[NYTimes] Setback for New Stem Cell Treatment

post #1 of 17
Thread Starter 
Quote:
In an unexpected setback to efforts to harness a promising new type of stem cell to treat diseases, researchers reported on Friday that tissues made from those stem cells might be rejected by a patient’s immune system — even though the tissues would be derived from the same patient.

The research involved so-called induced pluripotent stem cells, or iPS cells, which can be made from skin cells and which appear to have the characteristics of embryonic stem cells. That means they can theoretically be turned into nerve, heart, liver or other types of cells and transplanted to repair damaged organs.

I've learned so much about iPS's through the research lab that I'm in, and it's kind of disheartening to find out that tissues created by iPS's are rejected. I really hope that there's some way to overcome the deficiencies that apparently inherent in using iPS's vs embryonic stem cells so that we can have treatments for hard-to-cure diseases in the near future

Well it says 'might be rejected' so wouldn't that mean there is some margin of success at least?

Don't get too down, wouldn't be surprised if there were numerous factors causing some rejection, maybe even tissue growth techniques/culture residue etc. Don't forget even on identitical twins, the chance of rejection is very low, but still a chance.

OR maybe instead of people letting themselves go, being sedentary, eating horrible ****...etc etc and then looking for band-aids for our poor health decisions...
We should invest and rely on ourselves for good health, instead of drugs.

Yes, because that's what stem cells are for. Nobody would ever need a new organ or tissue because of something like a car accident, fire, crazy person with a gun, etc.

The person who can engineer cells (or change them) that aren't rejected by a host's body will be in the record books forever.

Edit: Self-censored. People are right, this isn't the place, I just had strong feelings on the matter.

The solution is simple. Use embryonic cells.

Why is it so hard to harvest babies for this kinda thing. Lots of creatures in the animal kingdom eats their own young... They must know something we don't!
