Modelling morphogen gradients and pattern formation in development

Introduction to Systems Biology in Developmental Biology:
- Systems biology integrates computational, mathematical, and experimental approaches to
study complex biological systems.
- Application: In developmental biology, systems biology provides a holistic view,
emphasizing interactions and feedback mechanisms.

Morphogen Gradients and Pattern Formation:
- Concept of Morphogens: Signaling molecules
that form concentration gradients and regulate cell
fate determination.
- Pattern Formation: Morphogen gradients
orchestrate spatial organization, influencing cell
differentiation and tissue patterning.
- Examples: French Flag Model illustrates
how morphogen gradients define distinct cell
populations.

Turing Patterns and Morphogenesis:

- Turing Instabilities: Alan Turing's
theoretical concept elucidates how stable
equilibria can become unstable solely
through diffusion.
- Biological Relevance: Turing
patterns underlie various spatial patterns
in biology, including animal coat
patterns.
- Significance: Reveals counter-intuitive mechanisms driving pattern formation without
requiring pre-existing patterns.
