Table 1 Effect of eFSH and FCS on nuclear maturation and cumulus expansion.

From: Cumulus expansion, nuclear maturation and connexin 43, cyclooxygenase-2 and FSH receptor mRNA expression in equine cumulus-oocyte complexes cultured in vitro in the presence of FSH and precursors for hyaluronic acid synthesis

Maturation medium Nuclear maturation rate % (n° of oocytes) Cumulus expansion rate % (n° of oocytes)
Control 70% (21) a 42% (21) a
Control + 1 μg/ml eFSH 62% (21) a 48% (21) a
Control without BSA with 20% FCS 74% (27) a 83% (29) b
