China Internet TV: [The world's first "customized baby" was born] "Want a blond baby girl? We can do it" A Los Angeles clinic said it provides services for selecting the baby's gender and physical characteristics. Recently, the world's first genetic screening test-tube baby was born in the United States, which means that genetic screening techniques that "select the best genes from parents' genes and cultivate the desired baby" will become more popular. Artificial perfection or natural selection, where will humanity go?
Recently the world’s first genetic screening test-tube baby was born in the United States, which means “from parents The genetic screening technique of selecting the best gene among genes and cultivating the desired baby" will become more popular. Artificial perfection or natural selection, where will humanity go?
Customized babies refer to the use of "pre-implantation genetic diagnosis" to form embryos with "in vitro conception", then test the genes of the embryos, and then choose not to have specific genes Embryos (such as cancer) are implanted into mothers and eventually develop into babies. Scientists who have successfully bred "custom babies" say that this technology is to help humans conquer the diseases hidden deep in the characteristics of life, and use purer genes as the key to open the happy future of mankind.
The first British baby who was genetically screened to avoid hereditary breast cancer was born in London on January 9, 2009. The British media called her "cancer-free Baby". The British media quoted the mother of the baby as saying that all women in the three generations of the father's family had breast cancer, and the earliest illness was only 27 years old. She and her husband decided in June 2008 to take action to protect their offspring from breast cancer.
This test method is called "pre-implantation genetic diagnosis". It usually uses "in vitro conception" to form an embryo, then tests the embryo's genes, and then selects embryos that do not have a specific gene (such as cancer) to implant into the mother. The University College London Hospital tested 11 embryos for the couple in 2008 and confirmed that 5 of them did not contain the BRCA1 gene that can cause breast cancer.
The doctor implanted two of them into the child’s mother’s womb, and finally one developed into a baby. Society generally has sympathy for such families with family genetic history, because members of these families live in fear of some kind of cancer at any time. In this context, the British Human Fertilization and Embryo Administration, after conducting a public consultation, decided to allow the use of PGD technology to screen breast cancer genes.
Thus, this customized anti-cancer baby girl was born and also ended the family's genetic history of breast cancer. More importantly, scientists and doctors at the University of London School of Medicine have also been approved to use PGD technology to detect whether embryos contain other genes that are likely to cause malignant diseases, including bowel cancer and retinoblastoma.
The young parents who customized the anti-cancer baby girl (they are only in their 30s) are very happy, because their daughter will not inherit the BRCA1 gene and may die in a young age, and no one will encounter it in the family in the future This doom. Scientists and doctors are also very happy because they have achieved success in the cutting-edge technology field of genetic engineering, making it possible for humans to eliminate genetic diseases.
