EGCG Protects against 6-OHDA-Induced Neurotoxicity in a Cell Culture Model

Figure 2

Prevention of TH⁺ neuronal loss by EGCG induced by 6-OHDA in primary cultures. Cells were pretreated with EGCG (1, 10, and 100 μM) for 2 h followed by 6-OHDA (10 μM) for 24 h. Immunocytochemistry was used to measure the TH⁺ cells (arrow, (a), (b), (c), and (d)). Quantification data on TH⁺ number (e) and neurite length (f). Values are mean ± SEM, . Bars without common letters differ. ; .
