Stem Cell Therapy for Crohn's Disease in Istanbul
How our medical team reads your endoscopy, enterography and biologic history, what an infusion plan involves alongside gastroenterology care, and how to begin.
Understanding Crohn's Disease
Crohn's disease is inflammation that runs through the full thickness of the bowel wall - transmural inflammation - and it can appear anywhere from mouth to anus, most often where the small intestine meets the colon. Your reports describe both where it sits and how it behaves: ileal, ileocolonic or colonic disease, with behaviour recorded as inflammatory, stricturing or penetrating, and perianal disease noted separately. Patients usually meet the Montreal classification, skip lesions, terminal ileitis, calprotectin, fistula and stricture on paper before anyone sits down and explains them. In daily life it is cramping an hour after eating and a growing wariness of food, urgency that maps the day around bathrooms, nights broken by pain, weight that will not stay on, and a fatigue that lingers long after a flare has been called settled. Where a stricture has narrowed the bowel it brings bloating, loud cramps and vomiting; where a fistula has formed it brings drainage, pain and a course of its own.
What an MSC-based plan is aimed at in Crohn's is the immune activation driving inflammation through the bowel wall. Biologic drugs work by blocking one specific messenger or pathway - TNF, the interleukin-12 and interleukin-23 route, or the traffic of immune cells into the gut - and for many people that is exactly the right instrument. Mesenchymal stromal cells are studied from a different angle: their influence on immune behaviour as a whole, known as immunomodulation, together with the signals they release into inflamed tissue, called paracrine signalling. Our program works with MSCs from Wharton's jelly, the gelatinous tissue inside an umbilical cord donated after a healthy birth with written maternal consent; the low-immunogenicity profile of this source is one reason it is studied for use between unrelated people, and each batch is characterised and release-tested before use. In our Crohn's plans the route is an intravenous infusion - fistula work, where cells are positioned surgically around a perianal tract, belongs to a different pathway with its own research, and our inflammatory bowel disease page sets that out alongside ulcerative colitis. One point our team is exact about: a stricture that has turned fibrous is scar tissue, and the research does not describe dissolving it.
Our medical team reads the file the way your gastroenterologist does: disease location and behaviour, the most recent ileocolonoscopy with biopsy results, MR or CT enterography for the small bowel and for any fistula or abscess, faecal calprotectin and CRP, albumin, haemoglobin, iron, B12 where the terminal ileum is inflamed or has been resected, and vitamin D. Your biologic history carries as much weight as any of that - which agents, in what order, whether a drug never worked or worked and then stopped, drug levels and antibodies where they were measured, and the reason each was discontinued. Surgical history is reviewed in the same detail: resections and how much bowel remains, strictureplasty, abscess drainage, setons and stoma status, along with the tuberculosis and hepatitis screening that belongs before any immune-directed treatment. Gastroenterology care continues throughout, and where treatment is appropriate the goals may centre on how heavily symptoms weigh on an ordinary day, on nutrition and weight, on the fatigue that sits between flares, and on the calprotectin trend your own team already follows. Send your last colonoscopy and enterography reports with your biologic history, and our medical team will tell you whether a case review is worth opening now or after your next gastroenterology appointment.
How Crohn's Disease Can Affect Daily Life
Symptoms, severity and progression vary from person to person. Our medical team uses this kind of detail as context for your case review; it is not a diagnostic checklist. Diagnosis, and any change in your symptoms, belong with the clinician who knows your medical history.
- Cramping abdominal pain, often in the lower right abdomen and worse after eating
- Diarrhoea, urgency and nights broken by symptoms
- Weight loss, poor appetite and iron or B12 deficiency
- Fatigue that persists between flares
- Perianal pain or drainage, or the bloating and vomiting of a narrowed segment
Inflammation through the whole wall
Crohn's disease is defined by how deep the inflammation goes, not only by where it sits. This visual shows the full thickness of the bowel wall, which is what makes strictures and fistulae possible.

Clinical context

Microscopic research viewIllustrative detail
- Transmural, and patchy
- Inflammation crosses the full wall thickness and skips along the bowel, leaving healthy segments between affected ones.
- Strictures and fistulae
- Repeated deep inflammation can narrow a segment or tunnel through the wall, and both change what treatment is appropriate.
