Dictionary » B » Blastocyst



in mammalian development, cleavage produces a thin walled hollow sphere, whose wall is the trophoblast, with the embryo proper being represented by a mass of cells at one side. The blastocyst is formed before implantation and is equivalent to the blastula.

What is ES Cell Based Gene Overexpression?

... form of Embryonic stem cell. As far as I know, ES Cells are usually pluripotent stem cells. They are derived from the inner cell mass of a blastocyst. ES Cells have the ability to differentiate into any cell type and by their ability to propagate. Therefore, ES cell based overgene expression ...

An Overview of Embryonic Stem Cells

... a major breakthrough for developmental biology in the history. And later scientists were wondering that if ES cells could be derived from human blastocysts, their capacity for multilineage differentiation might be exploited for cell-based therapies in which virtually any tissue or cell type ...

Stem Cells and Cell division?

... The blastomeres stick together to form a tight ball of cells called a morula. Each of these cells retains totipotential. The next stage is the blastocyst which consists of a hollow ball of cells; trophoblast cells along the periphery develop into the embryonic membranes and placenta while the ...

Delayed Implantation

I believe the blastocyst remains floating in the uterus until the necessary physiological changes occur that promote the attachment of the blastocyst to the uterine wall

which mechanism triggers the first cell differentiation?

... days after fertilization and after several cycles of cell division, these cells begin to specialize, forming a hollow sphere of cells, called a blastocyst but do not explain why they begin to specialize. I could imagine ⋅ that a cell has a "counter" on the number of divisions ...
