Table 4 Effect of glutamine 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 50% (67) a,b 32% (67) a
Control + 1 μg/ml eFSH 34% (86) a 60% (86) b

Control + 2 mM glutamine + 1 μg/ml eFSH 34% (80) a 51% (80) a,b
Control without BSA with 20% FCS 53% (68) b 94% (68) c
