Dynamical systems theory explains how cell interactions and reactions create positional information, driving cell differentiation and robust pattern formation. This framework clarifies processes like gastrulation and tissue genesis.

Area of Science:

  • Developmental biology
  • Systems biology
  • Biophysics

Background:

  • Morphogenesis involves complex cellular processes.
  • Understanding cell differentiation and pattern formation is crucial in developmental biology.
  • Existing theories often lack a unified dynamical framework.

Purpose of the Study:

  • To survey the dynamical systems theory of morphogenesis.
  • To explain how intracellular reactions and cell-cell interactions generate positional information.
  • To highlight the role of this theory in understanding cell differentiation and pattern stabilization.

Main Methods:

  • Review of dynamical systems theory applied to morphogenesis.
  • Analysis of intracellular reaction dynamics and cell-cell interactions.

Related Experiment Videos

  • Discussion of specific biological examples like induction, community effect, gastrulation, and artificial tissue-genesis.

    • Main Results:

    • Positional information arises from intracellular reaction dynamics and cell-cell interactions.
    • These dynamics drive cell differentiation and the formation of ordered spatial patterns.
    • Stabilized cellular states lead to robust morphogenesis and irreversible differentiation.

    Conclusions:

    • Dynamical systems theory provides a robust framework for understanding morphogenesis.
    • The theory explains the stability and irreversibility of cell differentiation.
    • Cellular plasticity dynamics are essential for these developmental processes.
