Merger

Oppose merge. There would not be room to go into detail on this particular germ layer in the general germ layer article if they were merged.--Gmosaki 13:55, 14 May 2006 (UTC)[reply]

Assignment

Tyler7810 and I (forabettalorretta) are collaborating to improve this article, and of course we extremely welcome to insight/criticism/suggestions/edits/ or any other comments from fellow Wikipedia contributors. We orginally set out to create sub sections for Early Development, History of Research, Ectoderm Differention, Current Research, and Related Diseases. We think that we may omit the Current Research section, for two reasons: one being that originally we had a third collaborator to help with the workload as part of a class assignment but unfortunately she dropped the class, and secondly we think it could be considered the least "encyclopedic" of the sections we currently have planned.

For the "Early Development" section of the article, we plan to give a detailed analysis at the cellular level of how the ectoderm materializes from fertilization. Here we will introduce the concept of the germ layers and how the ectoderm in particular, forms relative to the other two germ layers. This will be followed by the next section, which describes the ectoderm's next course of action, titled "Ectoderm Differentiation". For this part, we will focus on how the biological events of the ectoderm during the later stages of development, including the fates of the cells of the ectoderm up to the mature stage and touch a little bit on the fates of the cells for the other two germ layers. The next section will be titled "History of Research". At the very least, we would like to discuss the first discoveries of the formation of the ectoderm. Depending on the literature available, it would also be nice to give some other important findings about or relating to our topic. We are still unsure weather this section will come after "Ectoderm Differentiation" or before "Early Development". Finally, our last section will focus on the ectodermal diseases. As of right now, the major disease that has a lot of literature is ectodermal dysplasia. Since there are many different subtypes of this disease, a lot of this section will most likely deal with the more prevalent of the subtypes. If possible, we would like to include other early diseases of the germ layer.

Thus, at the moment we hope to make the Ectoderm article a stronger article first by elaborating on some of the historical experiments carried out which elucidated some key facts about the ectoderm Then we will detail more of the specific interactions that it is involved in during early embyronic development and what happens to ectodermal cells as they differentiate into more specific cell lineages. Lastly, we want to include some summary information on disease related to ectodermal abnormalities. As the research and improvement of the page continues, sections may be changed or be modified, which we will note on this talk page. --forabettalorretta forabettalorretta 02:44, 20 March 2013 (UTC) Tyler7810 (talk) 00:42, 22 March 2013 (UTC)[reply]

whats the oocyte picture in here for?

Do you have a plan for that picture? Needs a better legend, and could be bigger. Maybe a better picture if the goal is to show 3 layers in an early embryo? Hakeleh (talk) 22:42, 3 April 2013 (UTC)[reply]

Peer Review for Education Program:Boston College/Developmental Biology (Spring 2013)

I made some quick edits to spelling a grammar mistakes that I was able to pick up on. The introduction and history sections were perfect. There is a ton of information on this page and seems to be well organized to me. The order and the headings all seem well placed. There was a good flow to this article. It is really difficult to follow the movements of the cells and the changes that the embryo undergoes based on how it is described. It is obviously difficult to explain all the different moving parts in words. Maybe you guys could find a picture that illustrates what is happening better, especially for the parts about gastrulation and neurulation. All your citations seem ok to me and there are definitely enough wikilinks.

Hope this was helpful Aadharm (talk) 01:08, 12 April 2013 (UTC)[reply]

I didn't pick up on any spelling/grammar mistakes so good job to you and the first reviewer. I feel that the introduction is easy to comprehend even if read by someone without a biology background. One comment that I would make on the first paragraph would be that in the third sentence you say "forms from the outer layer" maybe replace that with "originates from". The article has a good flow and does a good job describing the complicated movements taking place. However, I agree with the other editor that pictures would be useful for future readers to visualize the process such as gastrulation and the hinge cells that you discuss. Some of the links you had to other pages(the hinge cells and bottle cells) don't work, and I'm not sure if you need to repeatedly link the same terms throughout. Also, not sure why selective affinity is in bold on the page. One final comment I have would be to add another sentence or two to the organogenesis just to flesh it out a bit more.

Great work so far keep it up. Pleusm (talk) 23:33, 13 April 2013 (UTC)[reply]

As Aadharm mentioned, the organization of the article is great in its current format. I think that the introduction does a good job of outlining the basics regarding ectoderm and ectoderm differentiation. Whether it is in the introduction or in the actual ectoderm differentiation section, it might be helpful to include a flowchart-like table to outline the process a bit more specifically. While the information you include in the page is great, I think that organizing some of the more important steps in a viewer-friendly table would help improve the page even more; unfortunately, I feel as though large uninterrupted blocks of text can be daunting for the average reader (someone who isn't reading it specifically for class as we are) and a chart may be a nice supplement to keep such a reader engaged.

Along the same lines, it may also be a nice supplement to add a few more images to the Differentiation section. Even if they were just a few pictures depicting animal/vegetal poles of a cell or melanocytes, I feel as though figures are refreshing as they give readers a visual example of what you are explaining in such detail. For example, in the associated disease section, you could include a picture of a patient displaying the symptoms of ectodermal dysplasia. It's just a thought and could be a nice addition to your article.

The Gastrulation section is written very well for the Wikipedia community in my opinion. As professor Hake mentioned in class, most people reading these pages will not be enrolled in Developmental Biology and, as a result, will not be quite as familiar with some terms as we are from preparing for exams, quizzes, etc. In this way, I think that you did a great job including additional explanations in the Gastrulation section to clarify certain terminology. While it may be difficult, I think it would be worth while to try something similar in the Neurulation section because it seems to be a bit denser in terms of biology language in my opinion.

In addition, the organogenesis could perhaps use a little bit more information—I'm not sure if you were already planning to add more to this section, but I just feel as though it is a bit of an abrupt ending to that section of your article. All of the information you included beforehand is so in-depth and well-explained that it leaves you with a bit of a tall order as far as a closing. The information in the organogenesis section is definitely good—I simply feel there could be a little bit more. On the same token, I always find related diseases to be among the most interesting things to read about when it comes to science Wikipedia article so I think it was a great portion to close with. If there are other related diseases besides ectodermal dysplasia (even if it is not extremely closely tied), it might be nice to include some information and maybe an image.

Overall, I think that you did a wonderful job with the article. It was interesting to read and, while I did not read the original page, I am sure that your work has taken the article to a new level. I hope that you find some of my suggestions helpful—you really did some nice work and made my job as an editor much easier. Great job! TheRealTPng (talk) 23:36, 13 April 2013 (UTC)[reply]
