Figure 2From: Neuritogenic effect of standardized extract of Centella asiatica ECa233 on human neuroblastoma cells Representative photomicrograph of IMR-32 cells using phase contrast. (A) non-treated control, (B) BDNF 100 ng/ml, (C-F) ECa 233 0.1, 1, 10 and 100 μg/ml respectively (scale bar = 50 μm). Cells treated with BDNF and ECa 233 at the concentrations of 1, 10 and 100 μg/ml showed relatively longer neurite length.Back to article page
