Abstract

Mouse embryonic stem (ES) cells have the pluripotent ability to differentiate in vitro into various cell lineages, including neurons. Adding chick dorsal root ganglion (DRG) conditioned medium (CM) to the culture medium promotes the differentiation of ES cells into neurons. We determined the types of neurons that differentiate from ES cells. The addition of DRG-CM caused nearly half of all ES cells on the periphery of the colony sphere to differentiate into neurons. Immunofluorescence analysis showed that the neurons that differentiated from ES cells were mainly motor, GABAergic, serotonergic, and cholinergic neurons. Of particular note, flow cytometry showed that approximately 50% of βIII-tubulin-positive neurons were motor neurons. This indicates that DRG-CM induces ES cells to differentiate into motor neurons as target of DRG neurons (sensory neurons).
