Researchers hope stem cell studies can help to:
Increase understanding of how diseases occur
. By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers may better understand how diseases and conditions develop.
What are 3 ethical issues with using stem cells in medicine?
| Phase of research Ethical issues | 1. Payment to oocyte donors | 2. Medical risks of oocyte retrieval | 3. Protecting reproductive interests of women in infertility treatment | Use of stem cell lines derived at another institution Conflicting legal and ethical standards |
|---|
What are the main disadvantages of using stem cells for medical treatment?
- Limitations on ASC ability to differentiate are still uncertain; currently thought to be multi or unipotent.
- Cannot be grown for long periods of time in culture.
- Usually a very small number in each tissue making them difficult to find and purify.
What are the advantages and disadvantages of stem cells in medicine?
| Stem cell type Limitations Advantages | Embryonic stem cells (1) Ethical dilemmas (2) Possible immune rejection after implantation (3) Only a small number of differentiated cardiomyoctes can be generated (4) May lead to teratocarcinomas (5) Genetic instability Can differentiate into cells of all three germ layers |

Why are stem cells important?
Why are stem cells important? Stem cells are the body’s “master cells.”
They are the building blocks of all organs, tissues, blood and the immune system
. In many tissues they serve as an internal repair system, regenerating to replace lost or damaged cells for the life of a person.
What is the importance of stem cells in our body?
Stem cells
provide new cells for the body as it grows, and replace specialised cells that are damaged or lost
. They have two unique properties that enable them to do this: They can divide over and over again to produce new cells. As they divide, they can change into the other types of cell that make up the body.
What are stem cells ethical issues?
Oocyte harvesting, which is essential to the creation of human embryonic stem cells raises concerns related to safety of the donor. Other important ethical issues relate to
informed consent of both donors of gametes and embryos as well as recipients of stem cells and stem cell products
.
Why we shouldn’t use stem cells?
Opponents argue that the research is unethical, because
deriving the stem cells destroys the blastocyst, an unimplanted human embryo at the sixth to eighth day of development
. As Bush declared when he vetoed last year’s stem cell bill, the federal government should not support “the taking of innocent human life.”
What are issues about 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. Adult stem cells are also more likely to contain abnormalities due to environmental hazards, such as toxins, or from errors acquired by the cells during replication.
What are 3 effects of stem cell treatment to a person?
Studies have discovered that stem cell therapy can help
enhance the growth of new healthy skin tissue, enhance collagen production, stimulate hair development after incisions or loss, and help substitute scar tissue with newly developed healthy tissue
.
Which is the biggest disadvantage of using adult stem cells for medical treatments?
Some disadvantages of adult stem cells:
Not (yet) as versatile as embryonic stem cells
. Adult stem cells can be more difficult to identify and retrieve.
What are stem cells give the importance and provide examples?
Studying stem cells
may help explain how serious conditions such as birth defects and cancer come about
. Stem cells may one day be used to make cells and tissues for therapy of many diseases. Examples include Parkinson’s disease, Alzheimer’s disease, spinal cord injury, heart disease, diabetes, and arthritis.
Are stem cells a good treatment tool for human diseases?
Stem cells have the potential to treat a wide range of diseases
. Here, discover why these cells are such a powerful tool for treating disease—and what hurdles experts face before new therapies reach patients.
What kind of financial societal impacts would stem cell therapy have on the healthcare system?
The report looked at the impacts of CIRM funding on both the state and national economy from the start of the Stem Cell Agency in 2004 to the end of 2018. The estimated impacts from the report are:
$10.7 billion of additional gross output (sales revenue) $641.3 million of additional state/local tax revenues
.
Why are doctors and scientists so excited about human embryonic stem cells?
Why are doctors and scientists so excited about stem cells?
Stem cells have potential in many different areas of health and medical research
. Studying stem cells will help us to understand how stem cells transform into the array of specialized cells that make up the human body.
Social issues
Much of the research is being carried out by commercial clinics, so reported successes are not subject to peer review.
Patients could be exploited by paying for expensive treatments and being given false hope of a cure as stem cell therapies are only in their developmental stages
.
Why are stem cells controversial?
Stem cell debates have motivated and reinvigorated the anti-abortion movement, whose members are concerned with the rights and status of the human embryo as an early-aged human life.
They believe that embryonic stem cell research profits from and violates the sanctity of life and is tantamount to murder
.
