TLDR
In this paper, a method for producing genetically modified neural cells comprises culturing cells derived from embryonic, juvenile, or adult mammalian neural tissue with one or more growth factors that induce multipotent neural stem cells to proliferate and produce multipotent NSC progeny which include more daughter NSCs and undifferentiated progeny that are capable of differentiating into neurons, astrocytes, and oligodendrocyte.Abstract:
A method for producing genetically modified neural cells comprises culturing cells derived from embryonic, juvenile, or adult mammalian neural tissue with one or more growth factors that induce multipotent neural stem cells to proliferate and produce multipotent neural stem cell progeny which include more daughter multipotent neural stem cells and undifferentiated progeny that are capable of differentiating into neurons, astrocytes, and oligodendrocytes. The proliferating neural cells can be transfected with exogenous DNA to produce genetically modified neural stem cell progeny. The genetic modification can be for the production of biologically useful proteins such as growth factor products, growth factor receptors, neurotransmitters, neurotransmitter receptors, neuropeptides and neurotransmitter synthesizing genes. The multipotent neural stem cell progeny can be continuously passaged and proliferation reinitiated in the presence of growth factors to result in an unlimited supply of neural cells for transplantation and other purposes. Culture conditions can be provided that induce the genetically modified multipotent neural stem cell progeny to differentiate into neurons, astrocytes, and oligodendrocytes in vitro.read more

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.

GDNF: a glial cell line-derived neurotrophic factor for midbrain dopaminergic neurons
TL;DR: In embryonic midbrain cultures, recombinant human GDNF promoted the survival and morphological differentiation of dopaminergic neurons and increased their high-affinity dopamine uptake and did not increase total neuron or astrocyte numbers or transmitter uptake.

A glial progenitor cell that develops in vitro into an astrocyte or an oligodendrocyte depending on culture medium
TL;DR: It is suggested that fibrous astrocytes and oligodendrocyte develop from a common progenitor cell and provide a striking example of developmental plasticity and environmental influence in the differentiation of CNS glial cells.
