Figure 3From: Increased GDF9 and BMP15 mRNA levels in cumulus granulosa cells correlate with oocyte maturation, fertilization, and embryo quality in humansComparison of OSFs mRNA levels between the groups with and without high-quality embryo. The relative expression of GDF9 mRNA (a) in the groups with high-quality embryos. (b) The relative expression of BMP15 mRNA in the groups without high-quality embryos. *P<0.05.Back to article page
