In a new, thought-provoking paper today in Nature, Shoukhrat Mitalipov and a multi-institutional team report a significant advance toward potential novel ways to treat mitochondrial diseases. What are these illnesses? Mitochondrial diseases are rare, but devastating disorders caused by genetic mutations. Today they are largely impossible to treat in meaningful ways other than palliative care. Some of the mutations causing these diseases are in nuclear DNA, while others are in the mitochondrial DNA (mtDNA). The main current approach to prevention is preimplantation genetic diagnosis (PGD) …Read More

It was great being a postdoc in Bob Eisenman’s Lab at the Hutch in Seattle. I loved it.  Bob is a great mentor (see more on my experience there here) and the scientific interactions in the lab were wonderful. It’s been fun and interesting to follow the work of my fellow former Eisenman lab members over the years. For example, another former postdoc from the Eisenman lab, Shaun Cowley, has a lab that is doing some exciting research on the role of histone deacetylase (HDACs) in …Read More

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) and reported the advance in the Chung, et al. paper today in the journal Cell Stem Cell entitled “Human Somatic Cell Nuclear Transfer Using Adult Cells”. The cells expressed pluripotency markers (see Figure 1A at left) and …Read More

Advanced Cell Technology (ACT; $ACTC) has a new paper out on using human embryonic stem cells (hESC) to make MSCs with potentially powerful therapeutic potential. The paper, entitled Mesenchymal stem cell population derived from human pluripotent stem cells displays potent immunomodulatory and therapeutic properties, was published in the journal Stem Cells and Development. What’s the scoop on this paper and this area of adult stem cell preclinical/clinical research? It’s an interesting, notable paper. At the same time there are some areas in the paper that could have been …Read More
