Electron microscopic radioautography was used to study the osteogenesis during the replacement of bone tissue defects by graded distraction osteosynthesis in 12 patients with open fractures of the tibia. In the early stages of reparative tissue formation, the cells that intensely synthesized DNA and DNA were located exceptionally in the vascular walls or near them. The authors assume that vascular cells, most probably pericytes, are a basic source of the origin of the reparative tissue, turning firstly to fibroblast-like cells and then to osteoblasts.
