[Mechanical stresses as factors in the autoregulation of morphogenesis].
Since morphogenetic processes are nonlinear, feedback must be essential for their regulation. Two concepts of feedback in morphogenesis are developed: 1) inhibition by diffusing morphogenetic substances and 2) action of mechanical strain resulting from morphogenetic movements. The data on the role of mechanical strain in formation of integral structure of embryonic tissues, primary demarcation of embryonic epithelia and mesenchymal rudiments and bending of epithelial layers are presented. Evolutionary aspects of morphogenetic role of mechanical strain and its possible use in applied biotechnology are discussed.
