Gripped in controversy, the United States of America had grappled with whether or not to study embryonic stem cells and clone human tissues since they were discovered. Stem cells, according to the National Institutes of Health, are unspecialized cells with remarkable potential for developing into a variety of organic structures (Stem Cell Basics: Introduction). These biological components were first discovered in human umbilical cord blood in 1978, and in 1981, they were first successfully developed from mice blastocysts conceived through in vitro fertilization (Murnaghan). As research into these cells increased, the cell biologist James Thomson “isolated cells from the inner cell mass of early embryos” (Murnaghan), leading to the creation of the first human embryonic stem cells.
Stem cells have many aspects; however, the most salient – and controversial – attribute of stem cells is their ability to “be induced to become tissue- or organ-specific cells with special functions” (Stem Cell Basics: Introduction). After several years of study, scientists and researchers discovered that there are two distinct types of stem cells: human embryonic stem cells and induced pluripotent stem cells. Because of this application of stem cells, numerous scientific and medical possibilities have been opened up to the world, as…
