Notes:
We have previously demonstrated that newly synthesized proteins are secreted into the mouse blastocoel [Dardik and Schultz (1991): Biol Reprod 45:328-333]. In the present study we examine the effect of transforming growth factor-α (TGF-α) on these proteins. We observe that TGF-α stimulates secretion of these newly synthesized proteins into the blastocoel and apical medium, which faces the zona pellucida, by about 65%. Although one-dimensional gel electrophoretic analysis does not reveal any marked differences in the patterns of newly synthesized proteins secreted into the blastocoel in response to TGF-α, zymography reveals a marked stimulation in the secretion of several gelatinases into the blastocoel and apical medium. These results suggest additional functions for TGF-α in mouse preimplantation development. © 1993 Wiley-Liss, Inc.
