Biology and Stem Cells - Article ExampleThe embryonic stem cells (ESC) so-and-so be described as pluripotent which means that the cells can form any type of specialized cell. In addition, ESC can be considered as more widespread and ubiquitous as comp atomic number 18d to the nonembryonic stem cells (non-ESC). The main credit of ESC is the inner cell mass of blastocyst which is formed within a few days of the fertilization of egg which will develop into the fetus.The use and importance of the ESC had been recognized and thus the ESC line had been established in 1998 from an embryo. These ESC lines argon created to be able to provide sources for the extraction of undifferentiated cells for application in the medical field. asunder from the extraction of ESC from embryos, there is an alternative manner of producing such cells. In the process known as the thermonuclear transfer or therapeutic cloning, the nonphysiological ESC lines are produced.The nonembryonic stem cells, also ref erred to as non-ESC, are multipotent collect to the restricted function in terms of differentiation and development into specialized cell types. The main sources of non-ESC are adults, specifically, the bone marrow thus referred to as the adult stem cells. The non-ESC can be classified as hemopoietic and mesenchymal stem cells. Hemopoietic stem cells can develop into the different types of blood cells. The mesenchymal stem cells are less differentiated compared to the other type. In addition to bone marrow sources, other sources are nose, muscle, liver, skin, brain, and mall (esp. retina and limbus). It is important to consider that although from adult source, stem cells are derived from comparatively less developed tissue sources.
