Expression profile of developmentally important genes in pre- and peri-implantation goat embryos produced in vitro
Background Little is understood about the regulation of gene expression during early goat embryo development. This study investigated the expression profile of 19 genes, known to be critical for early embryo development in mouse and human, at five different stages of goat in vitro embryo development (oocyte, 8-16 cell, morula, day-7 blastocyst, and day 14 blastocyst). MaterialsAndMethods Stage-...
متن کاملStem cell defects in parthenogenetic peri-implantation embryos.
Mouse embryos containing only maternal chromosomes (parthenotes) develop abnormally in vivo, usually failing at the peri-implantation stage. We have analyzed the development of parthenote embryos by using an inner cell mass (ICM) outgrowth assay that mimics peri-implantation development. ICMs from normal embryos maintained undifferentiated stem cells positive for stage-specific embryonic antige...
متن کاملImprinted Gene mRNA Expression during Porcine Peri-implantation Development*
Imprinted genes are essential for fetal development, growth regulation, and postnatal behavior. However, little is known about imprinted genes in livestock. We hypothesized that certain putatively imprinted genes affected normal peri-implantation development such as embryo elongation, initial placental development, and preparation of implantation. The objective of the present study was to inves...
متن کاملRegulation of cyp26a1 on Th17 cells in mouse peri-implantation
Cytochrome P450 26A1 (cyp26a1) is expressed in the mouse uterus during peri-implantation. The repression of this protein is closely associated with a reduction in implantation sites, suggesting a specific role for cyp26a1 in pregnancy and prompting questions concerning how a metabolic enzyme can generate this distinct outcome. To explore the effective downstream targets of cyp26a1 and confirm i...

1596 www.thelancet.com Vol 374 November 7, 2009 direct engagement with countries, and weak design and assessment mechanisms. GAVI relies on in-country WHO and UNICEF staff , both better versed in immunisation than in health systems, and the Global Fund relies on country coordinating mechanisms whose members have disease-specifi c interests, mostly HIV. Both use panels in Geneva—the Independent ...
