Cell culture characterization

	DAPI	TH or MAP2	% TH or MAP2 positive cells
Locus coeruleus	656	349	53.20
Substantia nigra	857	377	43.99
Hippocampus	1711	909	53.1

Quantification of the percentage of cells immunopositive to tyrosine hydroxylase (TH) or microtubule-associated protein 2 (MAP2, Hippocampus) in relation to the total number of cells, indicated by DAPI, in cells cultures of locus coeruleus, substantia nigra and hippocampus. Count was performed in 16 fields of each culture plate of a total of 4 plates per experiment.
