Parkinson’s disease (PD) is the second most predominant neurodegenerative disorder worldwide, affecting over 10 million people. Characterized by a slow and progressive loss of control of the neurological system as a result of dopamine depletion, symptoms of PD often include tremors, slowed movement, impaired posture and balance, and gradual loss of automatic movements.
While PD cannot be cured, current treatment is focused on alleviating symptoms and slowing the progression of the disease. Specifically, deep brain stimulation or therapies to increase DA levels by administering a DA precursor are the available therapy options for PD.
However, research has found that DA precursor therapy has little effect on the progression of PD and its efficacy decreases as the disease progresses.
Recent progress in the clinical understanding of regenerative medicine and its properties associated with stem cell therapy has provided the opportunity to evaluate new and potentially effective methods for treating a wide range of neurodegenerative illnesses, including PD. Specifically, mesenchymal stem cells (MSCs) have been found to be the most promising form of stem cell and have demonstrated the ability to differentiate into dopaminergic neurons and produce neurotrophic substances.
In this review, Heris et al. discuss the application of MSCs and MSC-derived exosomes in PD treatment.
Research has identified dysregulation of the autophagy system in the brains of PD patients, suggesting a potential role for autophagy in PD. In PD models, MSCs may activate autophagy signals and exhibit immunomodulatory effects that alleviate inflammation and improve tissue healing; this type of treatment had previously been used in treating various forms of neuroinflammatory and neurodegenerative illnesses.
The authors indicate that MSCs can be administered either systemically or locally. While systemic transplantation allows MSC-based treatment of pathologies affecting the entire body, local transplantation aims to alleviate symptoms associated with illnesses that originate from certain organs and is performed through intramuscular or direct tissue injection.
Research has also demonstrated that stem cell-derived dopaminergic transplants could be a suitable method for the long-term survival and function of transplants; in the case of MSC therapy, the average dose in animal models is usually 50 million cells for each kg of weight.
MSC-derived exosomes demonstrate therapeutic characteristics similar to their parents, have the ability to avoid whole-cell post-transplant adverse events, have a high safety profile, cannot turn into pre-malignant cells, and no cases of immune response and rejection have been reported.
While the use of MSCs in the treatment of PD continues to show potential, Heris et al. point out that many of the clinical trials have had few participants and can be costly. Considering these limiting factors, the results from these studies are not able to be generalized to everyday medical care without further clinical studies to address these concerns.

Stem cells respond to signals released by damaged or diseased tissue by differentiating in an effort to replace these cells.
As researchers continue to learn more about the various applications of stem cells as they relate to the body’s healing process, they’ve discovered two significant issues relating to the process of stem cell application. The first issue involves various methods that enable the stem cell transformation to targeted cells or successful engrafting. The authors of this review indicate that there are many proposed solutions to this issue, which are not covered as part of this review.
In this review, Maric et al. address the second known issue, analyzing cell homing. More specifically, understand how to direct the migration of most of the transferred cells to the desired location. Research has demonstrated that the greater the number of administered stem cells, the better the treatment outcomes. However, research has also indicated that there is a saturation plateau where no additional benefit has been achieved.
Previous studies have demonstrated positive results for non-invasive methods of stem cell transplant. However, it’s typical for stem cells to dissipate to other organs rather than to the brain, which are the targeted areas for a wide spectrum of neurodegenerative diseases.
Reviewing the existing research on stem cell homing, the authors draw a number of conclusions, including the location of the stem cell injection site impacts the homing results with better migration results when injections are closer to the targeted locations; preprocessing may increase homing efficiency; there are a number of potential methods that may improve the homing mechanisms; understanding the mechanism of neurodegenerative disease is essential to understanding the homing process and to predict the engraftment results; stem cells improve the plasticity of the brain; and that intrathecal application has many benefits, fewer adverse effects, and has been shown to be safe.
Additionally, Maric et al. raise issues that require further study, including evaluating the discrepancy between in vivo and in vitro results; paying more attention to the prospects of mathematical, physical, and computer models and simulations; investigation of real-time development and spatial information of the homing processes; and the need for a deeper understanding of homing mechanisms in homing mechanisms in intrathecal and other ways of administration.
The authors conclude that, in the case of neurodegenerative diseases, intrathecal application of stem cells via direct delivery to the cerebrospinal fluid has the advantage of no blood-brain barrier restriction, further study into the long-term study of what specifically slows the migration of injected cells is required.

