What Makes Stem Cells So Special?

Stem cells can become any cell type in your body, similar to blank pages in a book. Specific cells in your body have predetermined functions, such as muscle cells for movement or brain cells for thinking, but stem cells work differently. These stem cells stay undecided about their future roles. Their two unique abilities come from their capacity to reproduce endlessly and to transform into specialized cells when the body needs repairs. Whoever thought we would have a little medical mechanic industry waiting for us to give it the word?

The cells possess two distinct capabilities: they reproduce infinitely to generate additional stem cells, and they evolve into specific cells when the body requires maintenance. It seems the reservoir is never tapped out, as they are always replenished. Stem cells transform into skin cells when skin injuries occur. Stem cells may develop into heart muscle cells when the heart experiences damage. Almost miraculously, these cells can learn just about any function instantly.

I recall a biology professor explaining that implanting eye stem cells in someone’s abdomen would result in the development of a non-functioning eye. That sounds like something from a science fiction movie. But it might be possible.

Your Body’s Hidden Stem Cell Factories

Stem cells exist throughout the entire body as your internal repair team, which operates unnoticed. Bone marrow represents the most well-known stem cell habitat because it exists as a soft, jelly-like tissue inside bones. Blood stem cells reside in bone marrow to produce red blood cells for oxygen transport and white blood cells for infection defense, while making platelets for bleeding control.

But that’s just the beginning. The brain contains stem cells that have the potential to generate new brain cells. Neural stem cells (NSCs) are indeed found in the hippocampus, a brain region crucial for learning and memory. If they’re there, why can’t we use them? That’s one of the secrets that is still to be unlocked.

The skin contains stem cells, which serve two purposes: they repair injuries and maintain skin health. Each of the muscles, as well as the liver, fat tissue, and heart, possesses its individual stem cell populations.

The discovery of new stem cell sources continues to amaze scientists. Stem cells in newborn umbilical cord blood demonstrate powerful therapeutic potential against 80 different diseases. And the stem cells found in baby teeth have gained scientific interest due to their potential future medical applications.

From Lab Bench to Bedside: Real Treatments Today

Here’s where things get really exciting. Stem cell treatments have moved beyond science fiction because they currently save the lives of patients. Blood stem cell therapies show the greatest success in treating leukemia and lymphoma patients among other cancer types. Doctors perform stem cell transplants after chemotherapy destroys a patient’s blood system to establish a new system from scratch.

The FDA approved the first gene-edited stem cell treatment, Casgevy, in 2024, marking a significant achievement in medical history. This treatment process begins with blood stem cell collection from patients, followed by genetic correction through CRISPR technology and final cell reinsertion to treat sickle cell disease and beta-thalassemia, which have long caused suffering to thousands of patients.

Ryoncil marked a significant achievement when it became the initial stem cell treatment approved for children suffering from graft-versus-host disease. Transplanted cells sometimes attack patients’ bodies during graft-versus-host disease, but these unique stem cells function as a solution to reduce dangerous immune reactions.

Research on eye diseases represents one of the most promising areas of stem cell advancement. Scientists have discovered a method to develop light-sensitive cells from stem cells located at the back of the eye. Early clinical studies demonstrate that lab-grown cells can provide vision improvements to patients with age-related macular degeneration, which ranks as a primary cause of blindness.

The trial participant who joined the study experienced such a remarkable improvement in vision that he shifted from hand movement recognition to reading letters on an eye chart. The preliminary stage of these medical trials demonstrates potential to treat vision impairment for millions of affected people.

Healing Hearts and Fixing Brains

Stem cell research reaches its peak when scientists use these cells to treat the heart and brain, which are our two essential organs. Scientists continue their research to utilize stem cells for repairing damaged heart muscle tissue following heart attack events. Researchers in Japan currently perform stem cell-derived heart muscle cell injections into heart patients, which have produced promising initial outcomes.

Scientists also investigate stem cell-derived dopamine-producing cells for brain replacement therapy to treat Parkinson’s disease and other brain disorders where dopamine-producing cells gradually die out. The clinical trials conducted worldwide have proven safety standards for this procedure, while multiple patients report significant symptom relief from their conditions. If dopamine-producing cells can work with PD, how about mental disorders?

New exploratory investigations into potential applications of stem cells to treat ALS (Lou Gehrig’s disease), as well as spinal cord injuries and Alzheimer’s disease, have begun. Researchers continue to expand their studies because of promising early results from these experimental treatments,but the work must go on diligently, uninterrupted, due to a lack of research funding.

