Differentiation of neuronal lineage of NHA cells resulted in presence of GABA-ergic and catecholaminergic cells. Immunocytochemistry data show presence of GABA-positive and TH-positive cells as derivatives of neural differentiation of NHA cells according to protocol 2 (a, b) and demonstrate that TH positive cells present β-III-TUBULIN expression (b).
