Gene expression during preimplantation mouse development.
To develop a resource for the identification and isolation of genes expressed in the early mammalian embryo, large and representative cDNA libraries were constructed from unfertilized eggs, and two-cell, eight-cell, and blastocyst-stage mouse embryos. Using these libraries, we now report the first stages at which the cytokines interleukin (IL)-6, IL-1 beta, and interferon (IFN)-gamma are transc...
متن کاملChanges in the distribution of a spectrin-like protein during development of the preimplantation mouse embryo
The mouse blastocyst expresses a 240,000-mol-wt polypeptide that cross-reacts with antibody to avian erythrocyte alpha-spectrin. Immunofluorescence localization showed striking changes in the distribution of the putative embryonic spectrin during preimplantation and early postimplantation development. There was no detectable spectrin in either the unfertilized or fertilized egg. The first posit...
متن کاملThe Evaluation of Melatonin Effect on In-Vitro Development of Mouse Preimplantation Embryos
Purpose: Melatonin promotes in-vitro embryo development in different species. This study studied the effects of melatonin on in-vitro mouse preimplantation embryo development. Materials and Methods: Two-cell embryos were obtained from oviduct of 6-8 weeks female NMRI mice 48 hours after administration of an intra-peritoneal injection of 5 IU/ml pregnant mares’ serum gonadotrophin and subsequent...
متن کاملThe expression and stage-specific localization of protein kinase C isotypes during mouse preimplantation development.
Signaling events mediate many processes that act during embryogenesis to initiate the program of early development. Within the cell many of these changes are mediated through the activation or inactivation of kinases and phosphatases. Protein kinase C (PKC) is one kinase that has been shown to be involved in at least two developmental transitions during early development, fertilization and embr...
متن کاملThe Effect of Human Follicular Fluid (FF) on Preimplantation Mouse Embryo Development in Vitro
SUMMARY Since at oocyte retrieval for in vitro fertilization there is some FF become incorporate to egg, we decided to investigate the effect of this fluid on preimplantation embryo development in vitro. FF was obtained at the time of oocyte retrieval for IVF, centrifuged and then either inactivated by heat and stored at 4°c or without inactivation stored at-20°c until used. Late 2-cell emb...
