Table 2 Effect of precursors for hyaluronic acid synthesis 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 56% (34) a 53% (32) a
Control + precursors 61% (31) a 48% (31) a
Control + precursors + 1 μg/ml eFSH 59% (30) a 57% (29) a
Control without BSA with 20% FCS 65% (31) a 84% (31) b
