What is blastula?

Blastula is an early phase of embryonic development that occurs when the fertilized egg was divided several times, but before its cells distinguished. It consists of approximately 128 cells that form a spherical layer around the central cavity filled with liquid. Another name for Blastula is Blastosphere. The first Zygoty division creates a plague, which is a solid ball of cells. Then blastula is formed when dividing cells or blastomers form a layer called blastoderm surrounding the central cavity or blastocoel. This transition from morura to Blastula is referred to as blastulation. This is followed by a gastrust, which forms another embryonic structure, gastrula. This occurs before the embryo implantation into the uterus. Blastocyst is structured differently than blastula in other animals; It contains a cluster of cells called embryoblast and other outer layer of cells called trophoblast. Later in the development process, these structures will be embryo and placenta. Embryoblast is also a source of embryonic stem cells.

Blastlas of Whitefish offers an ideal opportunity to view cell division or mitosis and are often used to study the process. At this stage, the Whitefish Embrya cells are actively dividing and offering many opportunities to happen. Sometimes they are studied in conjunction with cells of the onion root peaks, which are also rapidly divided to compare mitosis in animals and plants.

6rpose is cloning. Some of the first successful experiments with cloning in the 1950s. The Blastula phase is considered optimal for cloning purposes, as the cells have not yet undergone, which means that they have not developed into any specific cell type. Another advantage of this phase is that there are a large number of cells available due to the number of divisions that occurred at this point. The earlier phases offer undifferentiated cells, but many of them are available.
