Astroglia induce neurogenesis from adult neural stem cells
TLDR
These findings reinforce the emerging view that astrocytes have an active regulatory role—rather than merely supportive roles traditionally assigned to them—in the mature central nervous system.Abstract:
During an investigation of the mechanisms through which the local environment controls the fate specification of adult neural stem cells, we discovered that adult astrocytes from hippocampus are capable of regulating neurogenesis by instructing the stem cells to adopt a neuronal fate. This role in fate specification was unexpected because, during development, neurons are generated before most of the astrocytes. Our findings, together with recent reports that astrocytes regulate synapse formation and synaptic transmission, reinforce the emerging view that astrocytes have an active regulatory role—rather than merely supportive roles traditionally assigned to them—in the mature central nervous system.read more

TL;DR: Advances in the understanding of adult neurogenesis will not only shed light on the basic principles of adult plasticity, but also may lead to strategies for cell replacement therapy after injury or degenerative neurological diseases.

Astrocytes, from brain glue to communication elements: the revolution continues.

TL;DR: The recent recognition that astrocytes are organized in separate territories and possess active properties — notably a competence for the regulated release of 'gliotransmitters', including glutamate — has enabled us to develop an understanding of previously unknown functions for astroCytes.

Mammalian neural stem cells.
TL;DR: Before the full potential of neural stem cells can be realized, the authors need to learn what controls their proliferation, as well as the various pathways of differentiation available to their daughter cells.

CNS stem cells express a new class of intermediate filament protein.
TL;DR: The predicted amino acid sequence of the nestin gene product shows that nestin defines a distinct sixth class of intermediate filament protein, extending a model in which transitions in intermediate filament gene expression reflect major steps in the pathway of neural differentiation.
