5x expanded by Mannintg (talk), Dickhitch (talk), Tadahhla (talk). Nominated by Smallman12q (talk) at 02:08, 5 April 2013 (UTC).

  • Before expansion, the article was 1800 characters. After expansion, it was about 7200 characters, four times the original size. For DYK, the requirement is 5x expansion, so another 1800 characters are needed. Given the numerous scholarly articles I've found, I think this can be easily achieved. Moreover, the reference display is odd, as the notes section begins with a set of numbers. I'd also prefer to see a different reference for the first statement in the article, that is a scholarly or scientific work instead of Encyclopedia Britannica. Mindmatrix 15:45, 7 April 2013 (UTC)
  • I believe that these issues have been addressed by my last round of edits. Mannintg (talk) 21:00, 9 April 2013 (UTC)
  • The article is still too short; it is now 7802 characters, but should be about 9000 to pass DYK (references, notes, infoboxes etc. are not included in the count). See guideline A3 for info about counting characters in an article. Basically, you need 3-5 more moderately sized paragraphs with sources. Mindmatrix 15:05, 11 April 2013 (UTC)
  • Mindmatrix's mathematics are incorrect. Using DYKCheck, I found out that before expansion began, this article had 831 prose characters. Now, it has 7682 prose characters. It has been expanded well over five times, thus it meets the requirement. Also, I found the first hook to be more intriguing than ALT1. But this article has other two problems that require attention: the first reference needs to be properly inserted, instead of just a bare URL. And QPQ still needs to be done. —♦♦ AMBER(ЯʘCK) 10:46, 23 April 2013 (UTC)
  • Oh goodness. I've rechecked, and it appears that the tool I used double-counted everything in this instance. Instead of 1800 as I first reported, it should have given me 900. My humblest apologies to all involved. I will review new content in the next day or so. Mindmatrix 15:51, 23 April 2013 (UTC)
  • There is actually no requirement for a QPQ here: the nominator is not one of the creators. It would be nice if someone did a QPQ review, but it is not necessary for approval. BlueMoonset (talk) 03:39, 27 April 2013 (UTC)
The other issue is still unresolved though. —♦♦ AMBER(ЯʘCK) 14:35, 28 April 2013 (UTC)
  • To be clear, there are two issues related to the same (first) reference in the article: first, that it is a bare URL, something forbidden by DYK rules, and second, Mindmatrix would prefer a different reference altogether that didn't use Encyclopedia Britannica but rather "a scholarly or scientific work". For a DYK, I think the Britannica source can probably serve, but the bare URL must be fixed. BlueMoonset (talk) 16:28, 28 April 2013 (UTC)
  • I've reviewed the article fully, which has a few minor issues to resolve but is otherwise in good shape. First, the article states "blastomeres behave as pluripotent stem cells which can migrate down several pathways, depending on cell signaling"; is this referring specifically to TGF beta signaling pathway, which is mentioned in the source, or all signaling? Regarding the statement "in vitro fertilisation involves implantation of a blastula into a mother’s uterus", the source seems to say this is one of several options. Are there relevant WP links for the terms "EP-cadherin" and "XB/U cadherin"? (Not as important, but most readers won't know what these are, and I couldn't find mention of them on the cadherin article.) Please disambiguate the links to superovulation and eye field, and please use {{cite encyclopedia}} for the first citation. I will assume good faith on the sources I cannot access, and the sources appear to be reliable. Everything else satisfies the criteria for DYK. Mindmatrix 14:21, 29 April 2013 (UTC)
    • First, the article states "blastomeres behave as pluripotent stem cells which can migrate down several pathways, depending on cell signaling"; is this referring specifically to TGF beta signaling pathway, which is mentioned in the source, or all signaling?
  • Signaling in general. A number of pathways/environmental stimuli can provide/serve as differentiating factors pluripotent stem cells.
    • Regarding the statement "in vitro fertilisation involves implantation of a blastula into a mother’s uterus", the source seems to say this is one of several options.
  • It's done up to and including the blastula/blastocyst stage. See Embryo culture.
  • Done.
    • Are there relevant WP links for the terms "EP-cadherin" and "XB/U cadherin"?
  • Doesn't look like it. You could make red links if you want.
