In the case of mice, EGF promoted the formation of blastocoeles (Wood and Kaye, 1989; Paria et al., 1994) and increased blastocyst development rate of bovine embryos (Coskun et al., 1991; Harper and Brackett, 1993), as well as the cell number of blastocysts (Lee and Fukui, 1995) so as to increase embryo development rate (Wei et al., 2001).
