The cellular form of the prion protein guides the differentiation of human embryonic stem cells into neuron-, oligodendrocyte-, and astrocyte-committed lineages.

abstract：:Prion diseases are subacute neurodegenerative diseases that affect humans and a range of domestic and free-ranging animal species. These diseases are characterized by the accumulation of PrP (Sc), an abnormally folded isoform of the cellular prion protein (PrP (C)), in affected tissues. The pathology during prion dise...
