Pros and Cons of Stem Cell

When it comes to regenerative medicine, stem cells are one of the most promising technologies. From the potential to cure diseases such as diabetes or cancer to helping those injured due to accidents or surgery, there is so much that can be done with this technology. World's first stem cell treatment was done for Spina Bifida during fetal surgery and went successful. However, the success rate doesn't mean that there cannot be problems. So, before we dive too deep into how this technology can benefit us, it's important to consider both the pros and cons of stem cells in medical treatments.

What are the Pros of Stem Cell Therapy?

Scientists and physicians are focusing on regenerative medicine and cell therapies as potential alternative treatments for various diseases. There are many advantages of stem cell technology, including:

1. Renewability

When tissue or organs are damaged, stem cells can be used to replace those that have died or been destroyed. They can also be used to repair damage caused by diseases such as cancer, stroke, and Parkinson's disease. Stem cells can self-renew, meaning they can divide to form more cells to replenish dying tissues and organs. This is different from regular body cells that lose their ability to replicate after a certain number of divisions. Stem cells are, therefore able to produce an endless supply of healthy new tissue and organs for people suffering from illness or injury.

2. Versatility

Stem cells can differentiate into any type of adult cell, allowing them to be utilized in a variety of different applications. So far, FDA has approved the use of stem cells to create specialized treatments for cancer, replace missing or damaged tissue, and even regenerate lost organs. This versatility provides researchers with a wide array of possibilities for medical treatment that can save lives or significantly improve quality of life.

3. Potential for Disease Treatment

Scientists hope that one-day stem cell technology could offer potential cures for certain illnesses that at present cannot be cured such as diabetes, Parkinson's disease, spinal cord injuries, genetic disorders such as muscular dystrophy, and more.

4. Reduced Risks of Rejection

Stem cells hold the potential to develop into any type of specialized cell and can be used to replace damaged or faulty tissue without being rejected by the body. This means that stem cells are not subject to the same kind of immune response as transplanted organs or tissues, eliminating the risk of organ rejection after transplantation. Also, stem cells have an “immortal” life span so that they can be used indefinitely in treatments and therapies without further interventions. This provides a significant advantage over other cellular therapies and treatments requiring multiple infusions due to short-living cell populations.

What are the Cons of Stem Cell Therapy?

Though there is much promise in stem cell technology, it is not without its drawbacks. Some of the potential cons of stem cell technology include:

1. There May be a Risk of Rejection

Although the therapy involves minimal risks, it can also be associated with risks of rejection in the patient's body. The stem cells taken from a donor must be carefully checked for compatibility with the recipient's body, as there is a chance that they could be rejected by the immune system or cause an autoimmune reaction. In addition, the chances of infection or tissue damage may increase due to the use of foreign cells or tissue.

2. Limited Availability

According to the Harvard Stem Cell Institute, the only stem cell treatment that the U.S. Food and Drug Administration (FDA) regularly examines and sanctions is hematopoietic (or blood) stem cell transplantation. This therapy is utilized to manage disorders and cancers that impact the immune system and blood.

Other therapies utilizing stem cells are usually experimental and have limited availability. In fact, most of these treatments can only be accessed through clinical trials or abroad.

3. Costly Treatment

In the USA, the stem cell treatment cost can range from $2500 to $20000; in Canada, the same can cost you around $20000-$50000. This makes it one of the most expensive treatments available in the medical world. The high cost of treatment may prove to be a deterrent for those who cannot afford this kind of treatment.

Due to the lack of insurance coverage or reimbursement programs, many people are unable to receive stem cell therapy because they simply can't afford it. Also, depending on where you go for the treatment, costs may vary significantly, which can be another disadvantage for some patients.

4. Controversy

One of the main controversies surrounding stem cell treatment is the ethical implications of using human embryos for research. Despite being a promising medical breakthrough, some feel that using embryonic stem cells has many moral and ethical implications that cannot be overlooked. As with any medical intervention, there are questions about the safety and efficacy of stem cell treatments.

Another major controversy surrounds the potential power struggles regarding who has access to these treatments. While many argue that those with financial resources should not have privileged access to potentially life-saving treatments over others, economic concerns must be carefully weighed against ensuring equitable access to healthcare.


Stem cell technology is a revolutionizing new field with great promise for future medical treatments. While there are pros and cons associated with the use of stem cells, much work is being done to improve the safety and effectiveness of stem cells so that more people can reap the benefits. Overall, it’s important to consider all aspects of stem cell therapy and how each therapy treats other diseases. Meanwhile, research and experiments are still underway.

Pros and Cons of Stem Cell

Frequently Asked Questions

What are the risks of stem cell therapy?

Though there is much promise in stem cell technology, it has drawbacks. Some potential cons of stem cell technology include the risk of rejection, limited availability, high cost, and ethical implications controversy.

How does stem cell therapy work?

Stem cell therapy uses human cells to replace damaged or defective cells lost through injury or disease. The goal is to use these cells to repair tissue and organs damaged by injury or illness and restore normal functioning. This can be done by transplanting donor-derived cells or the patient’s harvested stem cells that are re-introduced into their body.

Is stem cell therapy safe?

The safety of stem cell therapies depends on the specific treatment and how it is administered. It is critically important to discuss every possible with a healthcare professional before undergoing any form of stem cell therapy, as there are potential risks associated with such treatments.

What is being done to improve the safety and effectiveness of stem cell therapies?

Research and experiments continue to be conducted to improve the safety and efficacy of stem cell treatments. Such studies aim to determine the best methods of harvesting, culturing, and delivery of stem cells and explore potential new uses for stem cells in medical treatments. Efforts are being made to ensure that such therapies are accessible and affordable for all who require them.
