From various news sources

“Liver disease kills more people in the UK than diabetes and road deaths combined, claiming more than 16,000 lives in 2008. It is the only cause of death that is still increasing year-on-year. Numbers of liver disease deaths have increased by 12% since 2005. Last year around 644 liver transplants from deceased donors were carried out...

By Carla Mellough

Continuing on with our recent focus on microRNA (miRNA) and induced pluripotency (see ‘Reprogramming the methods that induce pluripotency’), a recent article published in the September advance issue of Nucleic Acids Research from David Wu’s group (WJWU and LYNN Institute for Stem Cell Research) in California may shed light on the mechanisms that govern somatic...

By Carla Mellough

The clinical applicability of induced pluripotent stem cells (iPSC) has been limited by the inefficiency of reprogramming methods, modification of the genome using most reprogramming protocols, and the lack of failsafe differentiation protocols to then generate functional differentiated phenotypes from iPSCs to provide patient-specific cell types for...

MicroRNAs (miRNAs) are endogenous RNAs that direct the repression of protein coding genes. The way in which miRNAs elicit their effects on protein production has been an issue of great debate, whether they act to decrease translational efficiency, decrease messenger RNA (mRNA) levels or both. Recent results published in Nature from the laboratory of David...

Non-viral genetic modification of cells is a relatively inefficient process, be it modifying adult cells or in the generation of induced pluripotent stems cells (iPSC). It has been suggested that transposon-based methods of gene transfer may overcome this limitation, but this technique has been plagued by inefficiency problems. However recent work has...

We all know that vitamin C is important for keeping us healthy through its many activities including its capacity as an antioxidant and its involvement as an enzyme co-factor in collagen synthesis. Indeed this second property is the basis of the most obvious consequence of vitamin c deficiency that was the demise of many an eighteenth century mariner known as Scurvy which messes up the...

By Stuart P. Atkinson

Gene by gene, we are beginning to unravel and understand those members of the pluripotency network which give embryonic stem cells (ESCs) their identity. Other than giving us an understanding of the molecular networks, signalling pathways and regulatory mechanisms which exist in ESCs, such knowledge is also allowing us to make more and more critical...

The first official clinical trial using stem cells to treat patients with spinal injury is now underway (also see ‘US give Geron Go-ahead for ESC Trial for Spinal Cord Injury’). The first patient to receive the trial treatment was enrolled on Monday at Shepherd Center in Atlanta, Georgia. Another 9 patients who have recently suffered spinal cord injuries will be enrolled from 6 other potential...

Research published in the 30th September edition of Cell Stem Cell reports that human induced pluripotent stem cells (hiPSCs) can be rapidly and efficiently derived with messenger RNA (mRNA). This research, from the laboratory of Derrick Rossi shows that daily transfection of differentiated human cells with modified synthetic mRNAs encoding the four canonical Yamanaka factors KLF4, c-MYC,...

With each month’s Featured Lab Series, the Stem Cells Portal extend an invitation to one of the Featured Lab members to contribute a short review of a paper of their interest for feature on the Stem Cells Portal. This month, Minh Hong from the Kaufman Laboratory has contributed an article which focuses on a key paper published recently in PNAS that addresses the further evolution of...
