cluster of cells within the blastocyst from which HES cells are derived
Cells of the blastocyst that will form the body of the embryo.
The cluster of cells inside the blastocyst. Before implantation, these can give rise to embryonic stem cell lines. After implantation, the inner cell mass gives rise to all the tissues of the fetus, as well as some of the membranes around it.
Group of cells in a blastocyst which develop into the embryo
Within a blastocyst - the hollow ball of cells that forms soon after an egg is fertilised - there is a mass of cells on one side which will form the body of the embryo. This is referred to as the inner cell mass. This is where embryonic stem cells are taken from.
The area of cells inside a blastocyst that will go on to form the developing foetus
The cells in the blastocyst that develop into the embryo. 218
a group of cells found inside a blastocyst and from which embryonic stem cells are derived
The cluster of cells inside the blastocyst. Embryonic stem cells are derived by isolating and culturing the cells that make up the inner cell mass.
Group of centrally located blastomeres, thin outer layers of cells
Cluster of stem cells inside the blastocyst. These cells are completely blank and can grow into all cells in the body.
the clump of cells found inside the blastocyst. These cells will go in to form the embryo, these are the "stem cells" (we here about in the media) that are totipotential, they can form any tissue in the embryo. Mature oocyte-the female germ cell released at ovulation from the ovary.
The cluster of cells inside the blastocyst. These cells give rise to the embryonic disk of the later embryo and, ultimately, the fetus.
A cluster of cells in the blastocyst from which embryonic stem cell lines can be isolated and grown in culture.
A cluster of cells inside a blastocyst from which embryonic stem cells are derived. In a developing embryo, the inner cell mass gives rise to all of the organs and tissue of the future embryo and foetus.
A small group of cells attached to the wall of the blastocyst (the embryo at a very early stage of development that looks like a hollow ball). embryonic stem cells are made by isolating and culturing the cells that make up the inner cell mass. In development, it is the inner cell mass that will eventually give rise to all the organs and tissues of the future embryo and fetus, but do not give rise to the extra-embryonic tissues, such as the placenta.
Group of cells that differentiates within (but to one side of) the developing embryo when it is a blastocyst and which will, if all goes well after implantation, form the embryo-proper, or fetus. Cells from the inner cell mass can be used to produce embryonic stem cell See also: trophectoderm
A group of cells found in the blastocyst that give rise to all the tissues of the embryo.
The centrally located cells within the blastocyst; these cells will develop into the embryo.
In early embryogenesis, the inner cell mass (abbreviated ICM and also known as the embryoblast) is the mass of cells inside the primordial embryo that will eventually give rise to the definitive structures of the fetus. This structure forms in the earliest steps of development, before implantation into the endometrium of the uterus has occurred. The ICM lies within the blastocoele and is entirely surrounded by the single layer of cells called trophoblast.
