Effects of ganglioside GD1a during IVC on development of porcine embryos. (A) Representative photographs of blastocysts according to treatment concentrations (0.1 and 0.2 µM) of GD1a. Scale bar = 100 µm. Rates of cleavage stage (B) and blastocyst stage (C) in the absence or presence of different concentrations of GD1a. Data in the bar graph represent the means ± SEM of three independent experiments. Differences were considered significant at *p < 0.05.
