With this and other recent advances in stem cell technology, attitudes toward stem cell research are slowly beginning to change. However, other concerns related to using iPS cells still...
Although research into adult stem cells is promising, adult stem cells may not be as versatile and durable as are embryonic stem cells. Adult stem cells may not be able to be manipulated to produce all cell types, which limits how adult stem cells can be used to treat diseases.
However, as the embryo develops, stem cells become more specialised and can only develop into certain cell types. In adult humans, these specialised stem cells are referred to as adult stem...
Because of the potency of stem cells, medical researchers are pursuing further stem cell research that can help develop new treatments for different kinds of ailments such as diabetes, cardiac disease, Parkinson’s, Huntington’s Disease, and other neurodegenerative diseases.
The moral and political controversy arises from the fact that extracting the stem cells destroys the blastocyst. It is important to grasp the full force of the claim that the embryo is morally equivalent to a person, a fully developed human being.
Embryonic stem cells divide more rapidly than adult stem cells, potentially making it easier to generate large numbers of cells for therapeutic means. In contrast, adult stem cell might not divide fast enough to offer immediate treatment.
Stem cells can become many types of cells in the body, from muscle to brain, and can repair damaged tissue. But they are approved only for treating some blood conditions, for skin grafts and...
With alternatives to hES cells now available, the debate over stem cell research is becoming increasingly irrelevant. But ethical questions regarding hES cells may not entirely go away.
Laboratory research on adult stem cells is generally uncontroversial. Research with human subjects becomes controversial because some experimental “therapies” could harm patients.
There were two main issues concerning stem cell research with both pros and cons: How the knowledge will be used; Concerns about the methods; The first issue is really not just about stem cell research, as it may be applied to most research about human health.
