Effect of a single P4 exposure on the viability of PC-12 and SK-N-AS (A) and primary cortical neurons and HFF-1 cells (B). Cells were exposed to different concentrations of P4 (0.1, 1, 5, 10, 20 and 80 µmol/L) for 48 h. The stock solution of P4 was prepared in DMSO (final concentration <5 µL/mL medium). Cell death was measured by MTT assay. Data are expressed as means ± standard deviation (SD) of three independent experiments. Significant difference: *P < 0.05 compared with vehicle group.
