Review of Mitalipov Nature paper: cloned ES cells vs iPS cells

NT-ESC

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 […]

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

Review of Obokata STAP cells Nature papers

STAP-stem-cells

In two Nature papers (here and here) published today researchers report the astounding finding of reprogramming differentiated cells back to a pluripotent or even totipotent state simply by exposing the cells to extreme environmental stress, creating cells they called STAP cells. Update: see more thoughts on STAP stem cells here. STAP cells: stressing the cell

100% reprogramming efficiency reports Jacob Hanna

A team at the Weizmann Institute of Science in Israel led by Jacob Hanna reports today near perfect reprogramming efficiency to make induced pluripotent stem cells (iPSCs) by eliminating a single factor called Mbd3 from the cellular equation. On first glance, the Nature article (Rais, et al.) seems to be all about boosting cellular reprogramming efficiency to close

Stem cell journal club: dishing on Nature paper on making iPS cells inside mice

What if you could reprogram cells inside of an organism to a different fate and, for instance, make IPS cells? We can, right? But when most of us think about making induced pluripotent stem (iPS) cells, we imagine it all happening in a little plastic dish in our labs or in our colleague’s labs, not
