What is a stem cell?
Stem cells are undifferentiated cells in our body that play a unique role. Unlike regular cells, they possess two key characteristics: self-replication and differentiation. Self-replication refers to the ability of stem cells to continuously replicate themselves and create identical stem cells. Differentiation means the ability to transform into the necessary cells, such as nerve cells or heart cells. Our bodies are made up of approximately 60 trillion cells, which age, become damaged, or die over time. However, many tissues in the body have limited or no self-healing capabilities. This is where stem cells become crucial, as they can replace or regenerate damaged cells.
① Types of Stem Cells
Stem cells can be broadly categorized into two types: embryonic stem cells and adult stem cells. Embryonic stem cells have the ability to differentiate into any cell type, offering great therapeutic potential. However, due to ethical controversies, research on them is limited. Adult stem cells are found mainly in bone marrow, fat, and blood, and they primarily function to replace damaged cells in their respective tissues. Adult stem cells are less controversial ethically, and when using autologous stem cells (from the patient’s own body), the risk of immune rejection is low. Recently, a technology called induced pluripotent stem cells (iPS cells) has advanced, allowing adult cells to be reverted to an undifferentiated state, enabling them to be used like stem cells. This technology opens up new possibilities for stem cell research.
② Main Functions of Stem Cells
Stem cells can perform various functions, such as:
• Regenerating damaged cells: Stem cells can migrate to damaged tissues, differentiate into new cells, and help regenerate the tissue. For example, they can replace damaged heart cells in patients with heart disease.
• Immune regulation: Stem cells can modulate immune responses and suppress excessive immune reactions, which can help treat autoimmune diseases.
• Vascular regeneration: Stem cells can promote the recovery of damaged vascular tissue by creating new blood vessels. This function is particularly useful in treating chronic diseases like diabetes.
What is Venous Stem Cell Therapy?
Venous stem cell therapy generally involves extracting stem cells from the patient’s veins and reintroducing them via a vein. The stem cells then circulate throughout the body and move to the required organs. However, the issue is that approximately 80% of these injected stem cells are filtered out by the lungs. This greatly reduces the effectiveness of the treatment, as the stem cells do not reach their intended target. For example, if 800 million stem cells are injected intravenously, only about 8 million reach the target organ.
What is Arterial Stem Cell Therapy?
On the other hand, arterial stem cell therapy involves extracting stem cells from the arteries and reinjecting them through an artery. Since arteries supply oxygen-rich fresh blood, the stem cells can reach the target organs at 100% efficiency. This procedure allows all the injected stem cells to directly act on the damaged area, making the effect over 100 times stronger than venous stem cell therapy. When 800 million stem cells are injected via an artery, all 800 million will reach the target organ. If you want to need more information, visit to here!

Difference in Effectiveness: Why is Arterial Stem Cell Therapy More Effective?
The most significant difference between arterial and venous stem cell therapies is how effectively the stem cells reach the areas where they are needed. This difference has a direct impact on the treatment outcome, and here are the reasons why arterial stem cell therapy is more effective.
① Stem Cell Delivery Route
In venous stem cell therapy, stem cells are injected into the patient’s veins, and they spread throughout the body, circulating in the bloodstream. However, a critical issue is that about 80% of the injected stem cells are filtered out by the lungs. Since most of the stem cells are removed in the lungs, very few reach the target organ. In contrast, arterial injection involves directly delivering the stem cells through arteries, which carry oxygen-rich fresh blood. With arterial injection, 100% of the stem cells reach the required organs or tissues without any loss in the lungs.
② Concentration and Focus of Stem Cells
Arterial injection allows for the direct and concentrated delivery of stem cells to the damaged area. A high concentration of stem cells can be delivered all at once to the target organ, resulting in immediate and powerful treatment effects. For instance, arterial injection can focus stem cells on specific organs like the kidneys or heart, maximizing the regenerative effects in those organs. This method has significantly enhanced treatment outcomes for diseases such as Parkinson’s, cirrhosis, chronic kidney failure, and diabetes, as well as promoting vascular regeneration in conditions like erectile dysfunction.
③ Reduced Frequency and Time of Treatment
Arterial stem cell therapy has the advantage of providing stronger effects with fewer treatment sessions. While multiple sessions are often needed with venous injections, arterial stem cell therapy can achieve the same results with just one session. This means that it is a more efficient treatment method, reducing the overall number of sessions and time required. For example, the results of five venous stem cell treatments can be achieved in a single arterial stem cell session, thanks to the complete and loss-free delivery of stem cells to the target area.
④ Maximization of the Homing Effect
Stem cells have a homing effect, meaning they can recognize damaged areas and migrate to them to assist in regeneration. The homing effect refers to the phenomenon where stem cells find injured or inflamed tissue and promote regeneration at the site. This means that stem cells can recognize the damaged area in the body and move to it to help with treatment and recovery. This effect is one of the key characteristics of arterial stem cell therapy, as it allows stem cells to reach the precise location where they are needed in regenerative medicine.
Arterial injection further maximizes the homing effect. When stem cells are delivered through arteries, they move in an oxygen- and nutrient-rich environment, which enhances their ability to regenerate damaged tissues. As a result, the speed of treatment and recovery can be greatly accelerated.
Thus, arterial stem cell therapy is far more effective than venous injection in terms of stem cell delivery efficiency, concentration control, reduced treatment frequency, and maximization of the homing effect. This presents new possibilities in the treatment of various intractable diseases and regenerative medicine, offering a highly beneficial method for patients seeking fast and powerful therapeutic effects.

