[Regenerative myogenesis of the leg muscles during experimental lengthening]

Regenerative myogenesis of an extremity regenerating by bilocal distraction osteosynthesis according to Ilizarov has been studied by light end electron microscopy. During the osteosynthesis, the action of the factor of mechanical tension is observed. Muscles elongate because myogenic cells incorporate into muscular fibers in the area of their attachment to dense connective tissues. The data obtained confirm the role of mechanical tension in spatial organization of cells, in morphogenetic and formation processes.
