Figure 4.
Restorations of cholinergic ((A,C), n = 8–10/group) and dopaminergic ((B,D), n = 8–10/group) nervous systems following F3 or F3.ChAT cell transplantation. RT-PCR (A,B) and quantitative analyses (C,D) of the mRNA expression of cholinergic and dopaminergic components. Black: young animals (7 weeks old); red: aged animals; green: aged animals transplanted with F3 cells (1 × 106 cells every month); blue: aged animals transplanted with F3.ChAT cells (1 × 106 cells every month). ChAT: choline acetyltransferase. VAChT: vesicular acetylcholine transporter. ChT1: choline transporter 1, m1-AChR: muscarinic 1 acetylcholine receptor. nAChR: nicotinic acetylcholine receptor. AChE: acetylcholinesterase. GAPDH: glyceraldehyde-3-phosphate dehydrogenase. TH: tyrosine hydroxylase, VMAT2: vesicular monoamine transporter 2. DAT: dopamine transporter, DR: dopamine receptor. * Significantly different from young rats (p < 0.05). # Significantly different from aged rats (p < 0.05). + Significantly different from F3 treatment (p < 0.05).
