Summary
Logic circuits of transcription factors and enhancers that specify cell states in the embryo.
In depth
Davidson mapped sea urchin endomesoderm specification as a network of regulatory interactions. Logic gates and feedback loops produce stable states. Networks are modular and evolvable.
Networks comprise transcription factors, cis-regulatory modules and signals; they explain how cell identity is established robustly. Network changes drive evolution of morphology.
Example: sea urchin skeletogenic mesenchyme network.
Frequently asked questions
What is Developmental Gene Regulatory Networks?
Logic circuits of transcription factors and enhancers that specify cell states in the embryo.
Which area of biology covers Developmental Gene Regulatory Networks, and how advanced is it?
Developmental Gene Regulatory Networks is one of the 54 topics in Developmental Biology. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Cell Fate Determination, Evo-Devo of Body Plans, Pluripotency.
Can you give an example of Developmental Gene Regulatory Networks?
The gene network for heart specification includes Nkx2-5 and GATA4.
What should I learn before Developmental Gene Regulatory Networks?
Work through the Beginner topics in Developmental Biology first, such as Fertilisation, Zygote, Embryo, then return to Developmental Gene Regulatory Networks. Advanced topics assume the Intermediate vocabulary.
What topics are related to Developmental Gene Regulatory Networks?
The closest topics to Developmental Gene Regulatory Networks are Cell Fate Determination, Evo-Devo of Body Plans, Pluripotency, Hox Genes. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Developmental Gene Regulatory Networks?

How is Developmental Gene Regulatory Networks different from Cell Fate Determination?
Developmental Gene Regulatory Networks: Logic circuits of transcription factors and enhancers that specify cell states in the embryo. Cell Fate Determination: Cells commit to specific lineages as signals activate particular genes. Read both side by side and note what each one explains.
How should I study Developmental Gene Regulatory Networks step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Cell Fate Determination and explain the difference aloud. Finally, take the Developmental Biology quiz and come back to this page for any question you miss.
