STUDIES ON SLICES AND ISOLATED CELLS FROM FRESH OSTEOARTHRITIC HUMAN BONE

Abstract

1. The use of the Metals Research Macrotome for cutting 100 μ thick sections of fresh, unfixed specimens of arthritic human femoral heads and normal goat condyles is described. 2. A technique for isolating living cells from these slices by decalcification followed by enzymic digestion is reported. 3. The microscopic appearances of the fresh slices, the decalcified slices and the isolated cells as seen by incident or transmitted fluorescent lighting, by phase-contrast microscopy, by scanning electron microscopy and by histological and cytological techniques are illustrated. 4. These techniques might be applicable to the examination of biopsy specimens of pathological bone or to basic research on bone cells.
