Custom Grown Organ Tranplanted!!!!

In what is the first example of what will, no doubt, ultimately become the standard procedure in organ transplantation, a woman has received a whole organ grown from her own cells! The benefits of this are many. No more organ shortages. Even better, no anti-rejection medications! Since the organ is grown from your own cells, your body doesn't reject it.

If you follow the link and read the whole article, you'll see that right now they can only do "hollow' organs like the esophagus, but they hope to be able to expand that and, one day, custom make any organ.

 

I think this is amazing and we may live long enough to see the time when organs will be grown as needed.

First a black president, now organ farms. When do we get the flying cars?

Never.

I heard bladders are being made as well.

 

Bladders were being made years ago, this certainly is a next step but complex organs like the heart, kidneys, lungs, etc are still a breakthrough or two away.

Also embryonic stem cell research is still valid and critical to this field.

 

Guess what?!

 

I quoting that.

 

Replacement organs grown in vitro with patient-matched cells are a dream of modern medicine and science, and it looks like we’re almost there (to a limited degree). Earlier in the year there were the reports of tissue engineers growing new beating hearts (in rats only at this stage), although that research is not yet at the stage where they can be transplanted.

One thing to bear in mind is that, although they are amazing pieces of tissue, a trachea is just a tube, a heart is just a pump and a bladder is just a bag. These “simple” organs were always going to be the first organs that could be tissue engineered and transplanted. There is a world of difference when we move onto “complex” organs like the liver and kidneys. The liver is both an endocrine and exocrine organ containing an incredibly complex array of many different cell types doing a variety of different physiological functions. It is the major detoxifying organ of the body and produces a huge array of different hormones and compounds. I cannot see anyone being able to tissue engineer a liver any time soon. Likewise with the kidneys.

 

HR, i actually posted a thread on this a week ago. The bladder has already been done, i dont know the exact dates to see which one came first this women or the other one but i do know they grew her a whole bladder and transplanted it.

as you posted they are already growing hearts and experimenting with other organs. However i would have thought the ovious one this would work on is the liver because that will regrow itself naturally. Hence you can have a live donor liver transplant where they just cut yours in half and leave one half in you and stich the other half into the pt

 

Yes, the liver has an amazing regenerative capability. But that procedure suffers from the same problem that all traditional transplant procedures suffer from – the need for a compatible donor and the necessity for the recipient to take immunosuppressant medication for the rest of their life. Many people die on waiting lists for compatible donor organs.

The aim of tissue engineering is to grow necessary organs using patient-matched cells. This removes problem of immune rejection. However, as I said above, to grow a new liver using a patient’s cells is not going to be easy. Tissue engineered hearts will be accomplished long before it is accomplished with livers and kidneys.

 

oh on a side issue, did you hear of the resurchers who have managed to "wash" blood so that it is ALL O- there for eliminating the requirement to cross match before tranfusion or to relie on dwindiling stores of O- blood.

I belive the resurch was done for the millarty because they have the biggest trauma rates but the whole health system could benift

 

Do you have a link? It sounds very interesting.

ops, i was wrong, they cant convert pos to neg so it would be all either O pos or O neg

 

It simple just strip the markers of the blood cells, make any type into universal O-

 

how simple? Can it be done in a MASH unit?

 

you asked for the link, follow it up

 

Wow

, still pretty useful, though.
