Human embryos study development. For the first time scientists have used gene-editing techniques on human embryos to know that how they developed. The work suggests that a protein calledOCT4 has additional roles in human embryos compared with those of mice. But biologists say that it is more important as a proof of principle; previous human embryos editing research has focused instead on correcting faulty genes.
The new experiments, published today in nature, are also a first test of the UK carefully crafted embryos editing research regulations, which require researchers to undergo a review by the national Human Fertilization and Embryology Authority need a license before going forward.In London, Kathy Niakan, a developmental of biologist at the Francis Crick Institute, applied in 2015 to use the CRISPR editing technique on human embryos to know more about the genes active early development. The researchers planned firstly focus on OCT4, known as a marker for pluripotent stem cells that can become all tissues in the body.
