>>Anything past those two are wishful thoughts. hardly just skin and liver! It is easy to find information about e.g. therapies for horses' joints. This link is about humans, just a few years from patients. http://news.bbc.co.uk/2/hi/health/1809322.stm http://news.bbc.co.uk/2/hi/health/1809322.stm There are people walking around with bladders and (built with a scaffold) throats. There are grown muscle patches for hearts, etc. (I didn't mean to replace parts of the brain surgically of course, stem cells rebuild damaged areas after strokes.) (I assume you aren't claiming that Parkinson won't be cured in 20 years?) Do you have any references? What are the show stoppers to scale to more complex tissue? The field obviously moves fast. Muscles like the heart and "simple" organs like kidneys should probably be possible. Is blood supply not solvable? Edit: Sorry for coming back a few hours later. (I was downvoted a while? :-) )
