The researchers said results will help them understand how a healthy human embryo develops, and “this knowledge may improve embryo development after in vitro fertilisation (IVF) and might provide better clinical treatments for infertility“.

Just weeks after Chinese scientists induced internet tumult by saying had genetically aligned human embryos, Kathy Niakan, a arise cubicle inventor from London’s Francis Crick Institute, has inquired the British government’s conception valve and get a freedom to enact comparable study.
The Human Fertilization and Embryology Authority (HFEA) confirmed that it had received an application to use the CRISPR-Cas9 gene-editing technique in a licensed research project, and said that the request would be considered in due time. Her team would be using the CRISPR/Cas9 system, a proven effective technology in editing genomes. This would allow them to make cutting-edge advances in stem-cell research and medicine, which can’tbe accomplished in murine models alone. The embryos were never destined for reproduction, but there was an outcry and concerns the development could be a slippery slope towards designer babies.
Niakan wants to find and study the genes at play in the first few days of human fertilization.
Changing an embryo’s genes for “therapeutic purposes” is illegal in most countries since people could use the new technology to design their children.
The U.S.has imposed a moratorium on federally-funded research in this area, but in the UK, such experiments can be conducted for research purposes, provided scientists obtain a license.
The latest modification, referred to as CRISPR-Cas9, will probably eventually allow scientists to remove genetic issues by correcting flawed coding. The application comes months after a team of Chinese researchers became the first to announce they have altered DNA.
The researchers were attempting to modify the genes causing a blood disorder called β-thalassaemia. They fear that if these embryos could be grown to term, their new traits would be heritable, which will be a major ethical breach.
Others in the scientific community, however, held a different opinion. Kevin FitzGerald of Georgetown University Medical Center hopes that regulators would delay processing the request until public engagement can be accomplished.

The United State’s National Institutes of Health continues to ban any funding being used to genetically alter human embryos- viable or not.
