Posting a Diary Entry

Daily Kos welcomes blog articles from readers, known as diaries. The Intro section to a diary should be about three paragraphs long, and is required. The body section is optional, as is the poll, which can have 1 to 15 choices. Descriptive tags are also required to help others find your diary by subject; please don't use "cute" tags.

When you're ready, scroll down below the tags and click Save & Preview. You can edit your diary after it's published by clicking Edit Diary. Polls cannot be edited once they are published.

If this is your first time creating a Diary since the Ajax upgrade, before you enter any text below, please press Ctrl-F5 and then hold down the Shift Key and press your browser's Reload button to refresh its cache with the new script files.

ATTENTION: READ THE RULES.

  1. One diary daily maximum.
  2. Substantive diaries only. If you don't have at least three solid, original paragraphs, you should probably post a comment in an Open Thread.
  3. No repetitive diaries. Take a moment to ensure your topic hasn't been blogged (you can search for Stories and Diaries that already cover this topic), though fresh original analysis is always welcome.
  4. Use the "Body" textbox if your diary entry is longer than three paragraphs.
  5. Any images in your posts must be hosted by an approved image hosting service (one of: imageshack.us, photobucket.com, flickr.com, smugmug.com, allyoucanupload.com, picturetrail.com, mac.com, webshots.com, editgrid.com).
  6. Copying and pasting entire copyrighted works is prohibited. If you do quote something, keep it brief, always provide a link to the original source, and use the <blockquote> tags to clearly identify the quoted material. Violating this rule is grounds for immediate banning.
  7. Be civil. Do not "call out" other users by name in diary titles. Do not use profanity in diary titles. Don't write diaries whose main purpose is to deliberately inflame.

Please begin with an informative title:

Regenerative medicine is coming and when it does it could transform medical care more dramatically than the development of antibiotics to treat infections and blood transfusions to save trauma patients combined. Here's how it might work:
IN PRINCIPLE, THE PROCESS of treating diseases with stem cells made with a patient’s DNA will work something like this: 1) take easily available cells (like skin cells) from a patient with, say, Parkinson’s Disease, 2) transform the skin cells into stem cells, and then 3) coax those stem cells to become dopamine-secreting cells, which you can transplant back into the patient. If you’re really ambitious, you can edit the DNA of those cells to repair the Parkinson’s-causing mutation before transplanting them back into the patient. A second approach is to 1) take isolated DNA from a patient, 2) transplant that DNA into a donated human egg cell, 3) induce that egg cell to become an embryo and extract the stem cells, then 4) use those stem cells to create specialized cells that get transplanted back into the patient.
We would probably need to tweak existing laws for something like that to become a reality. Fear of the sci-fi clones could hamper some research. But most importantly, to get adult stem cells to do what embryonic stem cells do, we first have to understand at the very least precisely how embryonic stem cells work. Which involves ... studying embryonic stem cells in great detail. Duh.
