Stem cells are the unspecialized cells in the human body that can become specialized cells, with new specialized cell functions. An example of a stem cell is the bone marrow stem cell that is able to turn into specialized blood cells, such as white blood cells and red blood cells. The new cell types have new special functions, that can produce antibodies, combat infection and transport gases. It is called “stem cell” because one function stems from the other. Stem cells have properties of developing into a array of cell types in the body. They can function as a repair system by dividing without a limit to help other cells. When they divide, each cell is able to either become another cell type with new special functions, such as blood …show more content…
Human fetal stem cells can be used by many people including children and adults suffering from many different diseases. An adult stem cell is an undifferentiated cell in a tissue or organ that can renew itself and can differentiate to help the major specialized cell types of the tissue or organ. The job of the adult cell is to maintain and repair the tissue in which they are found. Adult stem cells have been found in many organs and tissues, including brain, bone marrow, peripheral blood, blood vessels, skin, teeth, skeletal muscle, heart, gut, liver, ovarian epithelium, and testis.(National Institutes of Health) In a lot of tissues, evidence shows that some types of stem cells are pericytes, which are cells that compose the outside layer of small blood vessels. Stem cells may remain un-dividing for a long time until they are needed to maintain tissues, by disease or tissue injury. Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. One big difference between adult and embryonic stem cells is their number and type of cells that they can become. Adult stem cells are multipotent
because they are limited to the number of cells they can generate. Embryonic stem cells can generate any cell of the body and therefore they are pluripotent. Embryonic stem cells can be grown easily in
