Mitalipov Nature pub review: IPSC & SCNT for mitochondrial disease

Mitalipov-IPSC-paper

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 …

Cool paper by Cowley Lab on the role of HDACs in ES cells

Cowley-HDAC-knockout-278x3001

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 …

Adult human therapeutic cloning of embryonic stem cells by SCNT

Human-SCNT1

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 …

Review of New ACT Paper on hESC-derived MSCs

advanced-cell-technology-150x1501

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 …

Cool Cell Stem Cell Paper From Ishii Team on Histones & Reprogramming

Two of my favorite things are stem cells and histones. When they both come together in one paper and it’s in my favorite journal, Cell Stem Cell, you’ve got my full attention. My own lab is especially interested in the roles of histones and Myc in stem cells. So when I saw a paper a paper from …

Transdifferentiation makes a major advance: direct reprogramming of fibroblasts to oligodendrocyte progenitors

Back-to-back papers (here and here) in Nature Biotechnology report the transdifferentiation (now often simply referred to as “direct reprogramming”) of plain old fibroblasts into brain cells called oligodendrocyte progenitor cells (OPCs). OPCs are a remarkably useful kind of brain cell that generates myelin, which insulates nerves. OPCs are thought to have great therapeutic potential for …

Stem cell field reacts somewhat cautiously to mammary pluripotent stem cell paper

An interesting paper just came out in PNAS reporting the apparent presence of pluripotent stem cells in the adult breast. The paper is Roy, et al. and is from Thea Tlsty’s outstanding lab at UCSF. I have read the paper and it seems very solid technically to me. The finding has stimulated some powerful metaphors. …
