Immortalized porcine SSCs display limited differentiation in response to RA. a q-PCR analysis of PLZF, KIT and STRA8 transcripts in immortalized porcine SSCs with/without RA treatment. Data are presented as the mean ± SEM of three independent experiments. *: P < 0.05; **: P < 0.01. b Western blot analysis of PLZF, KIT and STRA8 proteins in immortalized porcine SSCs with/without RA treatment. β-actin is used as a loading control
