P-126: Stem Cell Factor Increases Blastocyst Formation in Mouse Two-Cell Embryo Culture
Background: It is demonstrated that c-Kit( receptor of stem cell factor) mRNA is expressed in late 2-cell stage to the expanded and hatched blastocyst and the stem cell factor (SCF) transcript is detected in the oviduct and uterus. The aim of this study was to investigate the effect of different doses of SCF on mouse 2-cell embryo development in vitro. Materials and Methods: 4-6 weeks old femal...
متن کاملErythrocytes counteract the negative effects of female ageing on mouse preimplantation embryo development and blastocyst formation.
BACKGROUND The low developmental competence of embryos from ageing females remains an enigma; it is presumably attributable to oxidative stress. A number of antioxidant mechanisms exist in the erythrocyte and these have been investigated in other cells and tissues. However, very few studies have reported the effects of erythrocyte supplementation on developmental competence in ageing embryos. ...
متن کاملWdr74 Is Required for Blastocyst Formation in the Mouse
Preimplantation is a dynamic developmental period during which a combination of maternal and zygotic factors program the early embryo resulting in lineage specification and implantation. A reverse genetic RNAi screen in mouse embryos identified the WD Repeat Domain 74 gene (Wdr74) as being required for these critical first steps of mammalian development. Knockdown of Wdr74 results in embryos th...
متن کاملA maternal factor affecting mouse blastocyst formation.
Normal development of the mouse embryo requires the presence of both paternal and maternal genomes. This is due to functional differences having their origin in a differential imprinting of parental genomes. Furthermore, several lines of evidence show that the very early interactions between egg cytoplasm and pronuclei may influence the programming of the embryonic genome and modulate the funct...
متن کاملFormation of distinct cell types in the mouse blastocyst.
Early development of the mouse comprises a sequence of cell fate decisions in which cells are guided along a pathway of restricted potential and increasing specialisation. The first choice faced by cells of the embryo is whether to become trophectoderm (TE) or inner cell mass (ICM); TE is an extra-embryonic tissue which will form the embryonic portion of the placenta, whilst ICM gives rise to c...
