[Peculiarities of regenerative processes after the plasty of osteochondral defects with combined cell-tissue grafts on the basis of autologous and allogeneic cell cultures from costal cartilage tissue].

From a position of in vivo regenerative medicine, the efficacy of plasty of osteochondral defects of the articular surface was evaluated in rabbits. The combined cell-tissue grafts were used with the demineralized spongy bone as a biomatrix and autologous or allogeneic cells from the rib cartilage tissue. Morphofunctional characteristics of the cell cultures obtained were studied using morphological, histochemical, immunohistochemical and flow cytometric methods.
