It was intriguing last week to read about another advance in somatic cell nuclear transfer (SCNT)-based therapeutic cloning of human embryonic stem cells (hESC). The first such work was published last year by Mitalipov’s group from OHSU. This second paper to produce so-called nuclear transfer hESC (NT-hESC) made the important advance to show that it could […]

An international team of stem cell scientists has replicated human therapeutic cloning to make embryonic stem cells via somatic cell nuclear transfer (SCNT). The team was led by Drs. Dong Ryul Lee of CHA Stem Cell Institute in Korea and Robert Lanza of Advanced Cell Technology (ACT). They reported the advance in the Chung, et

We need medical innovations, but what is the appropriate way for agencies like the FDA to regulate the process and fight bogus interventions based solely on hype? Without innovation, medicine becomes stagnant and hope fades for patients who have any one of numerous conditions that are currently inadequately addressed by medicine. I can relate on

What’s the latest surprise on the STAP cell front? There have been many unexpected turn along the way in the past few weeks of the rollercoaster ride the stem cell field is on related to STAP stem cells, the super powerful stem cells reportedly (in two papers in Nature) made “simply” by exposing cells to

There have been many interesting developments in stem cells in 2013, but to me the biggest event by far was the first ever successful somatic cell nuclear transfer (SCNT)-based human therapeutic cloning. This approach generated apparently genetically normal human embryonic stem cells (hESC), an astonishing accomplishment. There are two kinds of human cloning: therapeutic and reproductive.
