Stems common form of dementia and is caused

Published by admin on

Stems cells are a type of undifferentiated cells biological cells that can differentiate into specialized cells.During initial phases of development, all cells of the morula are totipotent but the cells begin to lose their totipotency and differentiate distributing into groups that will either become the placenta or the embryo.The inner cell mass of the blastocyst (which is a hollow ball formed after many rounds of division of the morula) has the capability to bring about to all of the bodies many cell types this is known as pluripotency all the cells in the body can trace their ancestry back to these cells.Stem cells are located in different areas e.g. 1. embryonic stem cells from the blastocyst 2. intestinal glands of the small intestine known as crypts near their bases. they maintain their own number but and the same time producing rapidly dividing progeny.3. the bone marrow which contains hemopoietic stem cells and stromal stem cells.Alzheimer’s is a degenerative brain disorder, it’s a common form of dementia and is caused by loss of neurons in the brain. When a person is diagnosed with Alzheimer’s their nervous system regenerates too poorly to restore itself after injury or in this case brain cell death. Ideally, this is where stem cells would come in since they are able to divide and make copies of themselves indefinitely (aka self-renewal) but their division is not limited to creating more stem cells but can produce other mature cells like nerve cells.Embryonic stem cells are harvested from the blastocyst since these ESC’s exhibit pluripotency thus stem cell research poses a moral quandary as you are ‘BASICALLY DESTROYING HUMAN LIFE TO SAVE HUMAN LIFE’ or are you? What is the moral status of the early human embryo? Is it already a soul or is it a mass of inanimate cells like a plant? The main question is when does life begin? and if the early human embryo has begun life do we now say they are not deserving of protection like the basic right RIGHT TO LIFE. For some people, the early embryo has no status and it is a matter of moral obligation that research should be carried out to cure disease and end suffering which justifies killing what will essentially become a human being. The same people argue that the fertilized embryo can become one, two, three, or even more babies but there is a much higher possibility of it becoming nothing and instead of allowing this mass of cells to go to waste it can be harvested for the good of mankind.Other people argue that from a religious standpoint the scientist has no right to play God simply for the sake of medicine, they say all life should be protected at all cost and once you start making exceptions the lines will become blurred. The objective in mind may be good but is it ethical, moral or right? Which set of spectacles do you wear the staunchly pro-life where your opinion cannot be swayed or the one where you believe society can be saved but at a very heavy cost. The cost of life.Due to an aging population worldwide, Alzheimer’s disease is getting increasingly popular and successful use of stem cells to cure it would mean other diseases would be cured and the funds could be allocated to something else as Alzheimer’s is a costly disease to care for.
