Japan conditionally approves new IPS cell-based heart study

Yoshiki-Sawa-IPS-cells-stem-cells-heart-diseease

Where do things stand with IPS cell translational research? The newest development is that regulators in Japan just have given conditional approval to an Osaka University team to an induced pluripotent stem (IPS) cell-based study for ischemic heart disease. For years IPS cell-based products have been on-again off-again in active clinical study for macular degeneration, work […]

Ian Wilmut, who cloned Dolly, opens up about his Parkinson’s Disease

Ian-Wilmut

One of the most famous living biological scientists, Sir Ian Wilmut, just announced that he has Parkinson’s Disease. I wish him the best in dealing with this illness. Wilmut is very well-known for having cloned the first mammal, Dolly the Sheep. This work followed on the earlier breakthrough by Sir John Gurdon of cloning the

Analysis: human immunity to Cas9 bigger #CRISPR therapeutic hurdle than off-targets?

Cas9-immunity-pre-print

Some in CRISPR-Cas9-land who are focused on potential future clinical applications are kind of rejoicing or at least sighing a breath of relief. This upbeat swing in the atmosphere (from investors especially) was sparked by retraction of that paper, the one initially reporting tons of supposed off-target CRISPR-Cas9 activity in mice, which turned out to be a “nothing

Journal club: Jaenisch lab paper on epigenetic CRISPR-Cas9 rescue of Fragile X in a dish

Liu-et-al.-Figure-6C-Fragile-X-CRISPR-Cell-e1519673510685

There’s much more to CRISPR-Cas9 than just gene editing and a new paper from the lab of Rudy Jaenisch in Cell highlights that in an exciting way. It reports epigenetic reversal of a Fragile X Syndrome phenotype in induced pluripotent stem cell (IPSC) neurons. Fragile X Syndrome is a neurological disorder in boys resulting from CGG repeat

Just one word placentas: Can Celularity live up to hype?

Celularity-e1519061558939

I’ve been blogging about stem cells now for about 8 years and the recent level of hype about and fluffy media coverage of Celularity, the biotech spun out of Celgene, ranks right up here with the most extreme past cases I’ve seen. What is Celularity and who is its leadership? It’s a new biotech focused

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

Is monkey cloning a breakthrough or a bad idea?

Monkey-clones

Is monkey cloning a good idea? We’re about to find out. A new Cell paper today reports the first cloning of monkeys via somatic cell nuclear transfer (SCNT), raising many questions. The paper from a team led by Qiang Sun is entitled, “Cloning of Macaque Monkeys by Somatic Cell Nuclear Transfer.” The highlight bullet points

Adverse event in IPS cell (ips細胞) trial for vision loss in Japan: initial perspectives

Takahashi-IPS-transplant

A team of researchers at RIKEN and Kobe City Medical Center reported at a press conference today a serious adverse event in a clinical trial participant receiving an induced pluripotent stem cell (IPS cell)-based therapy for vision loss. According to Japan Times and Yahoo! Japan (in Japanese), the patient in question in the IPS cell

Keep calm & CRISPR on: perspectives on report of human Cas9 immunity

Keep-calm-CRISPR-on

The news that CRISPR-Cas9 gene editing in its current form may not work in a substantial fraction of people due to many of us having immunity to Cas9 came as a shock to many, but if you think about it, maybe it’s not so surprising. I don’t see it as the end of the world. A (preprint) from
