The effects of RECA on the proliferation of Schwann cells. The cell viability for each concentration of RECA was analyzed using the MTT assay at different time points (24 h, 72 h, 120 h and 168 h of RECA treatment). The absorbance was read at 570 nm and the value represents the mean ± SEM (n = 3). * indicates significant differences between the viability of Schwann cells treated with RECA at ≥1200 μg/ml compared to the viability of control (untreated Schwann cells) after 168 h in culture, p < 0.05