No one wants to grow old. That is apparent from the huge amounts of money people spend on anti-aging products and services each year. These products and services include everything from lotions to more invasive options like plastic surgery.
However, healthier aging is possible without relying on invasive procedures. Stem cell rejuvenation, for example, offers promising results for people searching for ways of going through a healthier aging process.
Intrinsic vs. Extrinsic Aging: What to Know
Intrinsic aging refers to the various traits you inherited, including collagen and elastin production levels, hormonal balance, and more. The thinning lips or particular types of wrinkles you see on your parents, for example, are intrinsic aging traits, and you will likely deal with them as you age, too.
Intrinsic aging doesn’t just refer to visible signs of aging. It also includes the damage that occurs to organs and other body tissues as you get older. How fast an organ deteriorates and how fast tissues regenerate to keep up with the damage all depends on intrinsic aging.
Extrinsic aging refers to the things that you can control about aging. It includes lifestyle choices like smoking, not eating correctly, and so much more.
Both intrinsic and extrinsic factors in aging begin to accumulate, sending messages of aging to the core of stem cells. Thus, everything associated with aging can be seen through the lens of stem cells.
Understanding Stem Cell Rejuvenation
Introducing youthful stem cells into the body can make it easier to rejuvenate existing cells, helping the body age in a healthier way and even offering the chance to reverse some of the effects of aging.
As you age, your cells are not as efficient at replicating as they were when you were younger. This leads to cells getting damaged and dying off. Inefficiency in cell replication leads to aging bodies.
Stem cells are the cells that create specialized cells. They are your body’s building blocks. To combat the natural aging process, stem cells can help regenerate damaged tissue. This is because they can be made into various cell types.
Stem cells can also stimulate the production of growth factors and other molecules that trigger healing mechanisms, helping maintain healthy tissues. Chronic, low-grade inflammation is associated with aging, and stem cells help to reduce inflammation.
They do this by impacting the processes of white blood cells. Macrophages are white blood cells that are integral to the immune system. M1 macrophages can create inflammation, while M2 macrophages reduce it.
Stem cells help transform M1 macrophages into M2 macrophages. This stimulates the process of reducing inflammation.
Another way stem cells help battle against the aging process is by modulating the immune system. They have the potential to maintain a healthy immune system and delay the type of immune dysfunction that comes with age.
Oxidative stress also plays a role in aging. Free radicals damage cells, leading to many of the issues the aging process causes. Stem cells help combat the effects of oxidative stress.
Stem cells also have the potential to affect visible signs of aging. They can increase collagen production, which is vital for maintaining skin flexibility and firmness. As part of the aging process, your collagen production decreases, leading to the formation of fine lines and wrinkles.
The Process of Stem Cell Rejuvenation
Stem cell rejuvenation begins with choosing the right type of stem cells. The main stem cell type used is mesenchymal stem cells.
Mesenchymal stem cells (MSCs) are a type of multipotent stem cell that can differentiate into a variety of cell types. They are typically found in the stromal or connective tissue of various organs and tissues in the body.
MSCs were first identified in the bone marrow, but they can also be isolated from other tissues such as adipose (fat) tissue, and umbilical cord tissue.
MSCs possess immunomodulatory properties, meaning they can regulate the immune system. They can influence the activity of immune cells, such as T cells and macrophages, and have anti-inflammatory effects. This makes them potentially useful for treating conditions with immune system dysregulation.
MSCs exhibit low immunogenicity, meaning they are less likely to provoke an immune response when transplanted into a recipient. This characteristic makes them potentially suitable for allogeneic (from a donor) transplantation.
MSCs have been studied for their potential therapeutic applications in regenerative medicine, tissue engineering, and treatment of various diseases, such as autoimmune disorders, cardiovascular diseases, and musculoskeletal conditions.
If from a patient’s own tissues, the healthcare provider extracts the stem cells and prepares them for injection. They then inject the stem cells into the treatment area to provide relief from inflammation while encouraging your body to start regenerating tissues at the same time.
Because stem cells have the ability to endlessly duplicate themselves, the benefits of stem cell therapy for rejuvenation purposes can only improve over time.
Benefits of Stem Cell Rejuvenation
Stem cell rejuvenation procedures are minimally invasive. They require an extraction of stem cells and then an injection or the introduction of an IV. Other procedures that target aging can be significantly more invasive, leading to long recovery times.
The results continue to improve over time. This is because stem cells will go on to multiply where they were injected, potentially leading to more powerful results.
