That has interesting implications. Imagine a kidney grown from the person's own tissue. There would be no problems with rejection. The kidney is a complex organ with many microtubules and blood vessels. It would take more than laying down a few cells to formulate a functioning kidney. Still the implications are vast. To be able to do a heart bypass operation with a new vessel created for the purpose, rather than having to take veins from the legs as is now the practice. Less surgery and it would be the right kind of vessel from the start. Maybe they will be able to form spare parts for those who have lost limbs or vital organs. Maybe even pancreases for diabetics. The mind boggles at the vision.

If you don't care for reality, just wait a while; another will be along shortly. --A Rose
