Whole Organ Grown In Animal For First Time
An anonymous reader writes British scientists have produced the first working organ grown from scratch in a living animal. Reprogrammed cells created in a lab were used in a mouse to produce a thymus. The organ was created using connective tissue cells from a mouse embryo and were converted into a different cell strain by changing a genetic switch in their DNA. The resulting cells grew into the whole organ after being injected. It has only been tested on mice so far, but researchers at Edinburgh University say that within a decade the procedure could be effective and safe enough for humans. The findings were published in Nature Cell Biology.
Maybe not.
One could grow organs inside a person's body or in a tube, but there are issues about blood supply, proper growth, etc. A possible solution would be to grow human organs in animal hosts. Transgenic pigs are often cited as a possible choice. They are about the right size for many organs and their immune system should be able to be tweaked so as not to reject the foreign tissue. Of course, this approach has other technical hurdles to overcome. I am not willing to bet on what the answer will be.
Still in the realm of science fiction but we are getting closer every day.
