Blastocysts: 10 things IVF patients should know
2024年4月26日 · What is a blastocyst? A blastocyst is a human embryo that’s five or six days old. Ten years ago, day-three embryos were routinely transferred in IVF cycles. Most clinics now believe that transferring better-developed embryos – i.e. those that have reached the blastocyst stage – makes an ongoing pregnancy more likely. 2.
Blastocyst - Wikipedia
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.

Blastocyst Development - Embryology
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.
