Womb, gene therapy

Many people or families know and have suffered in flesh and blood the devastating effects of a genetic illness that affects severely anyone of their newborns without previous warning. Illnesses like Hemophilia, Syndrome of Down, Cystic fibrosis, Sickle cell anemia and many metabolic illnesses that attack fetuses with permanent (for a lifetime) defects, having the therapy -mostly- palliative effects, as long as the damage (as in most of the cases) already has been done. The future could change in about 5 years, if the experiments of genetic therapy (substitution -in uterus- of abnormal genes, for other normal ones driven to the fetal cells by carrier virus), are effective in human. The therapy has been successful in fetuses of hemophilic mice where the illness was reverted ad integrum. Now, British scientists get ready to carry out the same experiment in animals but big : fetuses of sheep and primates, for finally to be carried out in human. According to Simón Waddington (College London) and Charles Coutelle (Imperial College), 2 obstacles conspire against a genetic successful therapy: 1) the immune rejection mounted by the host body to the implanted genes, fact that one waits to overcome working with fetuses where the immune answer is weak and 2) the development in some fetuses (years but late), of cancer, effect that is hoped to revert with carefully planned and watched studies.
