Human reproductive applications are probably the most talked about potential
application of genome editing technologies and raise some of the most complex ethical concerns.
Now we know more, and while the paper demonstrates the possibility
of genome editing of human embryos, it raises more questions than it answers.
The technique offers, through high - level editing operation, a method to address the existing
issues of genome editing.
In the
case of genome editing of human embryos, however, it seems likely that technology will make the next move.
The first of these will focus on the potential
use of genome editing in human reproduction to avoid the transmission of heritable genetic conditions, and the second on livestock to improve systems of animal husbandry and food production.
The Council will now begin work on two further inquiries addressing the ethical and practical questions raised by possible uses
of genome editing in different fields.
To alter the stem cells, Kan's team turned to the CRISPR - Cas9 system, a super-efficient
method of genome editing based on an ancient bacterial «immune system».

A single treatment involving
injection of a genome editing cocktail prevented progressive hearing loss in young animals that would have otherwise gone deaf, Howard Hughes Medical Institute (HHMI) Investigator David Liu and colleagues report December 20, 2017 in the journal Nature.
What makes Crispr so exciting is that, thanks to its precision, the tool has opened up a world of innovation to research facilities that previously wouldn't have been able to handle the expenses or
complexities of genome editing.
He says some of his colleagues have dismissed the need for such engagement because they contend it's still too hypothetical: Scientists and clinicians can't yet safely and efficiently do the
types of genome editing that are being envisioned.
«We'll continue to investigate mechanisms by which neural tissue bridges to repair the spinal cord in zebrafish, taking advantage of the
power of genome editing to examine other factors,» said Poss.
As with other technologies and innovations, the potential benefits and
harms of genome editing might not be distributed equitably, and some people are worried that negative effects could cause discrimination, injustice or disadvantage to certain individuals or groups.
«Moreover, we need to clarify the differences between older genetic engineering techniques and modern genome editing, and shed light on various issues towards social
acceptance of genome edited crops.»
A trio of scientists from the University of Wisconsin - Madison and the Morgridge Institute for Research participated in an international think tank this month on the
intersection of genome editing technology and national security.
Izpisua Belmonte is uniquely qualified to speak to the
ethics of genome editing in part because, as a member of the committee on human gene editing of the National Academies of Sciences, Engineering and Medicine, he helped author the 2016 roadmap «Human Genome Editing: Science, Ethics, and Governance.»
There are companies out there already doing it and figuring out the safety profile, so there's increasing clinical infrastructure that we could potentially piggyback on as we work out more
details of genome editing,» Marson said.
The research complies with recommendations to study the basic cellular
processes of genome editing, keeping an eye on possible future clinical use but only so long as the work does not attempt to create a human pregnancy.
We are excited to be working with the Caribou management team as they seek to expand the commercial applications
of their genome editing platform across therapeutics, agriculture, and other industries.»
«This is important biotechnologically, because if you look at if from the
angle of genome editing, the delivery of small genes into cells is much easier than the delivery of large genes,» said Rotem Sorek of the Weizmann Institute of Science in Israel who was not involved in the work.
«The ability to correct disease - causing mutations is one of the primary
goals of genome editing,» said Zhang, a core institute member at the Broad Institute, investigator at the McGovern Institute for Brain Research at MIT, and the James and Patricia Poitras Professor in Neuroscience at MIT.
He is a biophysicist software developer interested in
bioinformatics of genome editing using CRISPR / Cas9 (see WGE), algorithms for tracking lab processes and sequence pattern recognition.
Development and application
of genome editing tools in grass plants Dr. Bing Yang, Associate Professor, Plant Biology, Iowa State University.
The research and development activities conducted by TEFOR - TACGene aims to provide the community with advanced expertise in tools and
strategies of genome editing and develop original solutions for specific issues (such as improving KI efficiency).
The National Institutes of Health have announced that it will launch an effort to remove barriers from the
adoption of genome editing for treating patients.
The developments and applications
of genome editing with custom endonucleases began in 2005 with Zinc - Finger Nucleases (ZFN), followed in 2011 by the TALE - Ns, for «Transcription - Activated like Effector Nucleases».
Introducing new antibody chains is becoming practically routine in the
field of genome editing; genetic engineering of antibodies for human health purposes has steadily advanced over the past few decades using many model organisms including rodents, cattle, and even chickens.
For example, in my
area of genome editing, there are huge amounts of data produced at every step in a given process, and data science helps a scientist apply that data in the laboratory.
«When assessing the security
implications of genome editing, it will be particularly important to include the voices of all stakeholders,» says Dominique Brossard, professor of life sciences communication and Morgridge affiliate.
In her pioneering work, Doudna co-invented a technology that combines CRISPR with a protein called Cas9, vastly improving the precision and
efficiency of genome editing.
The Münster immunologists found a test - tube alternative for this, too: they used the molecular biological
method of genome editing to systematically «cut out» the gene segment relevant for VLA4 and produce the appropriate «deficient» immune cells.
Derived mostly from human embryonic kidney 293T (HEK293T) and HeLa cell lines, EdiGene Knockout (KO) Cell Lysates have been optimized through the use
of genome editing technology and validated at the genomic level through PCR and Sanger - sequencing techniques to ensure the accuracy and knockout of the target gene.
There are many potential applications
of genome editing in human pluripotent stem cells (hPSCs) including the generation of knockout and reporter cell lines.
By contrast, the use
of genome editing is soaring — and its most famous tool, CRISPR — Cas9, has already gained traction in industry, agriculture and medicine, notes George Church, a genome scientist at Harvard Medical School in Boston, Massachusetts, who works with CRISPR.
A group of European scientists has founded an international association to discuss and provide guidance on the ethical use
of genome editing, a technique with the potential to transform everything from food production and human health to science itself.
«They are the first direct demonstration of use
of genome editing to correct point mutations in two diseases with real phenotypic effect.»
