Scope - 2005 - animals or mammals
This article is very informative, but it deals only with mammalian development, blastocysts are exclusive to mammals. They can be, roughly, seen as the equivalent to the blastula in mammals, but they are not blastulas. I think this article should: if this is ok with everyone, i can try and do it (but starting tomorrow by night) --Tycho 20:50, 5 Feb 2005 (UTC)
 * be renamed "mammalian embryogenesis" or something like that, blastocyst redirecting there.
 * a new embryogenesis article should deal with general embryogenesis, with morulas, blastulas, gastrulas, blastiocysts, etc. explaining the differences, which stage follows after each, etc.


 * Perhaps you should keep this page as a disambiguation page and make mammalian embryogenesis a new page. Embryogenesis can then link to mamamalian, plant and drosophila embryogenesis. --nixie 23:50, 5 Feb 2005 (UTC)


 * I have moved the page to mammalian embryogenesis to keep its histoty page, this talk page wasn't moved along with it.--Tycho 22:44, 6 Feb 2005 (UTC)

Hmm five years on and - either the page was moved back, or the page transformed back into a poorly structured article on mammalian embryogenesis(mostly, at least from "formation of the blastula" onwards). I doubt I'll get round to changing that though... Sean Heron (talk) 07:35, 7 February 2011 (UTC)

spelling mistake?
Cells start mayor differentiation processes, losing their pluripotentiality.

shouldn't mayor be major?

-where is the article's image? i thought i've seen it before but it got lost..

=
= I believe the illustration on this page has some errors. The cells labeled ectoderm are actually the epiblast -- They will later become ectoderm after the primitive streak forms and gastrulation starts. The cells labeled endoderm are actually hypoblast celss -- They will be replaced by cells that migrate from the primative streak and THEN become endoderm. The layer of cells labeled mesoderm, is technically mesoderm but it is extraembryonic mesoderm -- it will form the chorion (and therefore part of the placenta). The embryonic mesoderm will be formed from cells in the primative streak and is located between the embryonic ectoderm and embryonic endoderm. Other than these errors the illustration is very clear and easy to understand -- is it possible for it to be corrected? --Dbrouse 22:18, 22 August 2006 (UTC)

GA Nominated, 2006 - not a clear pass or fail

 * GA review (see here for criteria)


 * 1) It is reasonably well written.
 * a (prose): b (MoS):
 * 1) It is factually accurate and verifiable.
 * a (references): b (citations to reliable sources):  c (OR):
 * 1) It is broad in its coverage.
 * a (major aspects): b (focused):
 * 1) It follows the neutral point of view policy.
 * a (fair representation): b (all significant views):
 * 1) It is stable.
 * 2) It contains images, where possible, to illustrate the topic.
 * a (tagged and captioned): b lack of images (does not in itself exclude GA):  c (non-free images have fair use rationales):
 * 1) Overall:
 * a Pass/Fail:
 * a Pass/Fail:

In short:

The lead is awkward and a poor introduction to the article, and the rest of the text is somewhat weak. It uses only two references, neither of which is particularly notable. It fails to put the process in context - not even a link to reproduction? Meiosis? Gastrulation section is biased towards Deuterostomes.

Needs a lot of work, I fear, but it is a good start. Adam Cuerden talk 11:24, 31 October 2006 (UTC)

The definition of delamination is weak. Needs better wording. —Preceding unsigned comment added by 91.23.75.62 (talk) 12:40, 8 December 2007 (UTC)

embryology
Maybe, instead of (or additional to) showing the drawing which illustrates the cleavage, we could provide an example for this developmental stage? This WikiCommons movie should do it. Any comments/suggestions? Ptrrupprecht (talk) 16:41, 29 April 2013 (UTC)

If this article is only about animal embryonic development why is it called 'Embryonic Development' and not 'Animal Embryonic Development'.
The 'About' info at the top of the page currently states:

"This article is about embryogenesis of all animals. For human embryonic development, see Human embryonic development. For plant embryogenesis, see Plant embryogenesis."

Surely, then, this page should be called either "Animal Embryonic Development" or "Animal Embryogenesis".

Currently, it is called "Embryonic Development".

For consistency, maybe it would be nice if all 3 pages (Animal, Plant, and Human) used either "Embryonic Development" or "Embryogenesis" in the title.

UPDATE:

I changed the name to Animal Embryonic Development and someone changed it back calling it an "Unnecessary inclusion of 'animal'" and saying "See talk page", but I can't see anything on the talk page explaining this reversion.

Since there is a page about plant embryo development called 'Plant embryogenesis' and this page is specifically about animals, why shouldn't it have 'animal' in the title? It is not just animals that have embryos.

What is happening inside the cells
This article seems to just cover what is visible through a microscope. What causes the movement of cells, formation of 2 or 3 layers of different cell types, and further differentiation ? What article(s) in Wikipedia describe the differentiation at the molecular level ? Is it an epigenetic process ? What are the details ? - Rod57 (talk) 23:07, 5 July 2024 (UTC)
