After stem cell hype, a new hope for heart therapy in Minneapolis PDF Print E-mail
Tuesday, 09 August 2011 02:04

For many years, Bill Garten lived what he calls "the casino life."

As an electronics technician, Garten worked on slot machines and was often asked to drive across the Upper Midwest on a moment's notice to verify that machines had properly awarded big jackpots.

IBN Promises Safer Stem Cell Therapy for Cancer Patients PDF Print E-mail
Thursday, 04 August 2011 00:50

The future of regenerative medicine lies in harnessing the potential of the human body to renew and repair itself. Now, scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a new genetic engineering technique that promises safer stem cell therapy for cancer patients.

Thursday, 04 August 2011 00:42
The University of Michigan’s stem cell research scientists have created new stem cell lines that will use adult stem cells, instead of the controversial embryonic stem cells, to study psychological and neurological disorders.
Hope For MS Sufferers With World Stem Cell Trial PDF Print E-mail
Tuesday, 02 August 2011 00:14

A PIONEERING series of stem cell experiments on patients is set to bring new hope of treatment for multiple sclerosis sufferers.

The £10million study will investigate whether damage to the brain and spinal cord caused by active MS lesions can be slowed, halted or even reversed.

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.
Precision Gene Targeting in Stem Cells Corrects Disease-Causing Mutations PDF Print E-mail
Saturday, 30 July 2011 00:29
Using two distinct methods, Whitehead Institute researchers have successfully and consistently manipulated targeted genes in both human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells (adult cells that have been reprogrammed to an embryonic stem cell-like state).
Scientists create human-animal hybrids in secret research PDF Print E-mail
Thursday, 28 July 2011 00:44

Hybrids were produced in secret by researchers looking into cures for a range of diseases.

London: British scientists have created more than 150 human-animal hybrid embryos in British laboratories.

Report Calls for Regulation of Animal-Human Hybrid Experiments PDF Print E-mail
Tuesday, 26 July 2011 01:42

Experiments that create animal-human hybrids by implanting human material in lab animals should be more rightly regulated, a group of British scientists said in a new report.

Scientists Complete First Mapping of Molecule Found in Human Embryonic Stem Cells PDF Print E-mail
Tuesday, 26 July 2011 01:11
Stem cell researchers at UCLA have generated the first genome-wide mapping of a DNA modification called 5-hydroxymethylcytosine (5hmC) in embryonic stem cells, and discovered that it is predominantly found in genes that are turned on, or active.

Scientists in Japan successfully produced living sperm from mice stem cells.

The research, published in an online academic journal Cell, sheds hope as it is a crucial step in treating human infertility.

Investigators Claim FOXO1 Plays Critical Role in hESC Pluripotency PDF Print E-mail
Thursday, 04 August 2011 00:46

Scientists claim the forkhead box O (FOXO) transcription factor FOXO1 is an essential component of the cellular control mechanism that maintains pluripotency in human embryonic stem cells (hESCs). Studies by a Mount Sinai School of Medicine-led team suggest the protein may directly control OCT4 and SOX2 gene expression by activating the genes’ promoters.

Cellular Power Plant Genome Mutates When Reprogrammed: Genetic Changes in Mitochondrial Genome of Human Induced Pluripotent Stem Cells PDF Print E-mail
Tuesday, 02 August 2011 00:52
Induced pluripotent stem cells (iPS cells) are truly talented multi-taskers. They can reproduce almost all cell types and thus offer great hope in the fight against diseases like Alzheimer's and Parkinson's. However, it would appear that their use is not entirely without risk: during the reprogramming of body cells into iPS cells, disease-causing mutations can creep into the genetic material.
Vet's Treatment Could Be a Cause For Cell-ebration PDF Print E-mail

FOR a group one race horse, a partially torn tendon doesn't just mean a break from racing for up to a year, the risk of re-injury is also high.

So when a prizewinning filly was recently referred to Sydney veterinarian Robin Bell he recommended the horse undergo stem cell therapy.

Signal Explains Why Site of Origin Affects Fate of Postnatal Neural Stem Cells PDF Print E-mail
Saturday, 30 July 2011 00:30
New research may help to explain why the location of postnatal neural stem cells in the brain determines the type of new neurons that are generated. The research, published by Cell Press in the July 28 issue of the journal Neuron, demonstrates that a signaling pathway which plays a key role in development also actively regulates the fate of neural stem cells in the adult brain.
Dental Breakthrough: Mouse Stem Cells Grow Teeth PDF Print E-mail
