Stem Cell Research : The Era Of Life Science Essay

Good Essays
Twenty-first century is the era of life science. With the development of technology of life science and modern biology, the stem cell research becomes one of the most advanced research areas in the current society. Stem cells have regenerative possibilities; Nadia Rosenthal wrote in The New England Journal of Medicine: We mere mortals do not possess livers with quite so vigorous a regenerative capacity, but the legend captures well the remarkable potential of the body to rebuild itself. Throughout our lives we sustain less gruesome injuries from which we recover spontaneously, often without realizing we were hurt. Wound healing involves the recruitment and proliferation of cells capable of restoring tissues and even organs to their original form and function. These cells must retain a collective memory of the complex developmental process by which the tissue was first constructed.
Most stem cells have limited potential to form only certain differentiated progeny cells. The only certain exception is the embryonic stem cell, which refers to the original cells not split up and has the potentialities of renewing, proliferating and breaking up themselves into a variety of tissues and organs. Embryonic stem cells are therefore pluripotent “because it builds entire bodies—for mammals, in a matter of months.” (Furcht 39) Furthermore, human embryonic stem cells can grow continuously in laboratory conditions for over two years without losing their ability to self-renew or to form
