According to a new research, stem cell therapy was used on heart disease patients. It was found that it can make their coronary arteries narrower. A disadvantage of most adult stem cells is that they are pre-specialized , for instance, blood stem cells make only blood, and brain stem cells make only brain cells.
What are some advantages or disadvantages of using stem cells?
| 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 |

What are the benefits of stem cell research?
Researchers and doctors 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 and doctors may better understand how diseases and conditions develop.
What are the possible benefits and issues of stem cell research?
Stem cell research can potentially help treat a range of medical problems . It could lead humanity closer to better treatment and possibly cure a number of diseases: Parkinson’s Disease. Alzheimer’s Disease.
What are the disadvantages of stem cell research?
- Embryonic stem cells can have high rejection rates. ...
- Adult stem cells have a determined cell type. ...
- Obtaining any form of stem cell is a difficult process. ...
- Stem cell treatments are an unproven commodity. ...
- Stem cell research is a costly process.
How much does stem cell treatment cost?
Stem cell therapy cost can range anywhere between $5000 – $50,000 . Patients must do their research and ask as many questions as they can before financially committing to treatment.
Are there current stem cell treatments already?
Currently, the only stem cell-based treatment that is routinely reviewed and approved by the U.S. Food and Drug Administration (FDA) is hematopoietic (or blood) stem cell transplantation . It is used to treat patients with cancers and disorders that affect the blood and immune system.
What are the risks of using stem cells?
The risks to research participants undergoing stem cell transplantation include tumour formation, inappropriate stem cell migration , immune rejection of transplanted stem cells, haemorrhage during neurosurgery and postoperative infection.
What are two disadvantages of using stem cells?
A disadvantage of most adult stem cells is that they are pre-specialized , for instance, blood stem cells make only blood, and brain stem cells make only brain cells. These are derived from embryos that are not a patient’s own and the patient’s body may reject them.
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 is the success rate of stem cell therapy?
Stem cell treatment has achieved positive results in over 45% of patients , according to one trial. Patients saw improvement in less than 6 months, which compares quite well with back surgery that usually involves very long recovery times.
Why are people against stem cell research?
Some opponents of stem cell research argue that it offends human dignity or harms or destroys human life . Proponents argue that easing suffering and disease promotes human dignity and happiness, and that destroying a blastocyst is not the same as taking a human life.
What diseases are treated with stem cells?
- Acute leukemia.
- Amegakaryocytosis or congenital thrombocytopenia.
- Aplastic anemia or refractory anemia.
- Chronic lymphocytic leukemia.
- Familial erythrophagocytic lymphohistiocytosis.
- Myelodysplastic syndrome of another myelodysplastic disorder.
- Osteopetrosis.
Where is the best stem cell center in the world?
Stem Cell Institute (Panama)
Founded by Dr. Neil Riordan, a globally recognized stem cell expert and visionary, the Stem Cell Institute in Panama is among the world’s leaders in stem cell research and therapy.
How long does it take for stem cell therapy to work?
Most patients feel no improvement for at least 3 weeks and possible 6-8 weeks . Once you feel improvement, you will notice continued improvement expanding over 6 months.
Can stem cells reverse aging?
Stem cells combined with anti-aging genes can potentially absorb the process of cellular aging. The introduction of “youthful” stem cells into the human body can rejuvenate existing cells and allow the body to age more gracefully & even reverse some effects of the aging process.
