Edit Summary
Working from the top of the article down, I started with the lead section. I reworded and lengthened it while adding a brief summary on the function and diabetic pathogenesis of beta cells. I also corrected a statistic regarding mice to a more relevant human statistic and found a citation for it.

Moving to the function section, I created insulin synthesis and secretion subheadings for clarity and to emphasize the two main roles of the cells. I moved the first paragraph that was in function above these two subheadings, as it acted alone as a good introduction to overall function. I also added a whole paragraph to insulin release as an intro/overview before entering into more detail. I fixed various typos and added a few extra facts along with 7 new citations. This was initially a very under cited section. Moving on to insulin production, I added this whole section and citations since it is a very important function independent of secretion. I think it helped to highlight some beta-cell organelles also. Next I added a diagram of the secretion mechanism as a visual way to understand it. I included proper attributes and copyright info.

Next, in the clinical section I made T1D, T2D, insulinoma, and medications subsections for better organization and to add more info on how each relates to the beta cell. I moved a paragraph from the research section defining T1D to the clinical section since it seemed misplaced and redundant. I then found and added 3 citations to it since there were none, although the information was correct. In the T2D section I deleted an incorrect fact about sugar consumption causing diabetes, edited the current info to read better, and added some pathogenesis as it related to the beta cell. Next I researched and added a citation to the existing insulinoma section. Finally in this clinical section, I added a medications subsection since some diabetes medications act directly on the beta cell along with a couple citations.

In the research section, I started by moving a sentence about experimental induction of diabetes from the clinical to research section since the chemicals are used in mice. I also deleted an opinion based sentence that stated the best way to treat T1D is through stem cell therapy and removed another unreputable citation with its associated sentence. The whole T1D research section had no citations so I found a few and added them, verified the sentences were true, and then removed the "unreferenced maintenance template" box that was added by another wiki member previously. Then I added an experimental techniques section to go over some common ways data is collected from beta cells. Finally in this section, I added a T2D section reviewing some of the most researched topics in the field accompanied by 4 citations.

Cleaning up at the end I added "Islets of Langerhans" to the "see also" section. I then went through and added some in-text word links to other wikipedia articles. In total, I added 22 new references and had to re-edit some that had incorrectly formatted dates.

Beta Cell- Part of mol/cell bio and anatomy wiki projects. Start class, high importance.

Article Evaluation
Lead section- Could definitely be improved. Way too brief and does not even say that their job is to secrete insulin. Could also mention what goes wrong with them in type I and type II diabetes.

Structure- Would like to add more sections. Maybe a history section describing when they were found and any big discoveries about them. Add a section about type II diabetes in the research heading. Create subheadings under clinical significance about type I and type II diabetes since I plan to expand upon this info.

Balanced coverage- Whoever edited the research section only researched type I diabetes so type II needs a section. Other than that, functions and other biological info about the secretion pathway need to mention only the fields overall consensus.

Reliable sources- many more citations need to be found, specifically in the function section since everything here needs to be cited, and the research section which has many uncited claims about type I diabetes. Clinical data would be helpful in the clinical significance section also.

Initial evaluation:

Could add a history section, section on beta cell failure/pathogenesis, more citations in the function section, add figure(s) regarding the insulin excitation-secretion pathway, expand on clinical significance, remove or move experimental induction of diabetes to research section, find as many citations as possible for type I diabetes research section and create type II research heading.
