May 17, 2010 | Pluripotent Stem Cells

by Stuart P. Atkinson

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...

March 1, 2010 | Haematopoetic Stem Cells

By Carla B. Mellough

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).

February 26, 2010 | Pluripotent Stem Cells

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...

by Lyle Armstrong

Induced pluripotent Stem Cells (iPSC) are widely believed to share many of the characteristics of Embryonic Stem Cells (ESC) and as such have been credited with the potential to revolutionise regenerative medicine. The potential benefit of iPSC exists because of their genetic similarity to the individual from whom they were derived, implying that if...