Advancement of Arterial Stem Cell Therapy and Future Prospects
① Advancement of Arterial Stem Cell Therapy
Stem cell therapy has made steady progress over the past few decades, playing a crucial role in regenerative medicine. Specifically, arterial stem cell therapy has emerged as an innovative treatment method, where stem cells are directly injected through the arteries, delivering fresh blood to damaged tissues and maximizing the effect of the stem cells. While traditional venous stem cell injections led to most of the cells being filtered out in the lungs, arterial injections ensure that 100% of the stem cells reach the desired organs, improving both efficiency and success rates. This advancement, based on successful clinical outcomes, has gradually expanded the range of applications for stem cell therapy.
Arterial stem cell therapy is particularly distinguished by its ability to deliver high concentrations of stem cells directly to damaged areas in conditions such as heart disease, Parkinson’s disease, chronic kidney failure, and erectile dysfunction, thereby significantly enhancing the treatment effect.
② Technological Advances and Precision Improvement in Treatment
The most crucial factors in stem cell therapy are stem cell activation and precise delivery. Recently, arterial stem cell therapy has developed by utilizing advanced imaging equipment and precise injection techniques to selectively administer stem cells to specific organs or areas. For example, arterial procedures using angiography and catheters allow the precise delivery of high concentrations of stem cells to the necessary areas. This technological advancement has greatly improved the safety and efficiency of the procedure, while also reducing treatment time. Furthermore, this precise therapy allows a single treatment to achieve the same effects as multiple previous treatments, significantly reducing the patient’s overall treatment time.
③ Expansion of Applications for Arterial Stem Cell Therapy
Initially, arterial stem cell therapy was primarily focused on treating cardiovascular diseases and erectile dysfunction. However, its range of applications has recently expanded to include neurological disorders, cirrhosis, diabetes, and more. Particularly in the treatment of neurological disorders like Parkinson’s disease, arterial stem cell therapy has proven highly effective in promoting the regeneration of damaged nerve cells by directly injecting high concentrations of stem cells through the cerebral arteries. Positive results have also been observed in chronic kidney failure treatments, where stem cells are injected into the renal artery to help restore kidney function. Thus, arterial stem cell therapy presents new possibilities for treating diseases that traditional methods have failed to resolve.
④ Future Prospects: The Core of Regenerative Medicine
The development of arterial stem cell therapy is expected to extend beyond disease treatment, with potential applications in anti-aging, cosmetic treatments, and other fields. In anti-aging research, arterial stem cells have shown promise in enhancing cell regeneration and slowing the body’s aging process. In the future, personalized stem cell treatments tailored to the patient’s genetics and health conditions are expected to emerge. These customized treatments will be optimized to deliver stem cells precisely where they are needed, offering more precise and safer treatment outcomes.

Although both arterial and venous stem cell therapies use the same stem cells, the method of injection leads to dramatically different results. Venous therapy sees a significant amount of stem cells lost in the lungs, limiting its effectiveness, while arterial therapy delivers 100% of the stem cells to the damaged organ, resulting in powerful regenerative effects. Additionally, arterial stem cell therapy is much more efficient in terms of treatment frequency, time, and cost.
