4 possible roles for stem cell therapy besides cell replacement

stem-cells-drug-delivery

Historically, the main route of proposed healing via stem cell therapy was cell replacement. In this way of thinking the transplanted cells engrafted (took up home) in the patient’s tissue and replaced dead or diseased cells. However, interest continues to grow in other possible modes of healing by stem cells that don’t rely on cell […]

Context for my Nature piece on redefining “gene edit” to be more precise

CRISPR-gene-edit-vs-mutation-1

When I say “gene edit” or “genome editing”, what’s the first thing that pops in your mind? It will depend on who you are. For many lay people until a few weeks ago when the world heard about He Jiankui‘s claim of CRISPR’d babies they may not have had anything pop in their heads when

He Jiankui didn’t really gene edit those girls; he mutated them

CRISPR-gene-edit-vs-mutation-1

Did Chinese researcher He Jiankui really CRISPR gene edit the CCR5 gene in two embryos producing twin baby girls? In my opinion the answer is “no”, but probably not for the reason you might think at first. He proclaims gene edits He claimed he had made twin baby girls with “gene edits”, which I feel is unethical

Stem cell news bites: Astellas trial, cystic fibrosis claim, a few cool papers

Matoba-et-al-Figure-2c-2018

Stem cell news is always burbling up, sometimes right there in front of us on the web and other times via networks of people. Astellas news. Some may remember there used to be this pioneering stem cell biotech called ACT, which then became Ocata, and finally was acquired by the big company Astellas. One of

Mixed Nuffield Council Report Too Aspirational on Human Genetic Modification

Designer-baby

It’s an odd confluence of events this week that (A) the Nuffield Council, an ethics think tank, gives a thumbs up in a new report to heritable human genetic modification that would probably include using CRISPR in the same week that (B) a new paper reports that CRISPR can cause unpredictable genomic damage and several other concerning reports

Surprising reason why human cloning may produce someone else

Daisuke-Takakura-human-cloning

“If I’m going to the trouble of cloning myself, I want the clone to be a copy of me!” I’m imagining what someone might say if they were told that their expensive and ethically dubious personal cloning efforts produced a clone that was somebody else instead of them. Even if the clone was very similar
