Early during my postdoc I was primarily interested in the role of Myc genes both in cancer and in stem cells, work that later included embryonic stem cells. These cells are often called ES cells. At first I first started studying N-Myc in neural stem cells using a conditional knockout approach. However, soon after I was […]

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

By Jeanne Loring A stem cell anniversary: 18 years ago today that the US initiated funding of human embryonic stem cell research. August 9, 2001 was a big day for me. George W. Bush was the US president, and it was an understatement to say that I was not very fond of his policies; but

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

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

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

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.
Four or five years ago the top stem cell story was the battle over federal funding of human embryonic stem (ES) cell research in the U.S. by James Sherley and Theresa Deisher. They were the two opponents of ES cell research making the most national headlines. Nature did a whole piece back then on Deisher

Bombshell news in the stem cell field as Ocata Therapeutics (OCAT; formerly Advanced Cell Technology or ACT) is reportedly to be acquired by Astellas Pharma, Inc. The offer for purchase of OCAT will be $8.50/share or almost $380 million. For more details see this detailed PDF from Astellas. This quote on the deal form Ocata: “Paul

Just how good are human embryonic stem (ES) cells made by therapeutic cloning via nuclear transfer, with the successful technique first reported by the lab of Shoukhrat Mitalipov at OHSU last year? How do they compare to induced pluripotent stem (iPS) cells or traditional ES cells made from IVF embryos? A new paper in Nature directly tackles these
