“…Possible functions might be to facilitate such escape by weakening the zona around the blastocyst, to dissolve a discarded zona remaining in a position where it might interfere with implantation, andlor to play some other role in the implantation process. Studies in other mammals have provided evidence (which was sometimes circumstantial) for the involvement of proteinases of trophoblastic andlor uterine origin in the dissolution of extracellular embryonic coats and, in several species, in the initiation of implantation as well (Pinsker et al, 1974;Denker, 1977Denker, ,1980Denker, ,1983 et al., 1978;Denker and Tyndale-Biscoe, 1986;Perona and Wassarman, 1986;Yamazaki and Kato, 1989).…”

“…Discussions are going on as to what extent hardening of the 'zona' should be of concern in human IVF-ET [De Vos and Van Steirteghem, 2000;Magli et al, 1998]. There is ample evidence from studies in various animal systems, notably the rabbit and the mouse, that proteinase systems (of the trophoblast as well as the uterus) are involved in hatching of the blastocysts by causing weakening and at least partial dissolution of the coats, with most data being available for the rabbit [for review, see Denker, 1977;Denker et al, 1989] and the mouse and rat [Dabich and Andary, 1976;Hoversland and Weitlauf, 1982;Menino and O'Claray, 1986;Mintz, 1972;Perona and Wasserman, 1986;Pinsker et al, 1974;Rosenfeld and Joshi, 1981;Yamazaki et al, 1994; with respect to the unclear role of the plasminogen activator-plasmin system, see Carroll et al, 1993;Liedholm and Åstedt, 1975]. Whether comparable proteinase systems are also involved in human blastocyst hatching is unknown but would appear quite probable.…”

“…After Mintz (1972) and Pinsker et al (1974) first suggested that the enzyme responsible for hatching might also be an implantation initiation factor, Gonzales and Bavinster (1995) predicted that the enzyme responsible for focal hatching in vitro might really be the enzyme responsible for facilitating blastocyst attachment and invasion. Through our discovery of ISP1, we have confirmed this additional role for the hatching enzyme in facilitating implantation competence.…”
