The relative expression patterns of apoptosis (A) and pluripotency (B) related genes in 7-day-old embryos.

<p>The concentration of etoposide used in this experiment was 25 μg/mL. The mRNA abundance was calculated relative to the reference gene GAPDH. Data are from 3 independent replicates with 20 embryos in each group. ETO, etoposide; * P < 0.05; N.S., not statistically significant (P > 0.05).
