BDNF Released from biodegradble microparticles elicits an increase in dendritic growth emerging from cortical neurons.
	Neurites emerging from neurospheres in PEG-PLA hydrogels after 14 days of culture (LIVE/DEAD membrane integrity assay).
	Beta-tubulin positive neurons cultured in PEG-PLA hydrogels after 14 days of culture (immunocytochemistry).
	Cells phagocytose biodegradable microparticles (that contain a fluorophore for visualization purposes) upon injection into the CNS.
