What are embryonic stem cells & where do they come from?

Knoepfler lab stem cells

What are embryonic stem cells and how do we scientists obtain them? My lab here at UC Davis School of Medicine has been doing research on embryonic stem cells for more than 14 years. You’ve come to the right place for expert answers on these very intriguing cells. What’s in this article Where do embryonic […]

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

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

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

STAP cells (stap細胞) are real deal says new Vacanti patent declaration

Vacanti-STAP-figure-2017

STAP is back? Really? No, I don’t believe so, but there’s an interesting development and twist on the STAP cell front. Just a few days ago on January 4, 2017 Dr. Charles Vacanti, the originator of the STAP cells concept, submitted a declaration to the USPTO affirming the belief that STAP cells are real and requesting that

New Mitalipov paper on stem cell mitochondria: challenge for IPS cell field?

Mitalipov-mitochondrial-mutations

A new paper from Shoukhrat Mitalipov’s lab on stem cell mitochondria points to a pattern whereby induced pluripotent stem (IPS) cells tend to have more problems if they are from older patients. New Mitalipov paper What does this paper mean for the stem cell field and could it impact more specifically the clinical applications of IPS
