Stem Cells
Stem Cells are an unspecialized type of cell that can change into many different types of cells in early stages of life. In certain tissues these cells act as a type of internal repair system, which divide with almost no limit and repair and replace old or replenish other cells if the person or animal is alive. When stem cells divide they have the chance to become a different type of cell with a more specialized function or stay a stem cell¹. Stem cells are important because they can repair and replace worn out or damaged tissues. Some therapies transplant stem cells to damaged body parts make them grow and differentiate into healthy tissue². Stem cells also now give us potential to treat diseases like diabetes and heart disease¹. …show more content…
At this stage it is known as a blastocyst consisting of two parts inner cell mass and “trophectoderm” outer layer of cells. Some of these cells are pluripotent and can make every type of cell in the body4 . This allows these cells to be used to restore and repair diseased tissue and organs. Their use in people are limited to eye related like macular degeneration6.Adult stem cells are found in infants, children and adults. These cells produce different types of cells for the body’s tissues and organs. Adult stem cells are able to divide are reproduce indefinitely5. The main purpose of adult stem cells in living organisms is to repair and maintain the tissue where they are found1. One major difference between embryonic and adult stem cells is the amount and type of differentiation cell types they can become. Embryonic stem cells are pluripotent which means they can differentiate into any type of cell within the body. Adult stem cells are limited to differentiating in to different types of cells within their certain tissue or organ. Embryonic stem cells can be grown fairly easily in culture while adult stem cells are rare in mature tissue, so it is difficult isolating these cells form adult tissue. Scientists believe that transplanted tissues can differ in the possibility of being rejected if it comes from embryonic or
