Stem Cell IV Infusion: Effects on Reducing Inflammation and Three Study Cases

Unlike acute inflammation such as pneumonia or sepsis, where fever spikes, chronic inflammation is compared to smoke slowly leaking from inside a building. The embers of chronic inflammation are harder to extinguish with age, more visceral fat, lack of exercise, or irregular sleep. This chronic inflammation is a problem that affects the whole body, not just one place.

Dr. Kim stressed that these four effects do not operate separately but form one interconnected recovery process.

These four actions can be seen as a single, interconnected recovery process. Inflammation must subside for an overreacting immune response to stabilize, and damaged blood vessels and microcirculation must recover before tissue can come back to life. The previous videos covered the immune-regulating and angiogenic effects of stem cells, and this video discusses the anti-inflammatory effect, which can be called the starting point of the recovery process.

Acute inflammation is a normal and necessary response that sends blood and immune cells to a wound.

The problem arises when the fire of inflammation fails to go out when it should and keeps going. When inflammatory substances are secreted continuously, even healthy tissue is damaged and microcirculation worsens. Eventually a vicious cycle forms in which inflammation damages tissue and the damaged tissue calls up more inflammation. The chronic inflammation of focus today is not a big blaze like pneumonia or sepsis, but more like smoke slowly leaking from inside a building.

Chronic inflammation does not bring a building down right away, but over a long time it slowly deteriorates the wiring, walls, and ventilation, much like a building aging. The older you get, the more visceral fat you carry, and the less you exercise or the more irregular your sleep, the harder these inflammatory embers are to put out. This low-grade inflammation advances the disease quietly, so even if you feel no pain, your blood vessels and organs keep being exposed to mild inflammation inside your body.

If the problem is in one spot, such as a knee, the drug can be injected directly into the joint. But chronic inflammation is a problem of the whole body, not one place, because inflammatory substances circulating in the blood stimulate blood vessels and many organs at once. IV infusion puts cells directly into the bloodstream, so it takes the approach of calming the inflammatory environment of the whole body rather than a single site. The signaling molecules released by stem cells lower excess inflammatory substances and reduce ongoing damage to blood vessel walls.

When the embers of inflammation subside, they prevent damage to cells that are still healthy, and they create the foundation for the next stages of blood vessel repair and tissue regeneration. So anti-inflammation is not the end of treatment but the first step. Now we will look at the anti-inflammatory effect of stem cells through human studies. Chronic obstructive pulmonary disease (COPD) looks like a lung-only disease, but it is actually a condition in which body-wide low-grade inflammation overlaps with chronic inflammation of the lungs.

In 2013, at six medical centers in the United States, 62 patients with moderate to severe COPD received 100 million mesenchymal stem cells derived from another person's bone marrow, or a placebo, through IV infusion four times at one-month intervals. Overall, there was no clear difference in lung function, exercise capacity, or quality of life. However, in patients whose inflammatory markers were high from the start, CRP (C-reactive protein) dropped noticeably earlier after stem cell infusion.

In other words, people with low inflammatory markers saw little change, while people whose inflammation was raging from the start showed clear anti-inflammatory signals. Next, ulcerative colitis is a disease in which inflammation and ulcers of the colon lining recur.

Ulcerative colitis causes abdominal pain, diarrhea, and bloody stools as inflammation continues, and it breaks down the protective barrier of the intestine. In a 2024 study, 41 patients with moderate to severe disease who did not respond well to existing drugs received umbilical cord blood stem cells by IV. They received 1 million cells per kg of body weight, meaning 60 million cells for a 60 kg person, given twice at one-month intervals. Two months later, 73.2% showed a response with improved symptoms, and 41.5% achieved remission, with symptoms nearly gone.

Colonoscopy and tissue biopsy also showed reduced inflammation, and several inflammatory substances in the blood decreased as well. What is striking is that even with stem cells given by IV eight times, both intestinal and systemic inflammation improved together. This shows that the anti-inflammatory effect of IV infusion is not limited to blood test numbers but can lead to real easing of inflammation in organ tissue. Next, we look at sepsis, the most severe form of inflammation.

Sepsis is not simply bacteria in the blood. It is a life-threatening condition in which the body's response to infection becomes excessive, blood pressure falls, and several organs fail at once. The infection is a problem, but the severe systemic inflammation that arises in response to it burns your own organs along with it.

In a 2022 study, 10 patients with sepsis and septic shock received stem cells derived from another person's fat by IV five times alongside standard treatment. All 10 patients in the stem cell group survived to day 14, and the 28-day survival rate was 70%. The SOFA score, which combines the function of several organs, also improved clearly during treatment. Although there were only 10 patients, the fact that all of them survived the first 14 days despite being at very high risk of death on standard treatment alone makes the approach worth studying.

However, it must be made clear that the foundation of sepsis care is still rapid elimination of infection with antibiotics, fluids, and maintaining blood pressure. Stem cells are not a replacement for these treatments but an auxiliary approach being studied for whether they can reduce excessive systemic inflammation. The three studies introduced today differ in the intensity of inflammation. COPD is long-lasting, low-grade chronic inflammation, ulcerative colitis is chronic inflammation that actively progresses in one organ, and sepsis is the most extreme inflammation, spreading out of control across the whole body.

Its greater significance lies in breaking the vicious cycle in which inflammation keeps eroding tissue, preventing further organ damage, and creating an environment in which blood vessels and tissue can recover. Of course, an anti-inflammatory effect does not appear equally in every chronic disease.

Summarizing the key point in one sentence: the anti-inflammatory effect of stem cell IV infusion is not limited to relieving pain. It is the first step that lowers the embers of inflammation that keep burning in the body, prevents further damage to blood vessels and organs, and builds the foundation on which recovery can begin.

It is the first step that lowers the embers of inflammation that keep burning in the body, prevents further damage to blood vessels and organs, and builds the foundation on which recovery can begin. The next video will continue with tissue regeneration, the ultimate goal of stem cells. That was Dr. Kim Yeong-cheol of Kim Yeong-gam's Stem Cell Story. Thank you.