Stem cell rejuvenation can target the aging process at the cellular level, helping reduce inflammation and prevent oxidative stress. Stem cells may lead to an increase in collagen production as well, which helps combat fine lines and wrinkles.
Choosing Regenerative Medicine
Anti-aging solutions don’t have to involve invasive procedures or the reliance on options that take a very long time to work. Regenerative medicine treatments like stem cell therapy offer the chance to tackle the causes of aging at the cellular level.
Stem cells can offer anti-inflammatory results while also targeting free radicals and helping repair damaged tissues as well as damaged stem cells. By turning to regenerative medicine options, you have the chance to find rejuvenation solutions that can work.

Erectile dysfunction (ED) is a disorder that affects the quality of life and the sexual relations of more than half of the male population aged over 40 years. Currently, it’s estimated that his disorder will affect more than 300 million men in the next five years.
According to the Mayo Clinic, male sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles, and blood vessels. Erectile dysfunction can result from a problem with any of these. Additionally, stress and mental health concerns can cause or worsen erectile dysfunction.
The treatment of ED has traditionally been based on the temporary enhancement of penile erection but without a permanent treatment option. Current temporary treatment options include phosphodiesterase type-5 inhibitors (PDE5is) such as vardenafil, avanafil, tadalafil, and sildenafil, which are the most widely known and used medications for the treatment of ED.
Unfortunately, the treatment failure levels associated with these drugs are high, with unresponsive rates ranging between 20 and 40%. These failure rates often require the use of additional treatment options for the management of ED, including the use of intracorporeal injections, vacuum erection devices, and penile prosthesis implantation. However, the use and application is also limited due to the high cost, intolerance to side effects, pain, and unsatisfactory results.
Recently, several studies have suggested the use of stem cells for the treatment of ED to be promising in terms of damaged tissue repair as well as clinical efficacy.
In their review of current literature, Protogerou et al. evaluate and summarize the methods of administration, the cell types used in the performed clinical trials, and the safety and efficiency of procedures designed to treat ED.
Specifically, the authors reviewed 10 clinical studies published between 2010 and 2020 and used bone marrow-derived stem cells (BMSCs), adipose tissue-derived stem cells (ADSCs), umbilical cord stem cells, and placenta-derived stem cells. One of the studies reviewed also examined the re-administration of stem cells as a potential therapeutic option. From the authors’ findings, each study demonstrated encouraging results characterized by improved sexual function with no side effects.
Protogerou et al. also point out a number of limitations with these studies, including each being a small study with a short follow-up period, various etiologies of ED, and without control groups.
Despite these limitations, the authors highlight the urgent need for a double-blind randomized controlled study for the clinical effect of stem cell treatment in ED to sufficiently understand the ideal therapeutic strategy for using stem cell therapy to treat ED.

After suffering an injury or experiencing any kind of damage to your body, it’s common to worry about how long the recovery process will take and wonder how soon you’ll be back to your normal self. The answer greatly depends on your physical health, the type of injury you face, and the treatments you’re receiving.
By understanding the drawbacks some traditional treatment options offer, especially when speaking about orthopedic injuries, and knowing more about options like stem cell therapy, you’ll be better able to make informed decisions about your treatment. Learn more about how regenerative medicine options, such as stem cell therapy, can impact the recovery process.
Why Traditional Treatments Aren’t Always Right
In orthopedics, healing takes significant time. It’s important to note, however, that one of the most common treatment options — surgery — only extends the time necessary to fully heal.
The typical healing period for someone who has undergone orthopedic surgery, even minimally invasive options, is several weeks. And that time refers only to the healing needed so that you can be up and walking around again — it does not mean being back to your full strength or regaining your flexibility.
This is why it’s common to see professional athletes take several months to recover after an injury that required surgery. As you recover, you also have to take pain medications and other drugs.
If you don’t choose the surgery route, another traditional option is steroids. These relieve pain and reduce inflammation, but they cause more damage to the injured area. They can cause a decrease in blood supply to the bones in the joints, leading to them weakening. Also, they can potentially accelerate cartilage damage.
Turning to pain medications alone does help reduce pain, but because they don’t do anything to fix the problem causing the pain in the first place, all painkillers do is prolong the issue. Long-term use of pain medications has its own health risks, which you will want to weigh against the benefits the medications provide.
Taking steroids and turning to painkillers will generally only delay the need for surgery. They don’t stop the progression of the problem that causes pain, allowing it to worsen while masking the symptoms. And while surgery is often successful at treating the injury, its cost and invasiveness mean it is not a viable option for everyone.
