1. Blastocyst

   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 (the portion of the chorion that develops villi) and the underlying uterine tissue of the mother. The name "blastocyst" arises from the Greek βλαστός blastos ("a sprout") and κύστις kystis ("bladder, capsule"). In other animals this is a structure consisting of an undifferentiated ball of cells and is called a blastula. In humans, blastocyst formation begins about five days after fertilization when a fluid-filled cavity opens up in the morula, the early embryonic stage of a ball of 16 cells. The blastocyst has a diameter of about 0.1–0.2 mm and comprises 200–300 cells following rapid cleavage (cell division). About seven days after fertilization, the blastocyst undergoes implantation, embedding into the endometrium of the uterine wall. There it will undergo further developmental processes, including gastrulation. Embedding of the blastocyst into the endometrium requires that it hatches from the zona pellucida, the egg coat that prevents adherence to the fallopian tube as the pre-embryo makes its way to the uterus. The use of blastocysts in in vitro fertilization (IVF) involves culturing a fertilized egg for five days before transferring it into the uterus. It can be a more viable method of fertility treatment than traditional IVF. The inner cell mass of blastocysts is the source of embryonic stem cells, which are broadly applicable in stem cell therapies including cell repair, replacement and regeneration. Assisted zona hatching may also be used in IVF, and other fertility treatments.

1. blastocyst

   A blastocyst is an early stage in the development of mammals, including humans, occurring about five to six days after fertilization of an egg. It is a spherical structure comprised of an outer layer of cells (the trophectoderm), a fluid-filled cavity (the blastocoel), and a cluster of cells (the inner cell mass) which differentiate to form the embryo and eventually an entire organism. This stage usually precedes the implantation into the wall of the uterus.

1. Blastocyst

   The blastocyst is a structure formed in the early gestation of vertebrates. It is preceded by the morula. It possesses an inner cell mass, or embryoblast, which subsequently forms the embryo, and an outer layer of cells, or trophoblast, surrounding the inner cell mass and a fluid-filled cavity known as the blastocoele. The human blastocyst comprises 70-100 cells. Blastocyst formation begins at day 5 after fertilization in humans and is closely related to blastula.

1. Blastocyst

   A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.

Examples of blastocyst in a Sentence

1. Ronald Parchem:

   Anytime you take a species and mix it with another, the host species [the one with the embryo] generally does better, if you take a rat cell and put it into amouse blastocyst[an early embryo], the rat cells are at a disadvantage. Thats why, in general, chimerism is very low.

2. Katie Watson:

   When you have these citizen enforcement statutes, suddenly any random neighbor who says a blastocyst is a [ person ] can sue that clinic, and that's where the chilling is phenomenal.
