Cell Therapies - (Sep/11/2012 )

In the 1950's Swiss Dr. Paul Niehans transfered live animal cells ( sheep and cows ) into human's with claims of achieving successful human rejuvination . Is such a medical concept feasible ? Can animal cells with a different DNA initially live within a human and secondly can such cells migrate to function in human organs ? Your assistance in this matter would be appreciated .

Your immune system would recognise these cells as foreign and destroy them.

The cells can live for a while, in theory this should work, but as Leelee says, the immune system is a problem. However, there are a fair number of people around with cow or pig or perhaps sheep heart valves, and you should look up the ears and other structres that have been grown on nude mice.
