Provisionally mechanisms of fractal structures formation of internal organs in human embryogenesis
Aim. To determine the universal mechanisms of organ formation in human embryogenesis. Materials and methods. We have studied the definitive kidneys, the adenohypophysis and small intestine. 118 embryos (Carnegie stage 12-23) were studied by light and electron microscopy. Results. We have compared the development of these organs and identified common mechanisms of organogenesis. We concluded that such mechanisms as the intussusception and traction are palingenetic signs and provisionally universal formative mechanisms of germs and their structural and functional units on the principle of self-similarity.
