In a society where faster means better and technology has rapidly taken control of people's lives, the means of human health have changed. Advances in medical research have led to the use of existing cells in humans' bodies and placentas to heal serious injuries that typically take years to fully return to normal (Boniello). The cells are commonly called stem cells and can transform into different cell types depending on the injury, location, and the body's needs. Scientists realize the importance of stem cells and the power they possess: “At first, one cell becomes two, and two becomes four. Being fertile, they multiply into a ball of many cells, a glittering sphere of human potential” (Weiss). The extraction of these cells, however, generates much controversy from religious groups. Indeed, the stem cells that scientists prefer to use for better results come from human embryos and placentas. Experts in stem cell research may use different methods to acquire stem cells, but all agree that how the world decides on the use of embryonic stem cells will say a lot about our character and what will become of us. the human race (Weiss). Ralph Fariello, director of Cedar Knolls, says, “Researchers can obtain 10 times more stem cells by processing a placenta than by simply taking blood from the umbilical cord” (Boniello). Although stem cells derived from embryos, placentas and umbilical cords are very difficult to obtain, adult stem cells are just as useful. Stem cell research is a major breakthrough in medical history because it repairs the human body with existing cells, a quick recovery time and can lead to new discoveries.
