There are three general types of stem cells, adult, umbilical cord blood, and embryonic stem cells. Adult stem cells are found in many tissues and embryonic stem cells are usually derived from in vitro fertilization. People worry that this is taking research too far down paths that make them feel uncomfortable. Others think it is utterly immoral and against their religious beliefs. But many
Americans feel equally passionate that stem cell research should be allowed. One critic argues,
“It is a concern to help particularly vulnerable people by making sure that they are included in efforts to preserve life and health” (Kilner 684).
Each day, more is discovered about stem cells and an increase in clinical trails for stem cell therapies are conducted. It is necessary that stem cell research for all types of stem cells not only continues, but also grows and develops as time passes, for stem cell research has the ability to change the future. Each type of stem cells has many potential benefits that are waiting to be discovered and perfected to help people live a better quality of
