What are totipotent stem cells & what can they do?

Multipotent & totipotent vs pluripotent stem cells, very early human embryos totipotent stem cells

Sometimes patients or my students ask me, “What are the best stem cells?” what information are they looking for? I think they often are looking for the most powerful stem cells so perhaps they should be asking, “What are totipotent stem cells?” Other times it seems what patients specifically want to know is what might …

Trump, GOP hypocrisy on Regeneron COVID-19 fetal, stem cell work

293T-HEK-cells-Trump-fetal-stem-cells-sm

Are Trump and the Republican Party showing major hypocrisy over Trump’s use of experimental COVID-19 therapies in part developed by Regeneron using embryonic and fetal cells? The Internet is kind of blowing up over this. Trump’s collision with stem cells For example, people are directly confronting Trump on Twitter over his recent all caps tweet …

Lessons for today’s science from when embryonic stem cell research was illegal in US

James-Sherley

We kind of take for granted these days that embryonic stem cell research can proceed without any restrictions, at least at the federal level. However, in the early days of blogging here on The Niche the big debate and battle were over federal funding of embryonic stem cell research. Things got very complicated and for …

US Senate bill would ban embryonic stem cell research

embryonic-stem-cell-research-funding-ban

Here we go again with people trying to ban funding of embryonic stem cell research. Really? Yes, including according to a new article from the Catholic News Agency. Who is trying to get this ban? Some Republicans in The U.S. Senate. I’ve wondered for years if the Trump Administration might take action against embryonic stem …

New stem cell pubs including artificial human embryo work

Fig-4d-Nat-Cell-Bio-2019-Simunovic-et-al

In this post I list some recent interesting stem cell and science pubs including artificial human embryo research. Engineered human embryo research continues. Scientists for years have been advancing the types of embryo-like structures made from both human and other creature’s cells. In a new Nature Cell Bio pub entitled, “A 3D model of a …

Possible safety concerns from new stem cell, RPE vision loss study report

Figure-1-Mehat-et-al.-AAO-Journal-2018-810x1024-1

With stem cells for vision loss, first we want to be sure a treatment won’t make things worse. Several teams around the globe are rigorously studying stem cell-based approaches to vision loss via regulatory-compliant studies including for macular degeneration with some results cautiously upbeat on safety from early phase analyses, but data from a new study on …

Stem cell transplants: hIPSC and hESC behave similarly in brain & often fuse with host cells

Martinez-Cerdeno-Figure-6

What happens following pluripotent stem cell transplants into the brain? Are human IPS and ES cells going to function similarly in this context? We recently published a new translational paper on the behavior of human pluripotent stem cells when transplanted into the adult mouse brain in collaboration with my great UC Davis colleague, Dr. Veronica Martinez-Cerdeno. …
