Understanding the condition
Understanding the condition and our regenerative approach
Osteoarthritis gradually wears down the smooth hyaline cartilage cushion inside weight-bearing and functional joints—including the knee, hip, shoulder, ankle, and small joints—turning everyday activities like walking, climbing stairs, reaching overhead, or gripping objects into sources of chronic aching and stiffness. Far from simple passive wear-and-tear, osteoarthritis is an active biological disease in which stressed cartilage cells (chondrocytes) and inflamed synovial lining cells overproduce matrix-digesting enzymes (MMPs and aggrecanases) and pro-inflammatory cytokines, while the underlying subchondral bone develops micro-edema and sclerosis under heightened mechanical load. As cartilage matrix thins and synovial lubrication deteriorates, joints lose their frictionless glide and surrounding tendons and capsules become chronically strained.
Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) and WJ-MSC-derived exosomes work directly inside osteoarthritic joint cavities and systemic pathways to calm synovial inflammation, protect surviving chondrocytes, and support extracellular matrix homeostasis. Once delivered, WJ-MSCs and their nanoscale exosomes downregulate inflammatory cytokines such as TNF-α, IL-1β, and IL-6 while shifting synovial macrophages from a cartilage-destructive M1 phenotype toward a reparative, anti-inflammatory M2 state. Simultaneously, they release chondroprotective and angiogenic growth factors—including TGF-β, IGF-1, VEGF, and tissue inhibitors of metalloproteinases (TIMPs)—while exosomal microRNAs and proteins penetrate dense hyaline cartilage to suppress catabolic enzyme activity, shield chondrocytes from oxidative apoptosis, and support subchondral microcirculation.
At our Istanbul regenerative medicine clinic led by Uzm. Dr. Cihan Bolat, we evaluate your weight-bearing X-rays and MRI scans for each affected joint to determine its exact Kellgren-Lawrence grade, anatomical depth, and biomechanical alignment. Using these diagnostic findings, our team designs a personalized protocol centered on real-time ultrasound-guided intra-articular WJ-MSC and exosome injections tailored to each target joint, paired with intravenous WJ-MSC and exosome support when multi-joint osteoarthritis is present. By restoring a calmer, growth-factor-rich joint microenvironment, our goal is to ease daily pain and morning stiffness, improve range of motion, and help you stay active and independent.

What happens inside the body
Key biological processes and therapeutic targets
Far from simple passive wear-and-tear, osteoarthritis is an active biological process involving chondrocyte stress, matrix-degrading enzymes, synovial membrane inflammation, and subchondral bone remodeling.
What our protocol aims to support
- Modulating intra-articular inflammatory cytokines: Ultrasound-guided WJ-MSC and exosome injections aim to calm synovial irritation and shift the joint microenvironment toward biological balance.
- Supporting cartilage matrix & chondrocyte signaling: Paracrine growth factors and exosomal cargo aim to nourish surviving chondrocytes and counteract catabolic matrix breakdown.
- Restoring smoother joint motion & daily activity tolerance: By reducing intra-articular friction and inflammatory aching, the protocol aims to support comfortable walking, reaching, and functional independence.
- Coordinated with biomechanical rehab & home care: Every protocol in Istanbul is designed to complement joint-strengthening physical therapy, weight and load optimization, and your ongoing medical care at home.
- 01
Enzymatic proteoglycan & collagen matrix loss
Healthy joint motion depends on resilient hyaline cartilage whose extracellular matrix is built from type II collagen networks and water-retaining aggrecan proteoglycans. In osteoarthritis, mechanical and inflammatory stress causes chondrocytes and synoviocytes to overexpress matrix metalloproteinases (MMP-13) and aggrecanases (ADAMTS-4/5) that erode this smooth gliding surface. Intra-articular WJ-MSCs and WJ-MSC exosomes counter this catabolic cascade by releasing tissue inhibitors of metalloproteinases (TIMPs) alongside anabolic factors such as TGF-β and IGF-1. At the same time, nanoscale exosomes penetrate the cartilage matrix to transfer microRNAs that silence matrix-degrading pathways and protect chondrocytes from oxidative cell death. This targeted support helps preserve surviving cartilage architecture across weight-bearing and functional joints.
