title: An autoradiographic study of bone grafts in small animals.
abstract: Bone remodelling was studied in allografts and isografts by means of autoradiography. Collagen and proteoglycans of the organic bone matrix were labelled with H-3 amino acids and S-35 sodium sulphate. The principles of primary bone formation are followed in graft remodelling as well. Matrix breakdown and reformation are carried out by mononuclear cells. Components of the original matrix can be seen in osteoclasts, perivascular cells, osteoblasts, young osteocytes, and in new bone. The label allows tracing of these components and proves their reuse.
