Neurotrophic factors promote cholinergic differentiation in human embryonic stem cell-derived neurons.

ABSTRACT: Cholinergic neurotransmission is essential for many important functions in the brain, including cognitive mechanisms. Here we demonstrate that human embryonic stem (hES) cells differentiate into a population of neuronal cells that express the cholinergic enzyme choline acetyltransferase and homeobox proteins specifying neuronal progenitors of ventral telencephalic lineage. These differentiated cells express transcripts for cholinergic alpha(3), alpha(4) and alpha(7) nicotinic acetylcholine (ACh) receptor subunits and for M1, M2 and M3 muscarinic acetylcholine receptor (mAChR) subtypes. Stimulation with brain-derived neurotrophic factor, neurotrophin-3, ciliary neurotrophic factor and nerve growth factor increases the proportion of cholinergic neurons. These cholinergic receptors also media
