Modern Approaches to Studies of New Osteogenic Biomaterials on the Model of Regeneration of Critical-Size Cranial Defects in Rats

详细

Osteoinductive characteristics of new osteoplastic materials based on demineralized bone matrix of xenogenic origin with high and controlled degree of purification were studied on the model of regeneration of critical-size cranial defects in rats using modern approaches, including histological analysis, evaluation of morphological parameters of the bone tissue obtained by micro-computed tomography, and estimation of bone tissue growth rate using in vivo fluorochrome label. Demineralized bone matrix and, to a much greater extent, its activated form containing modified recombinant growth factor rhBMP-2 with high content of the dimeric form exhibited osteoinductive activity.
