FIG. 9.
Effect of 24-h RA exposure followed by a 48-h recovery in cultured neonatal testis is shown. Real-time RT-PCR analyses show Stra8 and Cyp26a1 expression levels. Error bars represent standard errors of the means (n ≥ 7). Asterisks indicate significance (P < 0.05), and reported values represent calculated P values relative to vehicle control.
