At this point in its development, it has about 200-400 cells and is made up of two well-differentiated parts: Internal cell mass cells that will give rise to the embryo itself. Trophoectoderm are the outermost cells that will form the placenta and other embryonic attachments. Additionally, ...
From day 3 to day 5, embryos grow to form a blastocyst which is made up of two distinct types of cell: foetal cells (also called the inner cell mass or ICM) and placental cells (also called trophectoderm or TE). The placental cells form the outer layer of the embryo, surrounding the ...
a model organism that develops rapidly, exhibits extensive cell type diversity and is made up of a relatively small number of cells. The ‘zebrafish single-cell atlas of perturbed embryos’ (ZSCAPE) constitutes two major efforts: (1) the establishment of an annotated, individually resolved referen...
Finally, using whole embryo single-cell RNA count data, we propose two alternative single-cell variability measures to the commonly used Fano factor, and compare the capacity of these three measures to address different aspects of single-cell expression variability....
Here, we describe the application of these three technologies to zebrafish, a model organism that develops rapidly, exhibits extensive cell type diversity and is made up of a relatively small number of cells. The ‘zebrafish single-cell atlas of perturbed embryos’ (ZSCAPE) constitutes two major...
Mouse Early Embryo Development Mouse Early Embryo Development Embryonic development is the generation of a multicellular organism from a single cell. During this process, tissues and organs are differentiated and positioned at different parts of the organism. In animals, Embryonic development consists of ...
The addition of cells is achieved by microinjection of single cells or groups of cells using micropipets. Large fragments can also be transplanted by grafting parts of an embryo to defined regions of another embryo. In both cases, the cells or tissues are procured from the donor embryo and ...
The truth is, 44 is a complicated age to get pregnant. As you may know, the ovarian reserve keeps on diminishing over time, and by age 44 women not only have fewer changes of getting pregnant, but also the eggs they are able to produce present a poorer quality, which means they are ...
As it turns out, the zygote stage is over even faster than that precious newborn stage—your future little one will only be a zygote for a matter of days. But developmentally speaking, those were crucial days: even though it only contains a single cell, the zygote has all of the genetic...
Coordinated directional migration of cells in the mesoderm layer of the early embryo is essential for organization of the body plan. Here we show that mesoderm organization in mouse embryos depends on β-Pix (Arhgef7), a guanine nucleotide exchange facto
