Stem Cell Research advances our understanding of how we develop from a single cell and how healthy cells take the place of damaged cells in living organisms. This area of study is leading scientists to believe that stem cells could eventually be used to treat diseases. ... Stem cells are one of the most fascinating areas of biology today. But like many expanding fields of scientific inquiry, research on stem cells raises scientific questions as rapidly as it generates new discoveries. One of the most popular scientific topics of discussion today, stem cell research creates as many scientific, moral and religious questions as it generates new discoveries.
Stem cells are different from other type of cells in two important ways. ... And also, they can multiply for long periods of time through cell division. ... Research on stem cells is primarily done with cells from animals and humans. However there are two types of stem cells, embryonic stems cells and adult stem cells. Embryonic stem cells come from embryos. Most of the embryos used for research have been created for infertility purposes through in-vitro fertilization and are left over excess from the procedure. Embryonic stem cells can also come from fetuses that have been aborted. Adult stem cells come from the midst of differentiated cells in living organisms. ... It is assumed that the cells used for this research, whether embryonic or adult, that they have been donated for research with the informed consent of the donor.
Stem cells are important for many reasons. In an embryo that has reached blastocyst (3 to 5 days old), a small group of approximately 30 cells or "inner cell mass" starts a process that creates hundreds of highly specialized cells that make up a fully functioning organism. In a human fetus, stem cells give rise to the many specialized cells that make up the heart, brain, lung, skin and other tissues. ... Many scientists have predicted that stem cells may become the basis for treating diseases like diabetes, heart disease or Parkinson’s disease.
