References needed

This article does not cite any references. This should be addressed. —Preceding unsigned comment added by 203.206.37.99 (talk) 14:37, 21 March 2009 (UTC)

Epiboly

Epiboly also has a related meaning in the context of wound healing

Epiboly continues after gastrulation has finished; it is therefore considered a separate process

Merger

I agree with the merger of the suggestion of both of the pages Gastrula and Eipo-something. Estridaldrea (talk) 21:59, 22 January 2008 (UTC)

Drosophila

A description of gastrulation in the Fruit Fly, Drosophila, is needed. This finely orchestrated process has emerged as powerful and productive model to study some of the molecular mechanisms that underlay epithelial morphogenesis. —Preceding unsigned comment added by 81.234.204.182 (talk) 07:25, 31 May 2008 (UTC)

Mammals

Why's the section on mammals smaller than the sections on everything else? Sea Urchins? Who cares aboot sea urchins? Can somebody do some work on the mammalian section or at least mark it for improvement?

I'd do it myself but I'm still learning this stuuf. —Preceding unsigned comment added by 134.36.19.25 (talk) 11:37, 24 September 2008 (UTC) human

I care about sea urchins - they're non-chordate deuterostomes, and everything else on the page is a vertebrate. For that matter, why aren't there any protostomes on this page? I came here trying to sort some details of epiboly trends in protstomes vs. deuterostomes. Someone above mentioned fruit flies - that would be a good start. Maybe have something for every phyla, and cut down on the vertebrates a bit? —Preceding unsigned comment added by 154.20.85.215 (talk) 02:43, 16 April 2009 (UTC)

Mesoderm

In the lede the three layers are named the ectoderm, mesoderm, and endoderm. So, why isn't the diagram labelled that way? There is no mesoderm in the diagram and it is instead labelled blastocoel, a word that appears nowhere else in the article. Cottonshirtτ 07:44, 28 June 2013 (UTC)

Merge from Blastopore

I've taken the liberty of merging Blastopore into this because the two articles are both scanty and a student viewing the two wouldn't have a prayer of figuring out the relationship between them. As it is, this is still terribly incomplete... I ought to do something about that. Wnt (talk) 21:55, 20 March 2015 (UTC)

Gastrula link

The word "gastrula" in the 5th paragraph links to the same article. Did someone intend to write up gastrula or link to a definition?

I've removed the link for now, but if someone wants to supply something more elaborate than the definition already in the article, please do so, and restore the link. KC 18:51, 28 March 2016 (UTC) — Preceding unsigned comment added by Boydstra (talk • contribs)

Pictures and words

The text refers to the blastula as containing one layer (of cells?) wheras the diagram shows two "layers" (blue and yellow). The text refers to the gastrula having three layers, wheras the diagram shows four (blue, yellow, green and purple). For non-specialist readers this is baffling. Can someone please explain? LookingGlass (talk) 15:55, 12 May 2016 (UTC)

Incomplete generalization?

The article seems set out to describe gastrulation as a general thing. However the bulk of it refers to amniotes implying that there is another form of gastrulation for anamniotes. I don't think this is the case. If it isn't then the heading needs changing as it implies there is, and if there is then som,e mention should be made to it.

The section on amniotes does not mention the blastocyst of human embryology. The blastocyst comprises: Embryoblast (ICM), Pellucid zone, Trophoblast, and Blastocyst cavity. If the Trophoblast cells constitute one "layer" then are the cells of the embryoblast discounted as a "layer"?

Thanks for pointing this out, LookingGlass. There are very few active anatomy editors. As you know, the best way to make any change on Wikipedia is to be bold and make that change. I will try and help out out as much as I can if you need any support. Cheers --Tom (LT) (talk) 22:23, 13 May 2016 (UTC)

Hi Tom (LT), I generally try to edit where I find confusion that I can untangle and/or when in grappling with this I find apparent errors or misunderstanding, but that's pretty much it. I'm not a subject matter expert so, as with the queries I made above, I'm not in a position to go much further. Thank you for your encouragement. It's appreciated. LookingGlass (talk) 06:35, 15 May 2016 (UTC)

This is actually a problem with this article. There is a LOT of diversity in gastrulation across the animal kingdom, and it's not incorporated into this article. I'm going to take a shot at it. MangoldOrganizer (talk) 12:32, 25 March 2017 (UTC)

Merger proposal March 2017

Early stages of embryogenesis of tailless amphibians is basically frog gastrulation. Previously, this article was based mostly on chick gastrulation, with some protostome/deuterostome thrown in there. To illustrate the general principles, mechanisms, and diversity of gastrulation in the animal kingdom, I propose that it be merged into this article. — Preceding unsigned comment added by MangoldOrganizer (talk • contribs) 12:30, 25 March 2017 (UTC)

• Oppose on the ground that moving the Gastrulation section from Early stages of embryogenesis of tailless amphibians will leave that article quite bare. I suggest that, instead, the amphibian gastrulation section has a template:main to the Early stages of embryogenesis of tailless amphibians page. Klbrain (talk) 18:10, 9 August 2018 (UTC)
• Oppose per Klbrain. There is too much content to merge here. If we are just talking about frogs then MangoldOrganizer perhaps that article can be moved to Frog embryogenesis so it's scope is a bit broader, and then linked to from some other articles as suggested above. --Tom (LT) (talk) 23:16, 9 August 2018 (UTC)

Review

I think the article is well written but could use more updated sources. The introduction is very useful and informative. The sectioning is also useful for the different species. The linked words for also helpful. They used a number of sources, however they are older sources. The page could be improved with more recent information.
