i did not know this was under development!! praises be to the higher powers
there was a tv news story about an artificial kidney here in the denver metro area not too long ago. i don't know if it's the same doc, but it said the kidney had been functioning appropriately in the lab for quite some time. the problem is figuring how to make it small enough to make it implantable. there may be hope yet.
Even though practical application of this technology could be 10+ years off the fact that it is being actively worked on, along with other solutions (eg: stem cells, the "wearable" artifical kidney, the diamond based implantable filters, etc) means that there is hope, maybe not for our generation (but maybe for it too!!) but that future folks will not have to suffer through dialysis, or horrid anti-rejection drugs and all the rest of it.
