British doctor who first engaged in the cultivation of children in test tubes, predicts that stem cell technology make it possible to grow spare parts for virtually any part of the human body.
According to 82 - Robert Edwards summer, a new branch of regenerative medicine will allow patients to use their own cells to grow heart, liver and kidneys with their own blood to replace sick bodies.
These achievements can rid of the need for transplant operations and make possible regeneration of brain tissue and limbs.
Already conducted research to understand how some lizards grow tails and some types of mice, rabbits and deer restored.
“We know that for the human genes its possible, as it happens to the human embryo - said Edwards. - If the term of pregnancy up to three months an embryo losses finger, it grows the new one. There are genes, but we need to understand how use them”.
In 1978, a cell biologist Edwards and his colleague Patrick Stepto first time in the world created an embryo with the help of extracorporal fertilization (IVF).
The child, Louise Brown, which in July will turn 30 years old, now a married woman.
Her son, conceived naturally, is already 18 months. She became a pioneer of worldwide industry, through which a lot of infertile families bear 1.5 million children.
Some scientists hope to learn how to grow replacement organs in the human body and exploring the ability of such animals as the salamander, produce blastema in adult and able “grow” new limbs and tails.
When activated from the human genome, this ability may allow the bodies to recover from injuries much deeper than is possible naturally, up to surgical amputation. After the restoration there is no scars.
Some experts believe that one day it will be possible to use such technology for the continuation of life by rejuvenating aged body parts. Julia Polak, an honorary professor of tissue engineering and regenerative medicine at Imperial College London, argues that the tests “spare parts” for the human body is already under way.
They will be used for the first time just in a few years to treat paralysis and blindness.
