WebCleavage refers to the stereotyped pattern of early mitotic divisions that divides up the large volume egg cytoplasm. The early zygote is unique in being so large. Most cells undergo a period of growth between cycles of mitosis, but this is not true for early cleavage stage blastomeres. With each division the cells get smaller. WebBlastulation is the stage in early animal embryonic development that produces the blastula. In mammalian development the blastula develops into the blastocyst with a differentiated inner cell mass and an outer trophectoderm. The blastula (from Greek βλαστός ( blastos meaning sprout )) is a hollow sphere of cells known as blastomeres ...

WebSince the goal of development is the production of a multicellular organism, many cells must be produced from the single-celled zygote. This task is accomplished by cleavage, a series of consecutive cell divisions. Cells produced during cleavage are called blastomeres. The divisions are mitotic — i.e., each chromosome in the nucleus splits ... http://www.vivo.colostate.edu/hbooks/pathphys/reprod/fert/cleavage.html WebThe main functions of adult stem cells are to replace cells that are at risk of possibly dying as a result of disease or injury and to maintain a state of homeostasis within the cell. [2] There are three main methods to determine if the adult stem cell is capable of becoming a specialized cell. [2] patchwork skabeloner
