What does Nanog do? - Nature Reports Stem Cells - 0 views

  •  
    In embryos and induced pluripotent stem cells, Nanog sets the ground state of pluripotency Nanog, named after the fountain of eternal youth, is considered the key to pluripotency, but its role is puzzling: it can be deleted from embryonic stem cells without causing them to differentiate, and it is not among the collection of genes that can induce specialized cells to become pluripotent. Nonetheless, it does help human cells reprogram and can be used to separate incompletely reprogrammed cells from fully reprogrammed ones.

How to ID human pluripotency :The Scientist - 0 views

  •  
    Stem cell researchers must take more care in identifying true pluripotency in reprogrammed human cells, according to a study published online today (October 11) in Nature Biotechnology. The paper outlines strict molecular criteria for recognizing pluripotency, and warns that relying on just a single marker will muddle the field.

One step to human pluripotency :The Scientist [28th August 2009] - 0 views

  •  
    Researchers have regressed human stem cells to an embryonic state using just a single transcription factor, as opposed to the four factors previously needed to induce pluripotency in human cells, according to a study published online today (August 28) in Nature.

'Liposuction leftovers' easily converted to IPS cells, study shows - 0 views

  •  
    Globs of human fat removed during liposuction conceal versatile cells that are more quickly and easily coaxed to become induced pluripotent stem cells, or iPS cells, than are the skin cells most often used by researchers, according to a new study from Stanford's School of Medicine.

One-gene method makes safer human stem cells - health - 28 August 2009 - New Scientist - 0 views

  •  
    The goal of curing diseases like Parkinson's using cells generated from a patient's own body has come a step closer. Researchers have successfully reprogrammed human nerve cells back to an embryo-like state using just one gene.

The Niche: Stem cells, down to one factor - 0 views

  •  
    Differentiated human cells have been reprogrammed to an embryonic-like state with the addition of only one gene, rather than the standard four. This should advance techniques for the efficient production of high-quality patient-specific stem cells.

Tumor suppressor pulls double shift as reprogramming watchdog - 0 views

  •  
    A collaborative study by researchers at the Salk Institute for Biological Studies uncovered that the tumor suppressor p53 not only stops cells that could become cancerous in their tracks but also controls somatic cell reprogramming.
