The potential impact of olfactory stem cells as therapy reported in Cell Transplantation

A study characterizing the multipotency and transplantation value of olfactory stem cells, as well as the ease in obtaining them, has been published in a recent issue of Cell Transplantation (20:11/12), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/.

New stem cell technique promises abundance of key heart cells

Cardiomyocytes, the workhorse cells that make up the beating heart, can now be made cheaply and abundantly in the laboratory.  Writing this week (May 28, 2012) in the Proceedings of the National Academy of Sciences, a team of Wisconsin scientists describes a way to transform human stem cells — both embryonic and induced pluripotent stem cells — into the critical heart muscle cells by simple manipulation of one key developmental pathway. The technique promises a uniform, inexpensive and far more efficient alternative to the complex bath of serum or growth factors now used to nudge blank slate stem cells to become specialized heart cells.

From stem cell to brain cell – new technique mimics the brain

A new technique that converts stem cells into brain cells has been developed by researchers at Lund University. The method is simpler, quicker and safer than previous research has shown and opens the doors to a shorter route to clinical cell transplants.

Stem-cell-growing surface enables bone repair

—University of Michigan researchers have proven that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer.

Growth factor in stem cells may spur recovery from MS

A substance in human mesenchymal stem cells that promotes growth appears to spur restoration of nerves and their function in rodent models of multiple sclerosis (MS), researchers at Case Western Reserve University School of Medicine have found.

Study using stem cell therapy shows promise in fight against HIV

UC Davis Health System researchers are a step closer to launching human clinical trials involving the use of an innovative stem cell therapy to fight the virus that causes AIDS.

In a paper published in the May issue of the Journal of Virology, the UC Davis HIV team demonstrated both the safety and efficacy of transplanting anti-HIV stem cells into mice that represent models of infected patients. The technique, which involves replacing the immune system with stem cells engineered with a triple combination of HIV-resistant genes, proved capable of replicating a normally functioning human immune system by protecting and expanding HIV-resistant immune cells. The cells thrived and self-renewed even when challenged with an HIV viral load.

Improved adult-derived human stem cells have fewer genetic changes than expected

A team of researchers from Johns Hopkins University and the National Human Genome Research Institute has evaluated the whole genomic sequence of stem cells derived from human bone marrow cells—so-called induced pluripotent stem (iPS) cells—and found that relatively few genetic changes occur during stem cell conversion by an improved method. The findings, reported in the March issue of Cell Stem Cell, the official journal of the International Society for Stem Cell Research (ISSCR), will be presented at the annual ISSCR meeting in June.

New embryonic stem cell line will aid research on nerve condition

The University of Michigan’s second human embryonic stem cell line has just been placed on the U.S. National Institutes of Health’s registry, making the cells available for federally-funded research. It is the second of the stem cell lines derived at U-M to be placed on the registry.

Yale researchers show how embryonic stem cells orchestrate human development

- Yale researchers show in detail how three genes within human embryonic stem cells regulate development, a finding that increases understanding of how to grow these cells for therapeutic purposes.

This process, described in the April 6 issue of the journal Cell Stem Cell, is different in humans than in mice, highlighting the importance of research using human embryonic stem cells.

Stem cell study aids quest for motor neurone disease therapies

A breakthrough using cutting-edge stem cell research could speed up the discovery of new treatments for motor neurone disease (MND).

The international research team has created motor neurones using skin cells from a patient with an inherited form of MND.
