Analysis of cell lineage in two- and four-cell mouse embryos.
Compared with other animals, the embryos of mammals are considered to have a highly regulative mode of development. However, recent studies have provided a strong correlation between the first cleavage plane and the future axis of the blastocyst, but it is still unclear how the early axes of the preimplantation embryo reflect the future body axes that emerge after implantation. We have carried ...
متن کاملI-13: Transcriptome Dynamics of Human and Mouse Preimplantation Embryos Revealed by Single Cell RNA-Sequencing
Background: Mammalian preimplantation development is a complex process involving dramatic changes in the transcriptional architecture. However, it is still unclear about the crucial transcriptional network and key hub genes that regulate the proceeding of preimplantation embryos. Materials and Methods: Through single-cell RNAsequencing (RNA-seq) of both human and mouse preimplantation embryos, ...
متن کاملI-19: Surrogate Egg Shell Culture for The Analysis of Avian Stem Cell Fate
Background: The chick embryo is a classical model to study embryonic development. However, most researchers have not studied the effect of embryonic manipulation on chick hatchability. To determine the effect of egg orientation and type of sealing film on the hatchability of cultured embryos, and to determine the fate of adulte stem cells injected into the blastoderm. Materials and Methods: Win...
متن کاملCdx2 gene expression and trophectoderm lineage specification in mouse embryos.
Controversy exists as to whether individual blastomeres from two-cell-stage mouse embryos have identical developmental properties and fate. We show that the transcription factor Cdx2 is expressed in the nuclei of cells derived from the late-dividing but not the first-dividing blastomere of two-cell embryos and, by lineage tracing and RNA interference knock-down experiments, that this lagging ce...
متن کاملBlastomere explants to test for cell fate commitment during embryonic development.
Fate maps, constructed from lineage tracing all of the cells of an embryo, reveal which tissues descend from each cell of the embryo. Although fate maps are very useful for identifying the precursors of an organ and for elucidating the developmental path by which the descendant cells populate that organ in the normal embryo, they do not illustrate the full developmental potential of a precursor...
