Scientists
and administrators at the University of California, Berkeley, and the Broad Institute of M.I.T. and Harvard, in Cambridge, Massachusetts, are both fighting fiercely to win a patent fight over CRISPR/Cas9 technology, a powerful new method of editing genomes with
precision and ease.
Etopia
News has been
covering the recently-announced approval by the U.K.’s Human Fertilisation & Embryology Authority
to Dr. Kathy Niakan and her team at the Francis Crick Institute in London to use this CRISPR/Cas9 technology to study
the earliest stages of human embryonic development. Etopia News has covered discussion of this use of biotechnology by the California Institute for Regenerative Medicine(CIRM),
the creation of customized human embryonic stem cells (hESCs) by this method,
the ethical issue of getting informed consent to use donor embryos that does or
doesn’t include explicit permission to perform CRISPR/Cas9-mediated alterations
to the embryo’s genome,
and even the declining of comment on the HFEA’s decision by a candidate for
Governor of California in 2018, Gavin Newsom.
Now, the
very institutions fighting over the right to claim that they invented
CRISPR/Cas9 have both also declined to comment on the use of this technique to
edit germline cells in viable human embryos, as approved by HFEA and discussed
by CIRM, and whether researchers need to get specific and explicit permission
from embryo donors before experimenting on them with CRISPR/Cas9.
The Broad
Institute said it wanted to see how things played out with HFEA and Dr. Niakan’s
work before saying anything. Paul
Goldsmith, a Media Relations Specialist there, wrote to Etopia News,
saying in an e-mail:
“Thanks
for your inquiry. Unfortunately, none of our researchers here are working with
human embryos (as I'm sure you're aware). We're all watching how things unfold
in the UK at the moment, and would rather withhold comment for another time.”
Robert
Sanders, Manager, Science Communications in the Office of Media Relations at UC
Berkeley, provided some interesting information about the work being done there
by Dr. Jennifer Doudna,
one of the two parties being credited by their institution as the legitimate
inventor of CRISPR/Cas9, along with Dr. Feng Zhang at the Broad. Here’s what he told Etopia
News:
“Prof. Doudna does not work with embryonic cells and would
not be the right person to address this question. None of her colleagues work
with embryos either; they are focused on fixing genetic disease in children and
adults, not the embryo. In addition, her schedule is very full and she has to
turn down many media requests such as yours. I hope you are able to find an
expert on embryonic research who can answer your questions.”
So, while one
or both of these researchers may have invented the CRISPR/Cas9 biotechnology, so
far, neither of them has publicly expressed their views on whether using it to
modify the genomes of viable human embryos is a good idea or not. Their media spokespersons also seem to share a
strong desire to make it clear that neither of them is engaged in any research
involving human embryos.
The search
for an “expert on embryonic research” who is also willing to take a position on
questions about the use of CRISPR/Cas9 in embryo editing and the specificity of
permission needed to authorize this technique’s use on donated embryos, will
continue.
