It has been on the news lately. A patient paralyse by a spinal cord injury in the United States of America, has been treated using a therapy made from embryonal stem cells (this event took place at Atlanta on the 12th of October, 2010 ). The uses and isolation of embryonic stem cells have been debated for a while now; on that pointfore, this makes the event that took place above a celebrated one because it shows a positive and critical stones throw in the treatment of diseases. Although, adult stem cells have been apply in the past to treat Alzheimer, Stroke, Parkinsons disease, diabetes, to mention a few, little or nothing is known by the mass of the public about the type of stem cells, where they arise from or the vast lasts they can perform.
Stem cells are simply un differentiate cells and by undifferentiated, I mean cells that have no function yet. To cite Cooper (2007), stem cells were first identified in hematopoietic system in 1961 by Ernest Mcculloch and James work on in an experiment showing that single cells from mouse osseous tissue marrow could proliferate and give rise to multiple differentiated types of blood cells. Stem cells are unspecialized cells in embryos that last develop into many different specialized cells.
According to Campbell (2002), cell division, cell preeminence and morphogenesis are the three interrelated abut from which an electric organism arise, therefore, we can see from this statement that cell differentiation is an important step for the growth of an organism. Cell differentiation is a process by which a cell becomes specialized.
Potency is a word usually associated with stem cells, and this means the force of a stem cell to differentiate. As the National Academy of Sciences (2002) reports, there are basically three types of potency; totipotency, pluripotency and multipotency. Totipotency is the ability of a stem cell to differentiate into anything from a tissue, to an organ and even to a complete organism. Pluripotency is...If you want to get a full essay, order it on our website: Ordercustompaper.com
