"Liver on a chip" — the perfect test environment to test CRISPR
Source:
The Most famous not today editor CRISPR genome have already proved their effectiveness. However, the technology is quite young and requires further study the effects on living organisms. Traditionally CRISPR tested on animals or human cell lines, however, a group of scientists from the University of Arizona proposes to use for these purposes, another promising technology — "organs on a chip". In particular the new platform Liverchip.
Organs-on-chip is a small device with microtubules and human cells. Tubes forming a complex structure and transmit substances, simulating the work of the living body. They are very often used for different tests (mainly for the study of drugs), but to combine on the chip with the editor of genome scientists occurred for the first time.
CRISPR allows researchers quite easy to edit the set of genes in order to achieve the desired result, however, according to one of the study's authors Samira Kiani, this may bear the danger.
"it is possible that CRISPR can be a source of unintended consequences in the future. You can face many consequences of such mutations and autoimmune reactions. It is likely that the use of the system will create some "inappropriate" changes in the genome that will affect the entire DNA code. Thus we can obtain a variety of side effects such interference."
To study the effects of the experts and want to use the organ chips. It's one thing — to edit the genome, and quite another — learn how edited cells will be myself "feel" in the body.
"the Ultimate goal is to create a system that can predict the tissue reaction to therapy using CRISPR. In the long term we hope to be able to create a safe methods of the use of genome editor, which allows to develop methods of treatment."
Well, the liver in this case was not chosen by chance, because a huge portion of diseases associated with impaired metabolism of this body and many researchers agree that the liver will be the body which will begin with mass gene therapy in humans.
