Abstract
The present invention provides a vehicle for delivering various chemicals, compositions and proteins to stem cells and embryoid bodies. The vehicle may be biocompatible and biodegradable polymer microparticles. Typically the particles will contain at least a growth factor for delivery to the embryoid bodies, and generally the growth factor induces differentiation of the cells in the embryoid body along a specific lineage. The present invention also provides methods for directing differentiation of the cells in the embryoid body.
