Peculiarities of Osteogenesis by Periosteal Cells after Experimental Ectopic Transplantation.

We carried out a comparative study of the features of osteogenesis from the progenitor osteogenic periosteal cells in rabbit and human. At the initial stages, high osteogenic potential of both human and rabbit periosteal cells was observed. However, at the later stages, the cell response favors resorption of the new bone tissue formed from periosteal cells in rabbits, but does not affect the bone tissue formed from human progenitor osteogenic periosteal cells. These functional characteristics of rabbit periosteal cells should be considered when planning the experiment.
