoacrylate tissue adhesive failed to achieve positive results. The relations of these preliminary findings for restorative techniques of articular cartilage defects are discussed.

UI MeSH Term Description Entries
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D002358 Cartilage, Articular A protective layer of firm, flexible cartilage over the articulating ends of bones. It provides a smooth surface for joint movement, protecting the ends of long bones from wear at points of contact. Articular Cartilage,Articular Cartilages,Cartilages, Articular
D003487 Cyanoacrylates A group of compounds having the general formula CH2 Cyanoacrylate
D005260 Female Females
D005337 Fibrin A protein derived from FIBRINOGEN in the presence of THROMBIN, which forms part of the blood clot. Antithrombin I
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012756 Sheep Any of the ruminant mammals with curved horns in the genus Ovis, family Bovidae. They possess lachrymal grooves and interdigital glands, which are absent in GOATS. Ovis,Sheep, Dall,Dall Sheep,Ovis dalli
