1-30. (canceled)
A method for expanding midbrain Dopaminergic Progenitor cells (mDAPs), comprising contacting the mDAPs with an expansion medium on a culture surface coated with a coating matrix combination, wherein the coating matrix combination comprises:
- (a) a first coating matrix that supports cell adhesion for the mDAPs;
- and,
- (b) a second coating matrix that improves the expression of mDAP-specific markers during the expansion and passaging of the mDAPs as compared to that in the absence of the second coating matrix, wherein the second coating matrix comprises a Notch agonist.
