Scientists from U.S Have Successfully Edited Human DNA By using CRISPR technology, a team of scientists from Oregon has edited the genes in human embryos and made huge steps in reaching new results. They tried to eradicate genetically transmitted diseases.

CRISPR isnt a new technology but it has started being used in human genetics recently. CRISPR is a DNA sequence that was found in bacteria and could protect the immune system, detecting and destroying invaders such as viruses that try to infect the bacteria. Scientists try to use CRISPS so that they target mutations that would cause diseases, this way treating them from the root of DNA encoding.

Major issues were solved using gene-altering technology.

The lead researcher Shoukhrat Mitalipov from the Oregan Health and Science University stated that they solved their previous problems they had with CRISPR gene-altering technology. In 2015 they faced a problem using this technology, resulting in embryos suffering a condition named mosaicism due to CRISPR that aligned edited and unedited cells.

In the early 2017 China went through a similar problem at the Hospital Guangzhou Medical University.

They tried to repair abnormal embryos and the results were not satisfying. They also used normal embryos resulted from immature eggs and fertilized them with sperm that carried genetic disease. Before the cell division started, they injected CRISPR and out of 6 embryos, half were repaired but with a problem: two of them were suffering from mosaicism.

New ground has been broken later by Mitalipov and his team.

In Oregon Mitalipov and his team were able to inject CRISPR into the eggs while they fertilized them with sperm and avoided moisaicism. They also solved the problem of genetic disease transmission, correcting the genes.

Were still waiting for official results from the Oregon Health and Science University and Shoukhrat Mitalipov through a published paper which will soon appear in a scientific journal.
