Can stem cell research be done without embryos?

Can stem cell research be done without embryos?

“It may not be necessary to create an embryo to acquire embryonic stem cells. Our research findings demonstrate that creation of an autologous pluripotent stem cell — a stem cell from an individual that has the potential to be used for a therapeutic purpose without an embryo — is possible.

Does stem cell research use embryos?

The embryos being used in embryonic stem cell research come from eggs that were fertilized at in vitro fertilization clinics but never implanted in a woman’s uterus. The stem cells are donated with informed consent from donors.

Are embryonic stem cells necessary for science?

Adult stem cells are more specialized; they generally make cells only from their tissue of origin. Thus, embryonic stem cells can do things that adult stem cells cannot do. To maximize the chances of discovering new cures, it is essential to pursue research on both embryonic and adult stem cells.

Why are scientists interested in embryonic stem cell research?

Scientists are investigating how stem cells form tissues and organs, how aging impacts their function and their role in various diseases and conditions. A better understanding of the inner working of living organisms leads to earlier detection, better diagnosis and more effective treatments for diseases and injury.

Are there any alternatives to collecting stem cells without killing embryos?

Still other alternatives include making embryonic stem cells that stop developing on their own (called “dead” or “arrested” embryos) or genetically engineering sperm, egg or donor nucleus so that embryos would be unable to move past a certain point in development.

Why is embryonic stem cell research controversial?

However, human embryonic stem cell (hESC) research is ethically and politically controversial because it involves the destruction of human embryos. In the United States, the question of when human life begins has been highly controversial and closely linked to debates over abortion.

Why do scientists want to use stem cells?

Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it. Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury.

Should embryos be used for research?

Many hold a middle ground that the early embryo deserves special respect as a potential human being but that it is acceptable to use it for certain types of research provided there is good scientific justification, careful oversight, and informed consent from the woman or couple for donating the embryo for research (5) …

Why do scientists want to use stem cells lines?

Scientists want to have a variety of stem cell lines so that they can pick the best ones for their experiments. Scientists hope to grow these stem cells into tissues afflicted by the disease, the better to assess and perfect treatments. (As of April 2007, none of these lines are eligible for U.S. government funding.)

What would the scientists use embryonic stem cell lines for?

Stem-cell lines are used in research and regenerative medicine. They can be used to study stem-cell biology and early human development. In the field of regenerative medicine, it has been proposed that stem cells be used in cell-based therapies to replace injured or diseased cells and tissues.

What are the alternatives to embryonic stem cells?

Alternative Stem Cell Sources

• Embryonic Stem Cells. Embryonic stem cells are isolated from embryos.
• Somatic Cell Nuclear Transfer (SCNT)
• Induced Pluripotent Stem (iPS) Cells.
• Adult Stem Cells.

What are scientists hoping to do with stem cells?

Potential uses of stem cells Since stem cells have the ability to turn into various other types of cells, scientists believe that they can be useful for treating and understanding diseases. According to the Mayo Clinic, stem cells can be used to: grow new cells in a laboratory to replace damaged organs or tissues.

What are the benefits of embryonic stem cell research?

Embryonic stem cells are pluripotent , meaning they are more versatile in research studies than adult stem cells. The potential benefits of embryo research include discovering new ways of treating diseases, injuries and organ failure.

Embryonic stem cell research is controversial because it requires the destruction of embryos to use the stem cells in research.

What are the arguments for stem cell research?

The stem cell research debate also has many arguments that are pro research. The primary argument for stem cell research is the medical use of stem cells. The argument is positive medical uses of stem cells outweigh moral and ethical concerns. Using stem cells may cure diseases and save lives.

What are ethical issues in stem cells?

The main ethical issue regarding stem cell research is that embryonic stem cells come from embryos – that are ruined eventually. This causes the public to raise ethical issues concerning the moral status of the human embryo and reasons behind the idea to destroy it.
