    Abstract: A method for inducing differentiation of stem cells is provided to reduce the costs for differentiation by using inexpensive lithium chloride as a differentiation-inducing agent, induce the differentiation phenomenon similar as a normal development process in vitro culture, and increase differentiation efficiency. A method for inducing differentiation of stem cells comprises the steps of: (a) forming embryoid bodies from the stem cells through floating aggregation culture method; and (b) adding 5-20 mM of lithium chloride to the embryoid bodies and culturing them in a culture vessel containing an extracellular substrate such as laminin, collagen or Engelbreth-Holm-Swarm. Further, liver cell separating medicine is added into the embryoid bodies.
