[Ectopic induction of bone and cartilaginous tissue in diffusion chambers in adult rabbits under the effect of ground bone tissue].

The possibility of induction of bony and cartilaginous tissues in the diffusion chambers inserted in the abdominal cavity of adult rabbit under the influence of crushed bone was shown. The induction occurred when the crushed bony tissue moistened with blood was autotransplanted in the chambers together with the crushed muscle. No formation of tissues do novo occurred in the chambers with the crushed bony tissue moistened with blood only. The formation of atypical islets of bony tissue was observed from time to time in the connective tissue capsule overgrowing the diffusion chambers. The bony and cartilaginous tissues were found neither in the chamber, nor on its surface when the empty diffusion chambers were inserted. The comparison of these results with the data obtained earlier allows to conclude that the crushed bony tissue is an inductor rather than a source of ectopic osteogenesis. In those cases when the bony and cartilaginous tissues formed de novo, the connective tissue elements of the crushed muscle were their source.
