Summary
Behaviour and fate of the transplanted articular cartilage were studied in 180 adult rabbits, using the scanning electron microscope, histological staining and autoradiographic examination.
The junction between the host cartilage and the transplanted cartilage was covered with thin connective tissue layers which extended from the edges 4 weeks after transplantation.
After the 24th week of transplantation the cartilage tissue appeared to be degenerating at the periphery of the graft.
However, in the middle portion of the graft surviving cartilage cells were observed using 35S autoradiography.
Résumé
Comportement et évolution du cartilage articulaire transplanté ont été étudiés chez 180 lapins adultes par microscopie électronique, colorations histologiques et autoradiographies.
Quatre semaines après la transplantation, une fine couche de tissue conjonctif qui s'étend depuis les bords recouvre la jonction entre le cartilage du receveur et le cartilage transplanté.
Vingt-quatre semaines après la transplantation, le tissu cartilagineux commence à dégénérer à la périphérie du greffon. Cependant, à la partie centrale de celuici, des cellules cartilagineuses survivantes peuvent être mises en évidence grâce à l'autoradiographie au S35.
