Single-cell RNA-seq of  motor neuron progenitors differentiated from mouse embryonic stem cell line HM1 by treatment with RA and SAG
To define the sequence of events that lead to the generation of somatic motor neurons (MNs), we took advantage of ESCs, which can be directed to differentiate into spinal neural progenitors (NPs) in vitro (Gouti et al. 2014). This method relies on the exposure of ESCs, cultured as a monolayer, to a brief pulse of Wnt signalling prior to neural induction. Subsequently, removal of Wnt signalling and exposure to retinoic acid (RA) results in the generation of NPs. Exposure of these NPs to Shh signalling agonist SAG induces the expression of genes expressed in the ventral spinal cord and the induction of MNs.
