replies: text:  Definitely in favour of a total merge. Not sure how you could create the article suggested above - nice idea but I just can't work it out - surely one general article on skin is enough for wikipedia with the separate pages that already exist containing more detailed biological information Madmedea 17:00, 2 January 2007 (UTC)

text: Regarding the proposed merge, the epidermis is just *part* of the skin. -- Schneelocke 12:56, 17 February 2007 (UTC)

text: No to the merger. As stated above the apidermis is one part of the skin, and all parts need an article. We have lots of articles on dermatology. Whether our articles are currently too human-specfic is another issue. I don't see that contracting the skin articles will be of benefit regardless Secretlondon 00:00, 7 March 2007 (UTC)

Apparently, someone has been working on this article who isn't very familiar with English. I can tell because parts of it sound like crap.  —Preceding unsigned comment added by 63.245.164.72 (talk) 07:28, 5 May 2008 (UTC)

thread_title:  Number of layers 

message: Perhaps I am ignorant of the way things are referred to in biology, but I think that the description is somewhat confusing. 
It states: 
This inner layer is a germinal epithelium that give rise to all epidermal cells. It divides to form the outer spinous layer (stratum spinosum). The cells of these two layers, together called the Malpighian layer(s) after Marcello Malpighi, divide to form the superficial granular layer (Stratum granulosum) of the epidermis. [9]
So when the germinal epithelium "divides" to form the stratum spinosum, does it continue to be the germinal epithelium too?  The word "divides" implies more than one thing produced. 
The product of division is then referred to as "the cells of these *two* layers. What are those two  layers?  
The "two layers"  "divide" (again) to form the stratum granulosum.  Again, what is the other side of the division.
In the end, according to the picture of the different layers of the epidermis, there should be a basale, spinosum, and granulosum stratum.  Would it be clearer to say that :
the germinal epithelium divides to form the basale and spinosum strati, and the spinosum further separates and differentiates to produce the stratum granulosum.
It is also not completely clear to me how this section relates to the section Cellular Kinetics.   That section states that cells form at the stratum basale, take two weeks to reach the stratum granulosum, and then a further 4 weeks to reach the outler layers of the stratum corneum.   However, in this section, it seems to imply that keratinocytes are formed in the stratum granulosum, not the stratum basale.   Perhaps a diagram showing the names, origins, and dynamics of the different cells would help.  —Preceding unsigned comment added by 131.215.220.164 (talk) 04:18, 22 March 2011 (UTC)
thread_title:  Organogensis section is not clear 

message: Keratinocytes produce keratin. This keratin accumulates in the epidermis but is it intracellular keratin or extracellular? I think it is intracellular but the article states this:
"Differentiated keratinocytes secrete keratin proteins which contribute to the formation of an extracellular matrix". --Miguelferig (talk) 19:55, 8 August 2012 (UTC)
