| Research Abstract |
For the research of cell transplantation therapy for Parkinson's disease, the method of coculture with mouse derived PA6 cells has been used for the differentiation of embryonic stem (ES) into dopaminergic (DA) neurons. For the clinical application, nevertheless, it is impossible to use PA6 cells derived from mouse, the molecular mechanism of the method should be revealed.
We investigated the roles of Wnt-related molecules and revealed that PA6 cells secreted Wnt5a and sFRP1, and both of them cooperatively induced neural stem cells from mouse ES cells. These results will lead to understanding the mechanism of SDIA and provide a new chemically defined method of DA neuron induction from ES cells.
