Germline stem cells: Public Row Ensues

From Nature News

Recent correspondence in Nature has brought into question claims of the pluripotent nature of human adult germline stem cells (haGSCs) generated from human testicular tissue ...

New egg screening technique may boost the success rate of IVF

From BBC

A new egg screening technique pioneered by Care Fertility and reported at the European Society of Human Reproduction and Embryology (ESHRE) conference in Rome, can predict genetic problems in 90% of cases. Use of this technique could lead to increases in pregnancy rates from IVF.   Read the entire story...

From Nature News

Nature News reports that a group from University of Glasgow, UK, has created human pluripotent cells using a virus alone.   These findings, from Andrew Baker and his colleague Nicole Kane, were reported at the International Society for Stem Cell Research annual meeting in San Francisco, California.   Read more from Nature...

Researchers, overseen by Bruce Gelb and Ihor Lemischka at the Mount Sinai School of Medicine (New York), have described the derivation of two separate induced pluripotent stem cell (iPSC) lines from LEOPARD syndrome patients.  LEOPARD syndrome is a multifaceted autosomal-dominant developmental disease (closely related to Noonan syndrome), which can...

Although induced pluripotent stem cell (iPSC) generation continues to forge ahead, the early molecular mechanisms behind the reprogramming process remain poorly understood. In an attempt to understand these mechanisms, Bhutani and colleagues utilised...

Traditional techniques for the generation of induced pluripotent stem cells (iPSCs) require the use of integrating viral particles to deliver the required factors for efficient reprogramming. Reprogramming efficiency, however, lies in the region of only 0.02 to 1% of target cells, and this falls to much lower levels when non-integrational means of...

The secret to eternal youth has been under pursuit for centuries. But now, results reported in Nature by a group at Harvard University shed new light on just how the ageing process might be co-ordinated across tissues and, astonishingly, that we may be able to reverse it (Mayack et al., 2010).

By Stuart P. Atkinson

DNA methylation is an epigenetic mechanism which allows the regulation of gene expression, genome structure and genome stability. Current dogma dictates that DNA methylation mainly occurs on cytosines at CG di-nucleotides, which are found clustered together forming dense patches within the genome. Such regions are known as CpG islands and usually...
