Grading my 20 stem cell predictions for 2020

Knoepfler-The-Niche-stem-cell-blog-predictions-2020

Each year I metaphorically try to look into a crystal ball for stem cell predictions for the coming year and I did so for 2020, but the COVID-19 pandemic threw a monkey wrench into my predictions. It actually kind of blew some up. It also raised some interesting questions and dilemmas. For instance, do many …

New human genome editing (HHGE) academy report: solid, but key gaps

The-International-Commission-on-the-Clinical-Use-of-Human-Germline-Genome-Editing-HHGE

Something called, “The International Commission on the Clinical Use of Human Germline Genome Editing” has issued a new report on heritable human genome editing (HHGE). The Commission was convened by the U.S. National Academy of Medicine, the U.S. National Academy of Sciences, and the U.K.’s Royal Society. This post is my initial take on the summary of …

CRISPR often damages human embryo chromosomes

human-embryo-modification

Three new studies reported in preprints all show severe DNA damage to human embryos from CRISPR a surprisingly high percentage of the time including in some cases loss of heterozygosity (LOH). Anywhere from about a quarter to half of CRISPR’d embryos exhibited major genome damage. As readers of The Niche know, I never was a …

B+ on my report card on my 20 stem cell predictions for 2019

stem-cell-crystal-ball-predictions-1

Last year around this time I took my annual plunge to make 20 predictions for the coming year for the stem cell and regenerative medicine field. I even made a crystal ball graphic to highlight the complexity of the stem cell ecosystem into which these predictions were embedded (see image) for 2019. How’d I do? …

Calling Out Denis Rebrikov CRISPR Babies Plan

Denis-Rebrikov-1

A Russian Scientist named Denis Rebrikov told Nature and then other media including NPR last week that he plans to make CRISPR babies. In other words, babies with heritable genetic modifications. I don’t doubt that Rebrikov (pictured in ResearchGate image) might want to do this nor that he might try it, but rather I’m writing …

CRISPR baby moratorium grows likely with rising tide of support including from biotech

CRISPR-gene-edit-vs-mutation-1

Trying to make a CRISPR baby any time soon would be a really bad idea. How bad? Last December 3rd I penned a piece for STAT News arguing for a moratorium on the heritable use of CRISPR in humans. This potential future, radical application of “gene editing” is now often colloquially referred to as “CRISPR …

Counterpoints to Lovell-Badge & Daley’s CRISPR baby rationales

CRISPR-baby

Two prominent scientists, Robin Lovell-Badge and George Daley, have been amongst the most outspoken proponents of leaving the door open to heritable human genetic modification via CRISPR. While they each have articulated their reasons in somewhat different ways at times, their core reasons arguing in favor of future heritable CRISPR appear largely the same. In …

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 …

Why CRISPR baby production (if it happened) was unethical & dangerous

Jiankui-He-who-claims-CRISPR-baby-production

Reports are out that a scientist in China has been working to make a CRISPR baby for some time and supposedly has made twin genetically modified babies. I see this work as unethical and dangerous. Just a couple years ago when I published my book GMO Sapiens on potential use of CRISPR in a heritable manner …
