    Hey Jonathan,
    I really enjoyed your post and found your tittle very intriguing.I have a few suggestions:
    – In your first paragraph the wording of “gaining steam” is a little weird you may want to consider changing this
    -label your figure- figure 1
    -In you fourth paragraph your two last sentences are very long, you may want to consider shortening these to increase clarity and flow
    – last paragraph- i think you can omit ” printing of organisms”

    Hi Johnathan,
    Great post, I thought that you compared and contrasted each technique in a way that made it very easy for the readers to understand.
    In the fourth paragraph, you should change it to“an identical replica”.
    As well, you should change “of” to “on” in “focuses instead on manipulating”.
    I found the figure a little to small, and couldn’t read the labels on the image. If you could make it a little bigger that would be great.
    Good luck with your editing!

    Hi Jonathan,

    My housemate was telling me about this the other day. It is super cool! Your blogpost was very well written. Most of your sources are also recent, and all pass the CRAAP test. I think you did a great job!

    Hullo Mr. Ho,

    Have you looked into self-assembly that is directed by external mechanical forces? I was reading about tissue engineering that used parallel plates with undifferentiated cells between them, then moved the parallel plates towards and away from each other, like a pair of lungs. These cells then differentiated into lung cells. There was some cool research that pointed to stretch receptors in the cells as the source of this phenomenon, and they showed that those stretch receptors could directly cause cell differentiation change gene expression. That’s the limit of my knowledge on this subject; I thought you might be interested.

    I have one question: how do cells survive being printed? You mentioned this as an additional layer of complexity, and I think a small expansion on this topic would be interesting.

    Hi Jonathan,

    First and foremost I must say you have a very effective title for your piece. It immediately drew me in to read the piece. Overall, I think your post is very well written and well developed; you explained each of your concepts in a thorough and detailed manner making it easy to see the pros and cons of each method. Moreover, you have a good set of literature to back up your information. I do have some general comments about the post:

    1. Your last sentence is rather long-winded and a tad confusing. It may be beneficial to break this sentence into two separate ones.
    2. The wording of your second sentence in the introductory paragraph sounds a bit odd as create and creative are stated in close proximity to each other. Perhaps consider changing “create” to “generate” or “produce” to make the sentence flow a bit better.

    Overall, you did an excellent job both in content and writing! Good job!

    Good luck,

    Julia Pantaleo

    Hey Joho,

    Wow! Nice blog topic and great writing style/format for your blog – …I can tell you are taking english this semester! Here are a few comments for improvement:
    – I particularly liked the image that you included – although I think you could use it more effectively. Either make your figure caption more detailed or include more of the specifics of the process in your text for each type of tissue modelling!
    – I also would like to have seen more information on the progress made with bioprinting and the exciting recent medical discoveries that have been made with this modelling. What organs are they able to print with success and what have they been able to accomplish with the printed biomaterial?
    – I agree with Jamie that the fourth paragraph needs to be divided into more concise sentences.

    Thanks for the read and happy editing!

    Nikki 🙂

    Hi Joho,

    Wow this is such a cool topic. I had no idea that they could print entire organs. I had read in the past about using pluripotent stems cells and using certain signalling molecules to induce their differentiation to make certain tissues, but never about printing an entire organ. Here are some minor suggestions:

    1) The end of one of your sentences in your first paragraph was a little confusing. I wasn’t sure what you meant when you stated “without requiring skills in the manufacturing process”.

    2) In your bracket “(ie. The nephron of a kidney”, the “ie.” should be “i.e.”

    3) You mention in your conclusion the benefits and drawbacks of each technique. This might be worth expanding on as an additional sentence per sub-topic. As a reader, I was not too sure what the benefits or the drawbacks of each technique were. You could also just delete that statement, so the reader isn’t left wondering.

    Thanks for the read, it was really cool!

    Happy Editing,

    Hey Joho!

    I like your post and it was very well written. There was just one thing that left me wondering when I was done reading it. Are these three methods used for printing different organs? Which scenario are each of them used in? Or does each one better than the last?

    Happy editing!

    Hi Jonathan,

    Interesting topic! This application of 3D printing is pretty useful. My only comment is that you have a slight overuse of commas: take a quick look at them and see if they really are necessary.
