- Psoriatic arthritis is driven by an overactive immune system that targets skin, joints and tendons.
- Umbilical cord stem cells are studied to rebalance that response rather than switch it off.
- Human studies in psoriasis and rheumatoid arthritis have shown encouraging changes in immune markers and disease activity.
With psoriatic arthritis, your body seems to be running two complaints at once. The skin flares, a whole finger or toe swells up (doctors call it dactylitis), the heel hurts where the tendon attaches, and mornings start stiff.
Maybe your biologic worked beautifully for two years and then quietly stopped. Maybe you want more options. Either way, you are wondering whether there is another way to calm the immune system, and whether stem cells are part of that conversation.
Why does psoriatic arthritis hit skin and joints at the same time?
Because the problem isn’t really in the skin or the joint. It is in the immune system, which sends inflammatory messengers, such as IL-17, IL-23 and TNF, to both places.
That is why doctors call PsA a systemic disease. It can involve the joints, the spine, the spots where tendons attach to bone, the skin and the nails, and it is linked with heart and metabolic health too.
What do today’s treatments do?
Anti-inflammatories ease the pain. Disease-modifying drugs and biologics block specific immune signals, and for many people they work well.
But a biologic blocks one or two messengers. It is a bit like muting one loud guest at a party while the rest of the room keeps shouting.
What would stem cells do differently?
Mesenchymal stem cells, or MSCs, from umbilical cord tissue don’t block a single molecule. In studies, they shift the immune system’s balance: fewer aggressive Th17 cells, more regulatory T cells, the ones whose job is to say “that’s enough.”
Why cord tissue? Reviews comparing sources found that cord MSCs multiply readily and have strong calming effects on immune cells, and because they come from donated cords, nothing has to be collected from your own body.
The aim is to rebalance the immune response, not to shut it down. That difference matters, because you still need an immune system that fights infections.
What does the evidence show so far?
For skin psoriasis, there is a small human trial. Seventeen patients received umbilical cord MSCs; about half improved their skin score by at least 40%, with no obvious side effects, and responders showed more regulatory T cells and fewer Th17 cells.
For joints, the closest data come from rheumatoid arthritis. In a study of 172 patients whose medications were not enough, adding cord MSCs lowered inflammatory markers and disease activity for three to six months.
Psoriatic arthritis sits between psoriasis and rheumatoid arthritis, and research in both points in an encouraging direction. Research in psoriatic arthritis itself is growing.
Who might consider it?
- You have a confirmed diagnosis and a rheumatologist who follows you.
- You want more control over your disease alongside your medication.
- You can share recent blood work and your treatment history, so the rheumatologist sees the full picture.
- You want an option studied alongside standard treatment.
- Keep your current treatment and your rheumatologist; never stop medication on your own.
- Send your blood work and history on WhatsApp for an evaluation by the rheumatologist, with no commitment.
- Your plan and price come in writing before you travel.
Umbilical cord MSCs have been tested in small human studies of psoriasis and in larger studies of rheumatoid arthritis, with encouraging changes in immune markers and disease activity and a good safety record. Research in psoriatic arthritis itself is growing.

Questions
Can stem cells treat psoriatic arthritis?
They are studied for it. Human studies in psoriasis and rheumatoid arthritis are encouraging, and research is growing. The rheumatologist reviews your case first, so your plan is designed for you.
Do I have to stop my biologic?
No decision about your medication is made without your rheumatologist. The specialist coordinates with your treatment; you never stop anything on your own.
How long is the trip?
The intravenous protocol takes three days in Medellín. Three nights at the Marriott Hotel in the same building and your transfers can be added to your plan, and your coordinator sends that price in writing.
How do you make sure it is safe for me?
Every IV protocol starts with cancer markers, for your safety, and your full history is reviewed in your online consultation.
Is stem cell therapy approved by the FDA?
Stem cell therapy is not approved by the FDA, but in Colombia it is legal.