- Alongside your gastroenterology care
- Biologics, immunomodulators, surgical history and current disease activity are read together before anything is proposed.
Why Regenerative Medicine Is Being Studied in Crohn's
These are the biological mechanisms researchers are investigating. A mechanism is a reason to study a treatment, not a promise of benefit for an individual patient. Our medical team will explain how much of this research applies to your own diagnosis.
- The route in our Crohn's plans is an intravenous infusion, scheduled around your biologic dosing rather than across it
- MSCs are studied for their influence on immune behaviour as a whole, known as immunomodulation, rather than for blocking one named messenger
- They release signals into inflamed tissue - paracrine signalling - which is the mechanism most current MSC research centres on
- Transmural inflammation and fibrosis are different problems: an established fibrotic stricture is scar tissue, and dilatation or surgery is the conversation there
- Fistula work answers a different question from an infusion - cells positioned surgically around a perianal tract sit on their own pathway, and our team names which of the two it is proposing
- Calprotectin, CRP and symptom scores are recorded before treatment, so your gastroenterologist and our team are reading the same numbers afterwards

Your case review
How Our Medical Team Reviews Your Case
Your review starts with the confirmed diagnosis, recent reports and imaging, current treatment, medical history, and the outcome that matters most to you. Not everyone is suitable for regenerative medicine, and our team will say so when the care you already receive is the better route.
- A confirmed Crohn's diagnosis with location and behaviour documented - ileal, ileocolonic or colonic, and inflammatory, stricturing or penetrating
- Recent ileocolonoscopy with biopsy results, and MR or CT enterography covering the small bowel
- Faecal calprotectin, CRP, albumin, haemoglobin, ferritin and B12, with the dates they were taken
- A complete biologic and immunomodulator history: which agents were used, whether each failed from the start or stopped working later, and why it was discontinued
- Surgical history in detail - resections and remaining bowel length, strictureplasty, setons, abscess drainage and stoma status
- No active severe flare, no untreated abscess and no obstructing stricture, confirmed by your gastroenterologist before travel is discussed
How Treatment for Crohn's Is Planned at Our Istanbul Clinic
The path international patients follow with us, from the first review of your records to follow-up after you return home. The exact steps depend on what your medical review finds.
Send your medical records
Recent reports, imaging, your current medication, and what you hope treatment will help with. It lets our medical team make the review specific to you.
Start your case reviewSend your medical records
Your case review starts with the confirmed diagnosis, recent reports and imaging, current medications, previous procedures and the outcomes that matter most to you. Everything can be sent digitally from home, long before travel is discussed.
Case review by our medical team
Our medical team reads the file against your diagnosis, disease stage, imaging, laboratory results, current treatment and any contraindications, then decides whether regenerative medicine is appropriate for you and which goals are realistic to discuss.
Your written treatment plan
When treatment is appropriate, you receive the plan in writing: the cell material and how it is prepared, the dose, the route of administration, the number of sessions, the monitoring involved and an itemized cost with no assumed extras.
Your treatment in Istanbul
On arrival our team repeats the checks that matter for your case, confirms the plan with you, and carries out treatment under medical supervision with an observation period afterwards. Your coordinator handles scheduling, timings and what each day involves.
Follow-up and monitoring
Before you fly home we agree what will be measured, when it will be reviewed and how to reach us. Follow-up continues remotely and can be shared with your own doctors, so your treatment plan and your local care stay aligned.
Your treatment plan
What Our Medical Team Explains Before You Decide
"Stem cells" and "exosomes" name a category, not a specific product. What matters in your plan is the source of the material, how it was prepared, the route and the dose, the clinical setting, and why you were considered suitable. Our medical team sets each of those out for the treatment being proposed to you.
We plan treatment alongside the care you already receive, so keep your own clinician involved and record a clear baseline before you travel. For the practical side, read the Istanbul treatment trip guide and the cost guide, then ask us for an itemized estimate.
- Which published research applies to your diagnosis and to the route we propose.
- Where the biological material comes from, how it is prepared, and how it is documented.
- The possible side effects and the contraindications that apply to your procedure.
- Which functional outcome is measured before treatment and again at follow-up.
- How treatment sits alongside your existing care, including the option of not treating.
- Who to contact about follow-up, or about a complication, once you are home.
- What your estimate includes and excludes, and what is due before you travel.

