You've probably heard the term "Stem Cell". There's a lot of talk about this as a potential solution to many diseases that are still difficult to cure, such as diabetes, Parkinson's disease, and paralysis. So let's take a look at what these stem cells actually are, what benefits they can provide us, and why there's such a big debate about them in the world.
What are these stem cells?
Simply put, a stem cell is like a lump of clay that has no shape. We can take this lump of clay and mold it into anything we want, like a vase, a statue. That's how these stem cells can become any type of specialized cell in our body. These are the "master cells" in our body.
That is, this same type of stem cell can, depending on the need, turn into a skin cell , a heart muscle cell , a brain nerve cell , or an insulin-producing cell in the pancreas . It is because of this amazing ability that scientists have high hopes for this.
Where do we get these cells?
There are two main methods for obtaining stem cells.
1. From the adult body: In some parts of our body, for example, in the bone marrow , there are small numbers of these stem cells. These give rise to things like new blood cells. These are called adult stem cells.
2. From Embryos: This is the most talked about and controversial method. That is, these cells are obtained from the embryo, which is the first stage of human life. These are usually taken from embryos that are to be removed from couples undergoing in vitro fertilization (IVF) treatment, with their consent.
Often, when a couple looking to have children goes through IVF treatment, multiple embryos are created to increase the success rate. After one or two of them are implanted in the mother's uterus, the remaining embryos are sometimes destroyed. In many countries, it is embryos that would have been discarded anyway that have been allowed to be used for this research.
What are the amazing benefits of this technology?
Okay, now let's see what benefits we can get from these amazing cells. Imagine that cells in a part of our body have died due to a disease. What if we could replace those dead cells with new, healthy cells and transplant them into that place? That is the main goal of stem cell research.
| Medical condition | The solution that stem cells can provide |
|---|---|
| Diabetes (Diabetes Mellitus) | Diabetes occurs when the cells in the pancreas that produce insulin are destroyed. Instead, new insulin-producing cells can be created in the laboratory and injected into the body. |
| Parkinson's Disease | The disease is caused by the death of cells in the brain that produce a chemical called dopamine. Instead, new dopamine-producing cells can be created and transplanted into the brain. |
| Paralysis | It is possible to try to restore lost function by regenerating nerve cells damaged in an accident. |
| Heart Disease | These cells can be used to regenerate parts of the heart muscle damaged by a heart attack. |
But... there's a big moral issue with this.
No matter how good this technology is, there is a lot of controversy and debate surrounding the idea of obtaining these cells from embryos. There are two main opinions on this.
One side says that this could save thousands of lives. On the other hand, this uses embryos that would otherwise be destroyed. So many scientists and researchers believe that there is nothing wrong with doing good for people. They see this as a scientific tool that can save lives.
But the other side , especially religious groups and those who are strongly concerned about morality, tells a completely different story. Their argument is that an embryo, no matter how small, is the beginning of a human life. Therefore, destroying that life for the sake of research is wrong. According to them, this is creating "discarded human lives."
Simply put, their question is, 'Is it morally right to destroy another human life (even a fetus) to save one human life?'
The state and future of the world
Because of this controversy, some countries have imposed strict rules on this research. Other countries, such as England, have allowed this research to continue with restrictions. This often leaves researchers hesitant. Because a research that is carried out at great expense can suddenly stop due to a political decision.
But patients and their families who suffer from diseases like diabetes and Parkinson's have high hopes for this research to move forward quickly. That's why they are always raising their voices to support this research.
This is just a description of a technique. We also remind you to always talk to your family doctor about any medical condition you may have.
Take-Home Message
- Stem cells are a special type of basic cell that can become any cell in our body.
- There is great hope that these will be able to cure diseases like diabetes and paralysis.
- Because these are obtained from embryos, there is a huge ethical debate between those who consider it 'destroying human life' and those who consider it 'doing good with a discarded embryo'.
- This is a very complex topic. Finding a balance between scientific advancement and human morality is the biggest challenge of the future.