Understanding Stem Cell Therapy
Stem cells are your body’s building blocks. They are the cells that divide to form daughter cells that become other stem or specialized cells.
Stem cells can generate healthy cells to replace those damaged or affected by disease. They can be guided to become specialized cells, helping repair and regenerate tissues throughout the body.
There are three types of stem cells — embryonic, perinatal, or adult stem cells. Embryonic stem cells come from donated embryos that are three to five days old and contain an inner cell mass. These are pluripotent cells, meaning they can become any type of cell in the body or more stem cells. Due to the controversy of using these stem cells, they are primarily used in research only.
Perinatal stem cells come from amniotic fluid or umbilical cord blood. These stem cells can transform into specialized cells.
Adult stem cells are present in most tissues in the adult body, including fat tissues, bone marrow, or umbilical cord tissue. Although their abilities are slightly more limited than those found in embryonic stem cells, they are still potent and can create all kinds of human cells. Adult stem cells break down into many different types, including:
- Mesenchymal stem cells
- Hematopoietic stem cells
- Skin stem cells
- Neural stem cells
- Epithelial stem cells
Stem cell therapy refers to the use of stem cells to promote the repair response of injured, diseased, or dysfunctional tissues. Stem cell therapy requires the preparation of the cells, which are usually obtained from your body and then injected into the treatment area.
How Stem Cell Therapy Helps
Stem cell therapy stimulates your body’s natural healing response. When a part of your body has inflammation, which is a natural response to an injury, it receives less blood.
The stem cell therapy reduces inflammation, which helps decrease pain while also improving blood circulation. More blood means the injured area receives the nutrients and oxygen it needs to heal itself.
Stem cell therapy allows for the management and healing of the problem. It doesn’t just mask the symptoms or delay the need for surgery; instead, it helps the formation of healthier tissues in the areas where they are needed.
Another benefit of stem cell therapy is that it doesn’t require any invasive procedures. All that is necessary is to extract stem cells from your body and enhance them before injecting them at the treatment site.
Unlike surgery, you don’t have to worry about a long recovery time or having to rely on help from others to manage everyday life as you heal. If you are someone who can’t go under general anesthesia, this is an option to consider. It is an outpatient procedure, allowing you to go home right after.
With stem cell therapy, you also don’t have to stress about participating in physical therapy for months, as you would have to do after surgery. It is an option that allows you to get back to your life as quickly as possible.
Relying on Regenerative Medicine
As one of the branches of medicine that holds promising potential, people are exploring regenerative medicine options like stem cell therapy. From autoimmune diseases to sports injuries and more, stem cell therapy, platelet-rich plasma, and other regenerative medicine options can help.
Not everyone can have surgery, and not everyone wants to depend on steroids and pain medications to feel relief.
By turning to an option that focuses on getting to the underlying problem causing the pain, you have an opportunity to see faster results without worrying about a long recovery process or dealing with general anesthesia. Give your body the chance to heal itself by considering stem cell therapy.

Recent estimates indicate that one in every 10 people is affected by an autoimmune disease.
Autoimmune diseases occur when the normal function of the immune system mistakenly attacks normal and healthy cells within the body; examples of autoimmune diseases include rheumatoid arthritis, type 1 diabetes, and lupus. Currently, there are over 80 known types of autoimmune disease.
Because of their proliferation and differentiation ability, mesenchymal stem cells (MSCs) have increasingly drawn interest from the research community as a potential option for the treatment of autoimmune diseases.
In this study, Zeng et al. evaluate the efficacy and safety of MSC transplantation in the treatment of autoimmune diseases. Specifically, this review included a total of 18 RCTs involving rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), inflammatory bowel disease (IBS), ankylosing spondylitis (AS), and multiple sclerosis (MS).
Reviewing the therapeutic effects of MSCs on each of the diseases, the authors found that with the exception of MS, transplantation of MSCs may improve clinical symptoms and clinical efficacy of these autoimmune diseases. However, the authors also point out that MSCs appear to produce certain specific effects on different autoimmune diseases.
Although no obvious adverse events resulting from MSC transplantation were reported or observed during these studies, and while MSCs appear to have certain effects on different autoimmune diseases, the authors conclude that this review provides relevant evidence for the design of future clinical trials specifically assessing MSC cell source, dosage, route of drug administration, and intervention in the most ideal disease state when treating this group of diseases.