Crohn's Disease: Questions Patients Ask Us
What does Crohn's disease stem cell therapy cost in Istanbul, Turkey?
The gastroenterology review, laboratory work, the number of infusions and the monitoring during your stay are quoted line by line rather than as a single package figure, since the case review decides which of them your file actually needs. Our patient coordination team confirms the itemized plan in writing before flights are booked, and states the position in advance if disease activity means treatment has to be deferred after you arrive.
Is there evidence that stem cell therapy works for Crohn's disease?
Crohn's has one of the longer research relationships with these cells of any condition we treat, and the immune rationale behind it is one our medical team is confident explaining. It runs in two directions that should never be blurred together: local placement around perianal fistulas, and systemic infusion aimed at immune signalling. Responses differ between patients, so your plan is written as goals with measurements attached - and what your calprotectin, CRP and symptom scores do afterwards is the answer that applies to you.
How long do international patients stay in Istanbul for Crohn's treatment?
Your written plan states it before you commit to flights: the assessment on arrival, the number of infusions, the observation after each one, and the checks our team repeats where there has been recent disease activity. Our patient coordination team confirms dates and daily timings in writing, and builds the schedule around bathroom access and travel comfort rather than pretending those do not matter.
Does this replace my biologic, or work alongside it?
Alongside it. Nothing in this plan is a reason to stop infliximab, adalimumab, ustekinumab, vedolizumab or an immunomodulator, and coming off a biologic that is holding your disease is how people lose remission - our medical team will not propose it, and will not proceed if you have stopped one in order to travel. What we do review is timing: when your last dose was given, when the next is due, your infection screening and your current disease activity, so the infusion is scheduled sensibly around all four. The plan is shared with your gastroenterologist so both sides are working from the same file.
Are Wharton's jelly stem cells used to treat Crohn's Disease in Istanbul?
Yes. Our regenerative medicine program works with mesenchymal stromal cells (MSCs) grown from Wharton's jelly, the gelatinous tissue inside the umbilical cord. It is donated after a healthy birth with written maternal consent, from tissue that would otherwise be discarded, so nothing is taken from mother or baby and none of the ethical questions attached to embryonic sources arise. Because these cells expand readily in culture, a batch is characterised and release-tested before it reaches anyone. Your written plan names the material, how it is prepared, the dose, the route of administration and the schedule, and our medical team explains why each of those was chosen for your case.
Why use donor cells from Wharton's jelly rather than my own cells for Crohn's Disease?
Wharton's jelly is a young, perinatal tissue rather than an adult one, so the starting material does not carry the age or the health history of the person being treated, and nothing has to be harvested from you on the day. These cells also have a low-immunogenicity profile, which is why this source is studied for use between unrelated people. Most of all, they are strong secretors: the signalling molecules MSCs release are the mechanism most current research centres on, and that is what a plan is built around.
How long do international patients stay in Istanbul for Crohn's Disease treatment?
The length of stay follows your plan: the route of administration, the number of sessions, the monitoring after each one, and any mobility or assistance you need. Our patient coordination team confirms appointment dates, daily timings and the expected length of the visit in writing before you book flights.
Is stem cell therapy for Crohn's Disease safe?
No medical procedure is free of risk. Our medical team screens for infection, bleeding risk, medication interactions and other contraindications before treatment, explains the risks specific to the route used in your plan, and monitors you during administration and afterwards. If something makes treatment unsafe for you, we say so instead of proceeding.
What can stem cell therapy realistically aim for in Crohn's Disease?
Goals are set with you and described as aims, not results. Regenerative medicine treatments are planned individually, responses vary between patients and no clinical outcome can be guaranteed. Your plan states what will be measured, when it will be reviewed, and how treatment sits alongside the care you already receive.
How do I start a Crohn's Disease case review from outside Turkey?
Send your confirmed diagnosis, recent reports and imaging, your current medication list, previous procedures and the goals that matter to you. Our medical team reviews them remotely and comes back with an assessment of whether treatment in Istanbul is appropriate for your case, and what the next step would be.
Medical Disclaimer: Information on this page is educational and is not personal medical advice. Regenerative medicine treatments are planned individually, responses vary and no clinical outcome can be guaranteed. Some of the approaches described remain investigational. Suitability is confirmed only after medical review, and treatment is planned alongside your existing care.
