Diagram Of A Blastocyst

The blastocyst is a structure formed in the early development of mammals.It possesses an inner cell mass (ICM) which subsequently forms the embryo.The outer layer of the blastocyst consists of cells collectively called the trophoblast.This layer surrounds the inner cell mass and a fluid filled cavity known as the blastocoel.The trophoblast gives rise to the placenta.

Blastocyst, a distinctive stage of a mammalian embryo. It is a form of blastula that develops from a berrylike cluster of cells, the morula. A cavity appears in the morula between the cells of the inner cell mass and the enveloping layer. This cavity becomes filled with fluid. The blastocyst

The blastocyst consists of cells forming an outer trophectoderm (TE, trophoblast) layer, an inner cell mass (ICM, embryo blast) and a blastocoel (fluid filled cavity). The inner cell mass will form the entire embryo, and is the source of true embryonic stem cells capable of forming all cell types within the embryo.

The stages of blastocyst embryo development are divided into four grades. Grade 1: The embryo with a blastocoel cavity less than 50% of the embryo volume. Grade 2: The embryo with a blastocoel cavity as much as 50% of the embryo volume or more. Grade 3: Embryo that has a blastocoel cavity which has fulfilled that all embryos and zona pellucida (ZP) appeared to be thinner than embryo on day 3.

Blastocyst (day 4) (inner cell mass (embryoblast) (day 7), trophoblast (day 7), Morula ), further development, formation of chorionic villi, gastrulation invagination(insertion of epiblast) (day 15 16), , embryo development, Neurulation (week 4), without BMP4, without BMP4, epithelial to messenchymal transition, Fate map determination (at gastrulation), implantation (day7 11) trophinin and ...

A diagram showing the ovarian cycle, fertilization, and the events of the first week following fertilization. Implantation of the blastocyst begins between the fifth and seventh day and is generally complete by the tenth day.

Definition of a blastocyst: An embryo which has developed to the point of having 2 different cell components and a fluid cavity; Human embryos from in vitro fertilization in culture in an IVF lab, or developing naturally in the body, usually reach blastocyst stage by day 5 after fertilization; Blastocyst transfer with IVF can give high pregnancy success rates with very low risk of triplets
