Research Identifies Protein that Regulates Key Fate Decision in Cortical Progenitor Cells

Researchers solved an important piece of one of neuroscience's outstanding puzzles: how progenitor cells in the developing mammalian brain reproduce themselves while also giving birth to neurons that will populate the emerging cerebral cortex, the seat of cognition and executive function in the mature brain.

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.

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.

Spinal Cord Regeneration Barriers Removed with Cancer Drug

The researchers claim Taxol was effective in promoting regeneration of injured spinal cord nerve cells in rats following spinal cord lesions. Only a few weeks following the spinal cord lesions and Taxol application, rats showed significant improvement in movements.
