An international team led by researchers at the University of California, San Diego School of Medicine reports that a single injection of human neural stem cells produced neuronal regeneration and improvement of function and mobility in rats impaired by an acute spinal cord injury (SCI).

A tiny Australian songbird may hold the answer to discovering the biological source of stuttering, which affects 3 million Americans and is notoriously difficult to treat. A team of Michigan State University scientists will investigate the brain and behavior of the zebra finch in the first in-depth study of whether stuttering stems from a lack of rhythm.

Chris Thomson, a second year veterinary student at University of Minnesota’s College of Veterinary Medicine, has been awarded the 2013 AMP/Michael D. Hayre Fellowship in Public Outreach. Chris’ program will focus on student-to-student outreach at veterinary schools and conferences across America.

Two Colorado State University professors have developed a nanostructured surface coating for bone that is expected to help improve the lifetime of bone implants. The research, if proven, could someday help someone replace injured or diseased bone segments without losing the affected limb.

Salamanders’ immune systems are key to their remarkable ability to regrow limbs, and could also underpin their ability to regenerate spinal cords, brain tissue and even parts of their hearts, scientists have found.
In research published today in the Proceedings of the National Academy of Sciences researchers from the Australian Regenerative Medicine Institute (ARMI) at Monash University found that when immune cells known as macrophages were systemically removed, salamanders lost their ability to regenerate a limb and instead formed scar tissue.

While the effects of acute stroke have been widely studied, brain damage during the subacute phase of stroke has been a neglected area of research. Now, a new study by the University of South Florida reports that within a week of a stroke caused by a blood clot in one side of the brain, the opposite side of the brain shows signs of microvascular injury.

When the brain's primary "learning center" is damaged, complex new neural circuits arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways — often far from the damaged site.

Scientists at Oregon Health & Science University and the Oregon National Primate Research Center (ONPRC) have successfully reprogrammed human skin cells to become embryonic stem cells capable of transforming into any other cell type in the body. It is believed that stem cell therapies hold the promise of replacing cells damaged through injury or illness. Diseases or conditions that might be treated through stem cell therapy include Parkinson’s disease, multiple sclerosis, cardiac disease and spinal cord injuries.

Into brains of newborn mice, researchers implanted human “progenitor cells.” These mature into a type of brain cell called astrocytes. They grew into human astrocytes, crowding out mouse astrocytes. The mouse brains became chimeras of human and mouse, with the workhorse mouse brain cells – neurons – nurtured by billions of human astrocytes. Human astrocytes certainly inspired the mice. Genetically engineered "astrocytes" have improved rodents' memories and learning capabilities.

Epilepsy that does not respond to drugs can be halted in adult mice by transplanting a specific type of cell into the brain, UC San Francisco researchers have discovered, raising hope that a similar treatment might work in severe forms of human epilepsy.

UCLA life scientists have identified a gene previously implicated in Parkinson's disease that can delay the onset of aging and extend the healthy life span of fruit flies. The research, they say, could have important implications for aging and disease in humans.

UCSF scientists controlled seizures in epileptic mice with a one-time transplantation of medial ganglionic eminence (MGE) cells, which inhibit signaling in overactive nerve circuits, into the hippocampus, a brain region associated with seizures, as well as with learning and memory. Other researchers had previously used different cell types in rodent cell transplantation experiments and failed to stop seizures.

Whitehead Institute Founding Member Rudolf Jaenisch, who helped transform the study of genetics by creating the first transgenic mouse in 1974, is again revolutionizing how genetically altered animal models are created and perhaps even redefining what species may serve as models.

Scientists have identified a gene that keeps our nerve fibers from clogging up. Researchers in Ken Miller’s laboratory at the Oklahoma Medical Research Foundation (OMRF) found that the unc-16 gene of the roundworm Caenorhabditis elegans encodes a gatekeeper that restricts flow of cellular organelles from the cell body to the axon, a long, narrow extension that neurons use for signaling. Organelles clogging the axon could interfere with neuronal signaling or cause the axon to degenerate, leading to neurodegenerative disorders. This research, published in the May 2013 Genetics Society of America’s journal GENETICS, adds an unexpected twist to our understanding of trafficking within neurons.

Jackson Laboratory scientists announced Tuesday that they will use mice as clinical stand-ins, or “avatars,” for human patients with cancerous tumors to help test and create genetically-tailored cancer treatments.

When scientists began sequencing the zebrafish genome in 2001, the model organism was a favourite of biologists studying early development of the brain and other organs. Few others found much use for the small, stripy fish with see-through embryos. More than a decade later, with its genome finally unveiled today, the zebrafish (Danio rerio) has become the go-to animal for researchers studying many human diseases — as well as those investigating new treatments.
