In vitro-propagated neural stem cells require specific culture conditions to retain their multipotentiality or differentiate into adult neural cells. However, a defining signature of cells that differentiate upon defined conditions into desirable neuronal/glial phenotype remains insufficiently characterized. We applied SRM to measure levels of protein markers routinely used to probe neural differentiation in a panel of well-described conditions. Our method helped to identify the presence of pluripotent, multipotent as well as lineage-committed cells [1]. Since the capacity of the measurement allows to quantify differentiation markers together with other relevant proteins simultaneously, we aimed to develop assays for additional markers that would provide a system-wide view. We browsed manually curated databases and selected 360 proteins that report on specific biological processes on the basis of literature evidence. The proteins are mechanistically employed in biological processes of neural differentiation, including cell proliferation, autophagy, apoptosis, etc. Such an expanded assay could allow the optimization of novel specific propagation and differentiation protocols, further increasing the accuracy in detecting targeted cell populations.