Growing Organs in the Lab

The most advanced stem cell research involves creating mini-organs through laboratory cultivation. Scientists currently conduct research on “organoids,” which are not a figment of science fiction. At the Mayo Clinic, alongside other institutions, researchers develop miniature versions of intestines, hearts, kidneys, and brain tissues from stem cells.

The miniature organs enable scientists to improve disease comprehension and facilitate secure drug testing. They can then utilize these laboratory-grown organs for preliminary drug assessments before moving forward to human trials. This method will significantly accelerate and enhance the safety of the new treatment development process.

The Numbers Tell an Incredible Story

Stem cell research has expanded at an incredible rate during recent years. The worldwide clinical trial number for stem cell products has reached 83, while researchers approved 115 trials during 2024. More than 1,200 patients have received experimental stem cell treatments, and researchers have administered over 100 billion stem cells during clinical trials without any major safety issues.

The stem cell therapy market projection indicates it will expand from $14 billion in 2023 to reach $49 billion by 2033. This monetary growth signifies the promise of new medical options for millions of patients who remain without effective treatment options for their diseases.

What This Means for You and Your Family

Most stem cell treatments remain experimental, but researchers continue to advance at an extraordinary rate. Clinical trials, together with new breakthroughs and patient hopefulness, increase every month. Medical researchers investigate stem cell applications for diabetes treatment, arthritis management, heart disease prevention, stroke treatment, spinal cord injury therapy, multiple sclerosis therapy, and various cancer types.

When pursuing stem cell treatment, choose established medical centers that offer FDA-approved procedures or participate in authorized clinical trials. Be cautious of medical clinics that advertise untested treatment methods as miracle solutions.

I have personally seen a friend’s family member be first drawn to Canada, then to Mexico, and finally to the Caribbean to seek treatment for his terminal cancer. The family spent hundreds of thousands of dollars, and he died.

The most beneficial aspect of stem cell research extends beyond disease treatment, as it reveals body healing processes and develops methods to enhance these natural recovery mechanisms. We are now looking at a new area of medicine, regenerative medicine. Scientists have discovered that stem cells serve a dual function by replacing damaged cells and releasing substances that promote the healing of other cells and minimize inflammation.

A Future Full of Hope

The present decade marks a remarkable period for stem cell research studies. Through improved understanding and advanced techniques, alongside gene editing technology, scientists can now achieve opportunities that were thought to be unattainable in the previous few years.

Researchers predict that stem cell treatments will become available for stroke recovery, spinal cord repair, organ transplant, and anti-aging purposes in the near future. Progress toward these advancements continues with each successful trial and new discovery, although we have not yet achieved this stage.

But the future is bright! The most inspiring element in this story lies in the fact that our bodies supply the answer to our medical challenges. Stem cell treatments consist of human body cells that scientists enhance and direct for therapeutic purposes. Medical efforts don’t battle against natural processes because we are learning to make better use of them. Each time I hear of an advance, it brings new enthusiasm for research, and the key is to keep funding this research because there is more to find.

Stem cells represent a unique prospect for future medical science to allow our body’s natural wisdom and healing capabilities to work alongside medical advancements to enhance human longevity and well-being. This discovery goes beyond good science because it represents authentic hope.

Human brain organoids (HBOs) are made in a lab from human stem cells and look and work like parts of the brain. Since it is clearly impossible to study living humans, scientists have been using animal models and cultured neuronal cells to discern how diseases work. However, these methods still have important differences with real brains, such as how they are organized in three dimensions and differences between species, making it hard to study how the higher brain works. These problems can be addressed in a new way with HBO.

In addition to stem cells, researchers have discovered a new source of research material, one that had never been considered in the past; amniotic fluid. During pregnancy, a baby sheds cells into the amniotic fluid surrounding and protecting it.

As a baby grows inside the womb, these cells mix with the amniotic fluid. Now, scientists have shown that they can use those cells to make organoids, which are three-dimensional structures that look and work like human organs. In one case, the organoids were the kidneys, small intestines, and lungs. Organoids might help physicians learn more about how fetal organs are growing, which could lead to earlier detection of birth defects like spina bifida.

It is not the first time organoids have been made from baby cells. Other groups have grown them from baby tissue that was thrown away. But this group is one of the first to make organoids from cells taken from amniotic fluid.

The idea is innovative, and organoids made from fetal fluid have shown it to work. But there is still room for improvement in how you describe the cells that are there.

