Also called “double hope baby” or “baby-doctor”, the infant will cure his siblings with genetic disease. Explanations.

His name is Umut Talha, which means “our hope” in Turkish. A baby of three kilos and 650 grams, healthy, born January 26 Antoine hospital and innocently revolutionized French medicine. Doctors rely on its umbilical cord stem cells to treat it contains his elders. Back on a new medical practice ethically complex.

Who is the designer baby?

Find a compatible donor sickness is often the obstacle course. Especially when children of the same family, genetically closest and therefore most likely to provide biological tissues are affected by the same disease. A hopeless problem which must address the designer baby . The double hope baby is so named because, in addition to being sick, he can save his brothers and sisters. For this, an embryo obtained by in vitro fertilization (IVF) is subject to a double preimplantation diagnosis :

* First check ensures, as in a conventional preimplantation genetic diagnosis, the embryo is not affected by the disease that eats already the family;


* The second, and this is the novelty, offers the possibility to check the compatibility immune – required for any transplant – between the unborn child and his brothers and / or sisters who are sick.
Once these genetic analyzes performed, the embryo is re implanted in the uterus. At delivery, the umbilical cord is rich in stem cells, is collected for said cells can be subsequently grafted with one or more children sick family. Unless placenta are collected or subsequently bone marrow donor.

Babies, doctors, reflection and long medical approach ,

Authorized since August 6, 2004, this approach has strictly controlled the first baby born drug-more than 6 years after In vitriol fertilization is in itself a long ordeal Medical, which is accompanied by an ethical agency entrusted to bio medicine. The latter decides case by case the possibility for a family to give birth to a baby-doctor.

Two criteria are required a priori. First, the illness that affected children is incurable and causes early death, like beta-Tallahassee hitting seniors breakfast. Then, the graft must make a potentially significant improvement in the health status of the child recipient. The procedure can not engage unless written consent and necessarily reiterated was issued by the parents. Babies are born drug in recent years elsewhere in the world. Including the United States since the late 90s. Two births of this kind took place in Belgium in 2005 and in Spain in 2008. Few births, which in France as elsewhere, raises ethical questions.

Babies drug and ethics

Double hope baby raise a double ethical problem. Firstly, there are the questions about the place of designer baby in the family. Relationships between parents of the child savior will they be identical to those uniting sick children? What is the link between sibling-ill toddler medicine? Second, the questions raised are those inherent to transplantation in which donor and recipient are not anonymous, even meet each other. Two situations can arise. If successful, what will the debt burden of the saved person to his benefactor? In case of failure, what is the burden of guilt for the cherub in which all hopes were placed? Some even suggest the possible eugenic inseparable reimplementation genetic analyzes. Medical advances, particularly in the field of stem cells and for gene therapy leave much hope for families affected by genetic plagues. Aspirations necessarily accompanied by ethical issues, to avoid abuses.
