In this article, super-resolution microscopy was used to localize and focus (right red points) on more minute details. Whereas, normal microscopy is only limited to a few hundred nms magnification (left red point). Super-resolution microscopy can focus to the point of or less than 100nm, which is useful when researching into the structures of a cell.

1. Do you see a difference in phenotype between Tm4 over-expression and control cells?
Tm4 consists a majority of stumped and pronged phenotypes, whereas, broken fans and fans are more common in the control samples.
2. If so, how could Tm4 over-expression lead to this difference?
The increased number of stumped and pronged phenotypes present in the Tm4 sample suggests that Tropomyosin 4 over-expresses in phenotypes that has more branching processes, thus more interaction between phenotypes.
Part 2 - cAMP
- More processes and branching [more interaction]
- Lighter periphery staining
- the major phenotypes are stumped and pronged
- Less Branching [less interaction]
- Lighter periphery staining
- consists of more broken fan phenotypes

- Brief, but detailed insight into Testosterone Signalling
- The table layout is great and well referenced, however, the colour might not be too appropriate
Biosynthesis & Regulation
- I thought these two parts were easy to follow, although biosynthesis was a bit hard to understand. Probably could have included a bit about the Bolded words.
- I thought this section was nicely structured. It flows, with relevant images and introduces the classical and non classical pathways which ties nicely to the next section.
Normal & Abnormal Function
- The section for Normal function could have added some sub titles so the readers won't feel too overwhelmed with the extensive texts, but it was informative. The abnormal function provided interesting introduction into the different outcomes.
Clinical uses & Current Research
- Provides an informative and insightful understanding as to how this relates to the bigger picture. I thought it was a good conclusion to the project.
- Maybe a bit more info would be good, slightly brief
- Good use of table, well referenced and the colour choice was good, not too bright.
Normal & Abnormal Function
- I thought normal function should come just before abnormal function so readers could have a better comparison between the two, and the signalling pathway could be better placed just after the introduction. The table in abnormal function was great, with the relevant images placed, was really helpful.
- I thought that maybe the information in this section was a brief, could use a bit more information. Also, it would be nice if there were some info under VEGF, so it won't seem like theres nothing done on it.
- The information was well researched, but the layout wasn't as clear. Maybe the pictures should all go on one side of the page, to present a clearer page.
- Better placed before the Reference, as readers might miss it.
--Mark Hill 13:34, 17 May 2012 (EST) You have not completed the peer assessment process yet. If you have made comments on each project page they need also to be pasted here today for me to include in your individual assessment.
- could be a bit more brief, just list the components that will be discussed.
- good information however, reference needed
- could do with a bit more info and pictures would help with explaining how it works
- The information flows but not much structure. Sub headings would help give a clearer understanding. Abnormal function?
- Again, headings would give readers a better understanding of what they are reading, but good articles and examples
Glossary and References could do with some work
- Clear cut and straight to the point
- a bit too brief
Pathway, Proteins and Receptors
- I thought the pathway was well explained, but more detailed description would be better. Also, proteins and receptors might be better as a subheading under pathways? The image is good, but maybe should include a brief description
- This section is well researched, clear layout and the flow chart helped in explaining about the role of Notch in CNS. Each sub section has a nice intro and, brief detailing and closing, overall i thought this section was good.
- Lack of description on each article, even a brief intro on what they are researching on would be good
- A great introduction to the topic, it incorporates the information that would be discussed
- I thought it was really good as it is well referenced with links to abbreviations
Mechanisms of action
- Even though it was in point form, it was clear in explaining what it does and how. I thought it was refreshing as it is a bit different from others, and doesn't seem like information overload. Relevant image with description, easy to understand.
- Good use of table and images to present the different type of disease. Good amount of information on each disease, brief but informative
- again, table gives a nice layout, and information given shows extensive research done
Overall, i quite like the layout and the amount of effort put into this page, as it shows enough information but not too much, and glossary links and the list of terminology provide an easy read. Well referenced.
- Intro should be brief and the pathway discussed should have a separate heading. I liked the drawing, its easy to process and follow, although the references were a bit confusing, would be better if it was in text citation.
- Well written and referenced
Gene Description & Receptor Agonists
- Lacking a bit of reference, Betas 1,2& 3 could use a bit more info. The table for Receptor Agonists is too bright but table layout is good.
- Very detailed section, with relevant images,
Pathway & Normal function
- good image albeit a bit confusing with lots of arrows but i understand its the pathway thats hard to grasp and not the picture Great job. This section is well written and well explained.
- great use of table - information easy to absorb. Very well researched and interesting topics on SCD and DCM
- Sufficient info on each term to provide a good understanding to the overall topic
- Brief but introduces the topics that will be discussed nicely
- The process runs nicely with the image, however, more information would show a bit more depth in the understanding of the topic
Normal Function & Abnormal Function
- Block of information, probably could use lists in some cases, (new line for 1, 2, 3, as it gives a bit more structure and won't seem to boring) Needs referencing, and some images would also help.
- Maybe a table would help?
- Again, lots of good information, but its all in a block. Readers might get bored with tons of info, so structuring it out a bit would help, also adding images could lighten up the page
Need some info on current research, but overall theres a lot of info, just need to do some work on structuring
- Good intro, could end with what you'll be discussing throughout the page
- sub headings for the different pathways and then more information on each. More referencing needed
- well researched and referenced, although i think History should come just after introduction, so its like a background to what is being researched.
- needs more work, and best placed at the end, just before glossary, a good wrap up
- Well researched, but a bit more info under each heading to show more knowledge on the topic
- lack of information, and should talk more about the progression to carcinoma
- well done

- Gene expression profiling was performed in different studies using human Mesenchymal stromal Cells
- cRNA was synthesized from total RNA and transcribed
- Fragmented cRNA was then hybridized to GeneChips
- GeneChips were then washed, stained and scanned with GeneArray scanner
- Raw Gene data were then processed for signal calculation
