Neural Stem Cells Regenerate Axons in Severe Spinal Cord Injury

Researchers were able to regenerate an astonishing degree of axonal growth at the site of severe spinal cord injury in rats. Results were then replicated using two human stem cell lines, one already in human trials for ALS. “We obtained the exact results using human cells as we had in the rat cells,” said Tuszynski.

New Gene Variants Found to Raise Risk of Neuroblastoma and Influence Tumor Progression

Researchers have discovered two gene variants that raise the risk of the pediatric cancer neuroblastoma. This is the first study to link known cancer-related genes HACE1 and LIN28B to neuroblastoma. The study broadens understanding of how gene changes may make a child susceptible to this early childhood cancer, as well as causing a tumor to progress.

Researchers Identify Potential New Approach for Improving Quality of Life for ALS Patients

By increasing the signaling activity of a protein called muscle skeletal receptor tyrosine-protein kinase (MuSK), researchers were able to keep nerve cells attached to muscle longer into the progression of the disease in a mouse model of ALS.

Astrocytes Control the Generation of New Neurons from Neural Stem Cells

Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.

Neuroscientists Find Brain Stem Cells that May Be Responsible for Higher Functions, Bigger Brains

A neuron’s fate was thought to be determined by the timing of its birth date. Neuroscientists recently showed that there is a distinct stem cell progenitor that gives rise to upper layer neurons, regardless of birth date or place.

Brain’s Stem Cells Eavesdrop to Find Out When to Act

Working with mice, Johns Hopkins researchers say they have figured out how stem cells found in a part of the brain responsible for learning, memory and mood regulation decide to remain dormant or create new brain cells. Apparently, the stem cells “listen in” on the chemical communication among nearby neurons to get an idea about what is stressing the system and when they need to act.
