blastocyst etymology

Etymology

• Blasto- from Greek blastos, meaning "germ, bud"
• -cyst from Greek kystis, meaning "bladder, sac"

Meaning

A blastocyst is an early stage of embryonic development in mammals, consisting of a hollow ball of cells with an inner cell mass (which will form the embryo) and a surrounding trophoblast layer (which will form the placenta).

Origin

The term "blastocyst" was first used in 1870 by German embryologist Robert Remak to describe the early embryonic stage in rabbits. However, the concept of the blastocyst was not fully understood until the early 20th century, when advancements in microscopy and cell culture techniques allowed researchers to observe and study the development of mammalian embryos in detail. Today, the blastocyst is recognized as a critical stage in mammalian development, representing the transition from the early cleavage stages to the more advanced stages of gastrulation and organogenesis.
