Stem Cell Research Essay -- Science Biology Stem Cells Essays Papers

Stem Cell Research Research on stem cells is advancing knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. This promising area of science is also leading scientists to investigate the possibility of cell-based therapies to treat disease, which is often referred to as regenerative or reparative medicine. Research on the topic of stem cells is advancing the scientific knowledge about how cells develop. Stem cell research is applied to two main characteristics that allow stem cells to be distinguished among most other types of cells. The first major characteristic is that the stem cells are unspecialized and can renew themselves through cell divisions for longer durations of time. Secondly, the cells can be manipulated under certain conditions to become any cell that the scientist encodes them with; liver cell or even a heart cell. Scientists primarily work with two types of stem cells; embryonic and adult, descriptions will be addressed later. Unlike muscle cells, blood cells, and nerve cells, stem cells may replicate many times. An initial population of stem cells grows for many months and in lab conditions can produce millions of cells. The cells are termed to be long term self renewing if the produced cells are unspecialized like their parent stem cells. A key topic in stem cell research is called differentiation. Differentiation is described as being when unspecialized cells give rise to new specialized cells. Scientists are still exploring this topic and what signals this action. So far they have described the external signal. The external signal is when chemical secretions are passed on by other cells, physical contact is made, and c... ...ce this new technology, maybe not for decades but this new science will effect our immediate future. The line has to be establishing that separates moral and ethical uses from inhuman and un-ethical uses. That line was not a major focus before February 12, 2004, now people in the science field have a major task at hand. In conclusion human embryonic and adult stem cells each have advantages and disadvantages for future application. Embryonic stem cells can differ in number and type of differentiated cells they can become. Adult stem cells are generally limited to differentiating into different cell types of their specific tissue or organ of origin. Stem cell research will be able to be used to test drugs and their effects, along with their most important application of human stem cells to regenerate tissues that could be used for cellular based functions.
