Identify stem cells

Identify stem cells




Indicators of cell factors play an important role in the development of the body of one egg in guiding the many types of body cells, including stem cells that could serve adult tissues, a tine living body that sculpts the body and rebuild.Stem cells specialized cells and incomplete division does not resemble any specialized cell. But able to configure an adult cell after being divided into several divisions, in appropriate circumstances, and the importance of these cells come from being able to configure any type of specialized cells to grow and develop into the desired cells.Thus, stem cells in turn depends on the so-called «embryonic Age» for the body. There are stem cells that generate the ability to make anything. Then there are the stem cells 'overall ability' that you can make more types of tissue, then there are adult stem cells that proliferate to create a special body tissue, such as the liver, bone marrow or skin .. Etc.. Thus, with each step toward adulthood, the successes achieved by the stem cells are narrower, meaning they lead to specialization. In adulthood, do not generate liver cells but other liver cells, skin cells generate other skin cells. However, the signs of recent research suggests that it can manipulate adult cells to return back and enable them to produce various tissues, such as the conversion of bone cells to produce muscle tissue. The embryonic stem cells are found on two forms:First: embryonic stem cells: are obtained embryonic stem cells embryonic stem cells)) pluripotent stem cells from the inner part of the Blastosaat (blastocyte) (which is one of the stages divisions fertilized egg sperm, where the egg is when pollinate sperm cell and one able to configure man full of various members, described as whole cell efficiency (totipotent) divided later this cell several divisions to give the stage known Balblastosaat (blastocyte) consists Albulastolh of an outer layer of cells responsible for the formation placenta and tissues supporting other needed by the fetus during the configuration process in the womb , while the internal cells God creates body tissue different organism). But this can not the Jenin full configuration because it is able to form the placenta and other supporting tissues needed by the fetus during the configuration process, despite the ability of these cells to form any other type of cell within the body. Subject after stem cells for more specialization to make stem cells responsible for the formation of cells with specific functions.
There are stem cells in the tissue already and singled Kalazam and blood etc. ...There are kids and Albagheian alike. These cells are important for the supply of tissue cells that die as a natural result of end-of-life specified in the fabric. Not so far discovered all adult stem cells in all types of tissue. But there are some problems faced by scientists in the use of adult stem cells, and these problems exist in small quantities, which makes it difficult to isolate and its technology, and the number has less robot with age. Moreover, these cells do not have the same ability to reproduce in embryonic stem cells, they may contain some defects as a result of exposure to some psychotropic Calcmom.