For many years, scientists have known that fetus cells are in the amniotic fluid. With amniocentesis, a needle is used to take a sample of the fluid. This lets physicians discern conditions like Down syndrome and sickle-cell disease before the baby is born. At least 95% of these cells the baby is shedding are dead.

Organoids made from baby cells have been made before. Other groups have grown them from leftover fetal tissue. On the other hand, one group is the first to make organoids from cells taken from amniotic fluid. It does not affect the baby.

Most people have heard of mini-brains, which are groups of neurons meant to fire in a way similar to how cells fire in a real brain, but not quite. There have been heated arguments about whether these tiny blobs could ever be aware, feel pain, or think, and whether they should even be called “mini-brains” because they differ from a fully developed human brain.

In another area, thyroid disease, a breakthrough may benefit those who suffer from thyroid disease. One study group working on thyroid cells has successfully used stem cells to make tiny thyroids that can be transplanted into mice, but not humans yet.

Hypothyroidism, or an underactive thyroid, affects about 5% of people and can cause tiredness, aches and pains, weight gain, and sadness. It can also change the way children’s brains grow. And people who have it often have to take a treatment every day to replace their hormones. This team’s efforts resulted in getting mice to make thyroid hormones again, which opened the door for humans. About which therapies will work with cancer, there is hope there, too, derived from studies of organoids.

Patient-derived organoids (PDOs) are new and strong pre-clinical models. However, it is still not clear how well they can predict how patients will do in the clinic. What effects will certain treatments have on a patient’s cancer? Organoids made from patients did help predict how well treatment would work for metastatic gastrointestinal cancers.

Researchers also use organoids to study how the host and bacteria interact. Adding immune system parts to infected organoids would be the next step in this direction. A few methods using triple co-cultures have been created, most of which try to replicate harmful illnesses with viruses or bacteria. In all these important research findings, one consideration must be in the mix; ethics with animal brain organoids and simple organoids in dishes.

Until now, these human brain organoids have only been found in test tubes. The most advanced ones are about the size of a pea and pulse with the electrical activity that makes real brains work. In a way that is similar to brains, they make new neurons. They also build the six layers of the human cortex, which is where thinking, speaking, making decisions, and other complex cognitive processes happen.

Many experts in the field do not think an organoid in a dish can think, but we need to talk about this. While we are discovering new ways to combat illness and developmental issues through the use of these organoids, we are also faced with ethical issues all along the way. Each of these issues must be addressed in a way that will benefit everyone and not inhibit the growth of science in its quest for health.

Dr. Igel’s distinguished career spans both academia and clinical practice. As a Clinical Assistant Professor of Medicine in the Division of Endocrinology, Diabetes, and Metabolism at Weill Cornell Medicine, and an Attending Endocrinologist at NewYork-Presbyterian Hospital/Weill Cornell Medical Center, Dr. Igel has demonstrated unparalleled expertise in the management of a wide range of endocrine disorders, with a specific focus on weight management, post-bariatric surgery care, type 2 diabetes, and other related conditions.

His commitment to advancing diabetes care is evident in his innovative approach, particularly in addressing the often-overlooked connection between diabetes and obesity. Dr. Igel emphasizes a weight-centric approach to diabetes treatment, advocating for medications that are either weight-neutral or lead to weight loss. This approach challenges the status quo in healthcare, where the impact of certain diabetes medications on weight gain is often disregarded.

“The link between diabetes and obesity is complex, and addressing it requires a comprehensive approach,” says Dr. Igel. “We know that over 11% of Americans have diabetes, and a large percentage are actually undiagnosed. Many individuals are in a progression towards diabetes, and much of that progression is closely tied to weight gain that occurs throughout someone’s lifetime. This is why we are committed to continuing our work to improve diabetes care and raise awareness of the critical connection between obesity and diabetes.”

“It is a privilege to recognize Dr. Leon Igel as the Medical Honoree of the Year,” said ADA’s Research Dinner Executive Committee Chair Gil Bashe, Finn Partners. “Obesity is a common, chronic, and progressive disease that is linked to a significant number of diabetes cases every year, and Dr. Igel’s dedication to reshaping diabetes care through his groundbreaking work in obesity management will help improve the lives of many people. His innovative approach and unwavering commitment are invaluable contributions to the field.”

As part of the Intellihealth team, Dr. Igel’s contributions extend beyond clinical practice. Intellihealth is at the forefront of leveraging innovative solutions to improve patient outcomes.
