Stem Cell Research: Boon or Bane? One of the fast developing technologies in medicine is the stem cell research. Stem cells have the ability to develop into different type of cells in the body in the early life and growth of it. These special cells essentially divide themselves with no limit in order to replenish other cells as long as the organism is still alive. Therefore, stem cells are responsible for the internal repair system of the body. When the cell division continues, the newly divided cells have two options, either remain being a stem cell or divide further to become another type of cell with specialized function. Therefore, stem cell can supply the needed cell of the body such as muscle cell, brain cell, a neuron or a red blood cell (Bethesda, 2015). There are three special characteristics of the stem cells that excessively discriminate them from other cells. One is they are unspecialized cells that is capable of renewing themselves through repeated cell division. Unlike muscle cells, stem cells can replicate or proliferate itself many times. This process can yield millions of copies of stem cells after many months in the laboratory. Also, if the resulting cells continuously divide themselves and are all unspecialized- these cells are said to be capable of long-term self-renewal. They also can divide themselves regardless of long periods of inactivity (Bethesda, 2015). Secondly, stem cells are all unspecialized. The most stunning characteristic of stem cell is that they don’t have any tissue- specific structures that allow it to perform specialized functions. For example, a stem cell cannot perform the work of its neighbor cells like the muscle cells, it cannot pump blood through the body, and the red blood cells, it cannot supply oxygen to the tissues. However, they can be any specialized cell under physiological conditions (Bethesda, 2015). Lastly, under experimental conditions, stem cells can be forced to form tissue- or organ-specific cells with specialized functions. This process is called differentiation.

stage of the differentiation process. Scientist studies the internal and external signal that triggers the cell to differentiate (Bethesda, 2015). The internal signals are controlled by the genes of the organism. Genes are interspersed long strands of DNA that carry coded instructions for all

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
