Beth Shapiro is chief scientific officer at Colossal Biosciences Plans to genetically bring mammoths and other vanished animals back to life have scientific stakes far beyond the imagery of Jurassic Park The basic technologies are all there, but perfecting them will still require a lot of work. Thanks to pioneers such as Nobel laureate Svante Pääbo, first we learned how to recover DNA from fossils, rearrange the fragments worn away over centuries and millennia, and compare them with the sequences of the closest living relatives. Then came CRISPR, the Nobel Prize-winning technique: using this t ..read more

Richard Slayman – Credit New York Times This is good news, to be celebrated with caution. The first patient with a CRISPR-edited pig kidney has left the hospital. A little over two weeks have passed since the surgery at Massachusetts General Hospital, but according to U.S. press reports, Richard Slayman is well enough to have been discharged. Fingers crossed, then, for this 62-year-old man who, thanks to a xeno-rene, no longer needs dialysis. Before him, two patients had the courage and opportunity to have a pig heart transplanted, both of whom died after a few weeks: David Bennett from a porc ..read more

It could take a while to bring the first CRISPR products to our tables, but it is always a good time to see what progress is being made in the labs. Here are some novelties, reported by Isaaa: high-fiber barley, aromatic soy milk, extralong-grain wheat, TiGER strawberries, and my favorites: seedless, thornless, and higher-yielding blackberries and black raspberries ..read more

If you are in Cambridge, Massachusetts, don’t miss the live dance performance to be held at the MIT Museum on March 16th. The Choreography of CRISPR is all about “twisting, cutting, inserting, copying, repeating, palindromes, and cluster”, “an intricate dance of spiraling and folding patterns” (you can watch a minute from the première on the facebook page of the NYC-based contemporary dance company Pigeonwing Dance; choreography by Gabrielle Lamb, original music by James Budinich ..read more

The goal is to treat unborn children as early as possible, before their disease causes irreversible damage. But the ambition is to do so without heritable DNA changes, that is, by targeting only somatic tissues and avoiding sex cells. Fetal genome editing, then, differs from embryo editing, which has raised so much controversy in recent years. The best way to understand how far it has come and how much remains to be done is to tell the story of the scientist most committed to this challenge. The opportunity is provided by a longread published in STAT, where Tippi MacKenzie’s biography is inte ..read more

There is no doubt that this is good news: on February 7, the European Parliament approved the Commission’s regulatory proposal on New Genomic Techniques, covering also CRISPR plants. Some of the approved amendments (particularly the one on genetic modification of polyploid plants) have the effect of improving the text, others risk being a problem and should be reconsidered during the trilogue with member states (particularly the requirement to label all final products, even if they do not contain foreign genes). The European Parliament also brought in the issue of non-patentability of NGT pla ..read more

Anyone interested in advanced therapies is familiar with the acronym CAR-T. These are T lymphocytes modified (also with the help of CRISPR) to better recognize and attack cancer cells, and they have already proven to be a successful strategy for blood tumors. Now hopes are high that a similar approach may also prove useful for multiple sclerosis, which is an autoimmune disease. The idea is to use CAR-Ts to prevent B lymphocytes from attacking nerve cells, including in the brain. The first clinical trial is recruiting patients in the U.S. Read more in Nature. Let’s come to the use of New Genom ..read more

According to Fyodor Urnov, she should be added to “the pantheon of names inscribed in golden letters in the history of biomedicine.” That list includes other pioneering patients such as James Phipps (the boy vaccinated by Edward Jenner), Albert Alexander (the first human treated with penicillin), Louise Brown (the first test tube baby) and Emily Whitehead (the first recipient of CAR-T cells). Now the CRISPR Journal made the unusual decision to put her on the cover. In July 2019, Victoria Gray became the first U.S. sickle cell patient to receive the experimental treatment for sickle cell disea ..read more

Credit: Bing Image Creator Not only sickle cell anemia, now thalassemia as well. On January 16, the Food and Drug Administration completed the approval process for the second type of hemoglobinopathy too, while the European Medicines Agency is expected to give the green light in the coming months. It took just over a decade to go from the invention of the Cas9 genetic scissors to the first approved treatment, and the excitement over the milestone achieved in record time is more than justified. Yet an article in MIT Technology Review has already turned the spotlight on the next challenges. The ..read more
