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.

Tissue engineers can use mesenchymal stem cells derived from fat to make cartilage, bone, or more fat. The best cells to use are ones that are already likely to become the desired tissue. Brown University researchers have discovered that the mechanical properties of the stem cells can foretell what they will become, leading to a potential method of concentrating them for use in healing.

A
research team at Rutgers University has been able to take a new
pharmacological approach to activate the immune cells to prevent cancer
growth through stimulation of the opiate receptors found on immune
cells.

New research findings show that embryonic stem cells unable to fully compact the DNA inside them cannot complete their primary task: differentiation into specific cell types that give rise to the various types of tissues and structures in the body. Researchers from the Georgia Institute of Technology and Emory University found that chromatin compaction is required for proper embryonic stem cell differentiation to occur.

In
order to reactivate silenced genes, a cell needs to remove certain
“off” markers called methyl groups from the DNA. Scientists have
recently shown that this process involves an intermediate step and an
enzyme that also plays a role in the development of blood cancer. The
finding could lead to new ideas for cancer-fighting therapies.

A research group headed by the Tokyo
University of Science has demonstrated the possibility of regenerating
functional hair adult stem cells. The bioengineered hair follicles grown
in mice show full functionality, including surrounding host tissue
connections and nerve fibers. The finding could represent a substantial
advance in the development of next-generation of organ replacement
regenerative therapies.

The
Texas Medical Board on Friday approved new rules on experimental stem
cell therapies such as the one Gov. Rick Perry underwent during back
surgery last year, despite objections they don't do enough to protect
patients and could led to an explosion of doctors promoting unproven,
expensive treatments.

Yale University 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 is different in humans than in mice, highlighting the importance of research using human embryonic stem cells.

Scientists
in Germany have succeeded in obtaining somatic stem cells from fully
differentiated somatic cells without them first passing through the
pluripotent stage. To perform this conversion, researchers combined a
number of different growth factors, which are proteins that guide
cellular growth.

Huntington's disease, the debilitating congenital neurological disorder that progressively robs patients of muscle coordination and cognitive ability, is a condition without effective treatment, a slow death sentence. But if researchers can build on new research, a special type of brain cell forged from stem cells could help restore the muscle coordination deficits that cause the uncontrollable spasms characteristic of the disease.
