Figure 7. Immunocytochemistry study of phosphorylated p44/42 MAPK (Thr202/Tyr204) in NGF- or hot aqueous extract-treated PC-12 cells after 48 h of incubation.
(A) Negative control, cells in complete F-12 K medium only. (B) Positive control, cells treated with 50 ng/ml of NGF. (C) Cells treated with 25 μg/ml of hot aqueous extract. (D–F) Cells were pre-treated with 10 μM U0126 prior to the treatment with NGF or hot aqueous extract. Phosphorylated p44/42 protein stained cell body in green. DAPI stained nuclei in blue. Scale bar = 50 μm.
