Review of Short Phrases and Links

    This Review contains major "Inner Cell Mass"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. The inner cell mass is what becomes the embryo; the outer layer is what forms the fetal side of the placenta.
  2. The inner cell mass is only a millimeter in length after approximately two weeks of development.
  3. This inner cell mass is referred to as the embryoblast, which consists of about 100 cells.
  4. Once the inner cell mass is removed from the blastocyst, the stem cells are placed in a culture dish where they grow and replicate over time.
  5. After the inner cell mass is removed, the blastocyst is no longer capable of further development.

Three Cells

  1. Therefore, it appears that three cells make the inner cell mass of the compacted embryo.

Cells Surrounding

  1. In contrast to embryonic stem cells, the trophoblast does not come from the inner cell mass, but from cells surrounding it.

Syncytiotrophoblast

  1. While the syncytiotrophoblast starts to penetrate into the wall of the uterus, the inner cell mass (embryoblast) also develops.

Trophectoderm

  1. Role of Cdx2 and cell polarity in cell allocation and specification of trophectoderm and inner cell mass in the mouse embryo.

Outer Cell Mass

  1. It possesses an inner cell mass, or embryoblast, and an outer cell mass, or trophoblast.
  2. Blastocyst formation begins on day 5 post- egg retrieval and is defined by the presence of an inner cell mass and the outer cell mass or trophectoderm.

Single

  1. The blastocyst can be thought of as a ball of a (mostly single) layer of trophoblast cells, with inner cell mass attached to this ball's inner wall.

Mammals

  1. Mammals at this stage form a structure called the blastocyst,[4] characterized by an inner cell mass that is distinct from the surrounding blastula.

Implantation

  1. As the blastocyst completes implantation during the second week, the inner cell mass undergoes marked differentiation.

Rise

  1. The upper layer of a group of cells derived from the inner cell mass of the blastocyst; it gives rise to all cells of the fetus.
  2. Inner Cell Mass: The cluster of cells found inside the blastocyst that gives rise to all the cells of the body in the developing human organism.
  3. The cells of the inner cell mass can give rise to progeny differentiating into all the types of cells in the adult body, so they are called pluripotent.

Layers

  1. The inner cell mass of the blastocyst divides rapidly, forming two layers.

Three Germ Layers

  1. Epiblast Cells: From inner cell mass, will ultimately give rise to the three germ layers and the entire embryo.

Stem Cell

  1. A stem cell that is derived from the inner cell mass of a blastocyst and can differentiate into several tissue types in a dish.

Type

  1. Human embryonic stem cell A type of pluripotent stem cell derived from the inner cell mass of the blastocyst.

Embryonic Stem Cells

  1. Cells taken from the inner cell mass of the blastocyst (a very early stage embryo) can become embryonic stem cells.
  2. Embryonic stem cells are made by isolating and culturing the cells that make up the inner cell mass.
  3. Also called ES cells, embryonic stem cells are cells derived from the inner cell mass of developing blastocysts.

Mesoderm

  1. Mesoderm Middle layer of a group of cells derived from the inner cell mass of the blastocyst; it gives rise to bone, muscle, and connective tissue.

Icm

  1. Human embryonic stem cell (hESC) -A type of pluripotent stem cell derived from the inner cell mass (ICM) of the blastocyst.
  2. Inner cell mass (ICM) -The cluster of cells inside the blastocyst.

Embryoblast

  1. The blastocyst consists of cells forming an outer trophoblast layer, an inner cell mass (embryoblast) and a fluid-filled cavity.
  2. The inner cell mass gives rise to the embryo proper, and is therefore, called the Embryoblast.
  3. Inside the blastocyst is an inner cell mass or embryoblast (future embryo), and the outer cell mass or trophoectoderm (future placenta).

Ectoderm

  1. Ectoderm Upper, outermost layer of a group of cells derived from the inner cell mass of the blastocyst; it gives rise to skin nerves and brain.

Outer

  1. There are two layers at this stage, the outer layer or trophoblast and the inner cell mass.

Human Body

  1. The cells of the inner cell mass go on to form virtually all of the tissues of the human body.

Form

  1. Embryonic stem cells are derived from the inner cell mass of blastocysts, which are hollow balls of cells that form in early development.
  2. The embryo proper begins to form from an inner cell mass within the blastocyst.
  3. A portion of cytotrophoblast cells (near the inner cell mass) form the highly invasive syncytiotrophoblast which penetrates into the endometrial stroma.

Placenta

  1. The inner cell mass forms the embryo, while the outer cell layers form the membranes and placenta.

Germ Layers

  1. Highlights (continue) Embryonic disc = • the cells of the inner cell mass multiply, and arranged to form an embryonic disc having two germ layers.

Endoderm

  1. The inner cell mass undergoes changes to form three germ layers known as the ectoderm, the mesoderm, and the endoderm.
  2. Endoderm Lower layer of a group of cells derived from the inner cell mass of the blastocyst; it gives rise to lungs and digestive organs.

Endometrium

  1. The blastocyst becomes oriented with the inner cell mass toward the endometrium.

Embryos

  1. Conversely, embryos in which Oct-4 expression is knocked out fail to maintain pluripotency within the inner cell mass (6).

Embryo

  1. The inner cell mass of the blastocyst will go on to form the embryo.
  2. The cells from the inner cell mass have the potential to develop into an embryo, then later the fetus, and eventually the entire body of the adult organism.
  3. The inner cell mass below the amniotic cavity flattens into an embryonic disc that will form the embryo.

Cells

  1. Although the inner cell mass cells can form virtually every type of cell found in the human body, they cannot form an organism.
  2. The inner cell mass cells will go on to form virtually all of the tissues of the human body.
  3. Although the cells of the inner cell mass can form virtually every type of cell found in the human body, they cannot form an organism.

Epiblast

  1. As the outer cell mass invades the endometrium, the inner cell mass divides into two layers: the epiblast and hypoblast.
  2. At the time of implantation, the inner cell mass forms a flat disk with an upper layer of cells, the epiblast, and a lower layer, the hypoblast.

Trophoblast

  1. The blastocyst consists of two primary cell lines: the inner cell mass, also known as the epiblast, and the trophoblast.
  2. Early in mammalian development, the conceptus differentiates into an inner cell mass and an outer sphere of cells, the trophoblast.
  3. The inner blastomeres will become the inner cell mass and the blastomeres on the surface will later flatten to form the trophoblast.

Blastocyst

  1. Pluripotency is a property of the inner cell mass (ICM), from which mouse ES cells are derived, and of the epiblast of the blastocyst.
  2. This then changes to a blastocyst, consisting of an outer layer called a trophoblast, and an inner cell mass called the embryoblast.
  3. The blastocyst has an outer layer of cells and inside the hollow sphere, there is a cluster of cells called the inner cell mass.

Inner Cell Mass

  1. The inner cell mass gives rise to the embryo proper, the amnion, yolk sac and allantois, while the trophoblast will eventually form the placenta.
  2. The blastocyst is characterized by a group of cells, called the inner cell mass (also called embryoblast) and the mentioned trophoblast (the outer cells).
  3. The tissues of the embryo are all derived from the inner cell mass as are the amnion and major components of the yolk sac and allantois.
