Lisa Ikemoto on Human Germline Genetic Modification

ikemoto-lisa

This guest piece on Human Germline Genetic Modification is by Lisa C. Ikemoto, Professor, U.C. Davis School of Law. I have been following the reports about genetic editing technology with concern. The fact that some scientists are calling for moratoria on gene editing of human embryos heartens me. Frankly, I had little confidence that any …

Proposed Moratorium on Genetic Modification of Human Germ Cells

sperm-and-egg

One of the hottest topics in the biomedical world in 2015 is heritable human genetic modification including via germ cells. There is an unsettling sense that genetically modified human germ cells and eventually GMO human beings are likely coming even if science and society are not ready for it. There are a hodgepodge of laws against human …

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 …

Poll: heritable CRISPR tried in humans in next 10 years?

CRISPR-baby

Heritable CRISPR to be tried in humans sooner or later…or never? Will someone somewhere in the world try to use CRISPR gene editing or related technology to introduce heritable genetic changes into actual human beings in the next decade? I’m not talking about gene editing viable human embryos just for research which is already ongoing, …

Why we shouldn’t view the human embryo as a gizmo even in the CRISPR era

human-embryo-modification

My first job in science was as a lab technician at UCSD School of Medicine and a big part of that job was growing cells called HUVECs or human umbilical vein endothelial cells. We isolated and grew the HUVECs from umbilical cords that we retrieved from the maternity ward of the UCSD hospital, which first …

7 tech hurdles to human germline CRISPR

Human-crispr-challenges

Human germline CRISPR raises major bioethical considerations, but what about technical issues? Setting aside the many ethical issue about the general idea of human modification itself, could this really work? Yes in theory it could, but there are some very tough technological challenges that could and likely would cause failures or unacceptable outcomes at many steps …

Countering that Pro-Heritable Human CRISPR WSJ Piece

human-embryo-modification

It’s germline, heritable human CRISPR time, right? Wrong. But the particularly enthusiastic supporters of heritable human CRISPR often cite hypothetical benefits in glowing terms, but either don’t mention risks or strongly downplay them. These fans also tend to leave alternative, proven and safe technologies such as preimplantation genetic diagnosis (PGD) out of the discussion or …

Why Mitalipov’s ‘magic’ room for human embryo CRISPR may give us pause

Shoukhrat-Mitalipov

The debate over whether the main conclusions of the Nature paper on human embryo CRISPR led by Shoukhrat Mitalipov’s lab at Oregon Health Sciences University (OHSU) are correct remains unresolved. Note that Nature just added an editorial alert just above the references section to their paper: “Updated online 02 October 2017. Editorial Note: Readers are alerted that some …

1st Knockout Human Embryos Made with CRISPR: My Take on the Pub

Fogarty-Fig-3d-human-embryo-CRISPR-e1505774206656

Scientist make knockout human embryos with CRISPR? Today we see a new Nature paper (Fogarty, et al.) on CRISPR “gene editing” of human embryos, this time from the UK from Kathy Niakan’s group. Niakan got UK permission about 18 months ago to CRISPR healthy human embryos so they’ve been hard at work since. Because Fredrik …

Mulling over that Mitalipov human embryo CRISPR pub, still many questions

human-embryo-modification

What really happened at the DNA level in the experiments in that high-profile CRISPR of human embryos paper from a team led by Shoukhrat Mitalipov at OHSU? Is the team right that they successfully conducted CRISPR of human embryos to correct a mutant gene, as they reported in their Ma, et al. Nature paper? Or is the Egli, …
