The blastocyst is a structure formed in the early embryonic development of mammals. It possesses an inner cell mass (ICM) also known as the embryoblast which subsequently forms the embryo, and an outer layer of trophoblast cells called the trophectoderm. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoel. In the late blastocyst the trophectoderm is known as the trophoblast. The trophoblast gives rise to the chorion and amnion, the two fetal membranes that surround the embryo. The placenta derives from the embryonic chorion and the underlying uterine tissue of the mother. The name "blastocyst" arises from the Greek βλαστός blastos and κύστις kystis. In other animals this is a structure consisting of an undifferentiated ball of cells and is called a blastula.

The inner cell mass (ICM) or embryoblast is a structure in the early development of an embryo. It is the mass of cells inside the blastocyst that will eventually give rise to the definitive structures of the fetus. The inner cell mass forms in the earliest stages of embryonic development, before implantation into the endometrium of the uterus. The ICM is entirely surrounded by the single layer of trophoblast cells of the trophectoderm.

Generations was a South African soap opera which first premiered on SABC 1 in 1993. It was created and produced by Mfundi Vundla and aired weekdays at 20:00 UTC+2 on SABC 1. Set against the backdrop of the advertising industry, this drama celebrated the hopes and dreams of South Africans who aspire to a better future.
Acronicta morula, the ochre dagger moth, is a moth of the family Noctuidae. The species was first described by Augustus Radcliffe Grote and Coleman Townsend Robinson in 1868. It is found from Saskatchewan to Nova Scotia, south to Florida, west to Texas.
Cavitation is a process in early embryonic development that follows cleavage. Cavitation is the formation of the blastocoel, a fluid-filled cavity that defines the blastula, or in mammals the blastocyst. After fertilization, cell division of the zygote occurs which results in the formation of a solid ball of cells (blastomeres) called the morula. Further division of cells increases their number in the morula, and the morula differentiates them into two groups. The internal cells become the inner cell mass, and the outer cells become the trophoblast. Before cell differentiation takes place there are two transcription factors, Oct-4 and nanog that are uniformly expressed on all of the cells, but both of these transcription factors are turned off in the trophoblast once it has formed.
