Summary
Aggregates of stem cells that self-organise to mimic early embryo axis formation.
In depth
Aggregates of mouse or human stem cells under controlled signals break symmetry, elongate and form axial structures and somite-like segments. They allow study of early development without embryos.
Gastruloids self-organise to form germ layers, body axes and somites in a dish. They reduce the need for embryos and allow high-throughput studies, but lack extraembryonic tissues.
Key idea: embryo-like structures show how development can self-assemble.
Frequently asked questions
What is Gastruloids?
Aggregates of stem cells that self-organise to mimic early embryo axis formation.
Which area of biology covers Gastruloids, and how advanced is it?
Gastruloids 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 Somites, Pluripotency, Totipotency.
Can you give an example of Gastruloids?
Gastruloids show oscillations of the segmentation clock.
What should I learn before Gastruloids?
Work through the Beginner topics in Developmental Biology first, such as Fertilisation, Zygote, Embryo, then return to Gastruloids. Advanced topics assume the Intermediate vocabulary.
What topics are related to Gastruloids?
The closest topics to Gastruloids are Somites, Pluripotency, Totipotency, Model Organisms in Development. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Gastruloids?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Gastruloids. To practise the whole of Developmental Biology, use the Developmental Biology quiz.
How is Gastruloids different from Somites?
Gastruloids: Aggregates of stem cells that self-organise to mimic early embryo axis formation. Somites: Blocks of mesoderm beside the neural tube that give rise to vertebrae and muscle. Read both side by side and note what each one explains.
How should I study Gastruloids 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 Somites and explain the difference aloud. Finally, take the Developmental Biology quiz and come back to this page for any question you miss.