- 02
Low-grade chronic synovitis
Microscopic cartilage wear particles continuously stimulate macrophages and synoviocytes in the joint lining, driving chronic low-grade synovitis across osteoarthritic hips, knees, shoulders, and ankles. Activated synovial cells release TNF-α, IL-1β, IL-6, and pain-sensitizing prostaglandins that degrade synovial fluid viscosity and cause morning stiffness and activity-related swelling. Delivered into the joint space under ultrasound guidance, WJ-MSCs and exosomes secrete IL-10 and TGF-β to reprogram synovial macrophages from a pro-inflammatory M1 phenotype into a tissue-healing M2 state. Exosomal proteins and microRNAs further quiet inflammatory signaling within synoviocytes. Calming this synovial irritation helps restore smoother joint lubrication and reduces daily aching.
- 03
Subchondral bone remodeling & micro-stress
As articular cartilage thins, mechanical forces concentrate sharply on the underlying subchondral bone plate, triggering abnormal bone sclerosis, peripheral osteophytes, microvascular ischemia, and painful bone marrow edema lesions. Inflammatory cross-talk across micro-channels between the subchondral bone and deep cartilage further accelerates joint degeneration and causes deep throbbing pain during weight-bearing. WJ-MSCs and WJ-MSC exosomes release angiogenic and osteo-modulatory growth factors—including VEGF, IGF-1, and TGF-β—that support local microvascular blood flow and healthier subchondral bone remodeling. Vesicular signaling also helps dampen inflammatory mediators at the osteochondral junction. Supporting subchondral microcirculation and bone homeostasis helps ease deep joint discomfort during standing and walking.
- 04
Periarticular capsule & tendon compensation
Osteoarthritis is a whole-joint condition in which altered joint mechanics and chronic inflammation lead to capsular fibrosis, ligament strain, and compensatory overload of surrounding tendons and stabilizing muscles. Whether in the hip flexors, rotator cuff tendons, or knee extensors, this periarticular strain restricts range of motion and increases energy expenditure during movement. Intra-articular and peritendinous paracrine signals from WJ-MSCs and exosomes—such as IGF-1, TGF-β, and anti-fibrotic microRNAs—help calm capsular inflammation and support healthier collagen elasticity. By reducing intra-articular pain and stiffness, treatment also relieves arthrogenic muscle inhibition around the joint. This enables patients to engage more comfortably in targeted physical therapy to restore balanced joint biomechanics.
Why regenerative medicine is investigated
Scientific rationale for Wharton's jelly MSCs and exosomes
Biological Repair Rationale for Active Osteoarthritic Cartilage Loss
Osteoarthritis progresses when biochemical inflammation inside the synovial cavity outpaces the slow natural repair capacity of avascular articular cartilage. Pro-inflammatory cytokines (IL-1β, TNF-α) stimulate chondrocytes to release MMP-13 and aggrecanases that digest the type II collagen and proteoglycan framework. Regenerative therapy intervenes directly in this biochemical loop by suppressing catabolic enzymes and calming synovial irritation. Creating an anti-inflammatory, trophic joint microenvironment helps surviving chondrocytes preserve remaining cartilage matrix.
Synergistic Action of Wharton's Jelly MSCs & Exosomes
Wharton's jelly-derived MSCs (WJ-MSCs) and WJ-MSC exosomes work together through complementary paracrine, immunomodulatory, and vesicular pathways inside the joint capsule. Live WJ-MSCs secrete anti-inflammatory cytokines (IL-10, TGF-β), anabolic growth factors (IGF-1), and natural MMP inhibitors (TIMPs) that polarize synovial macrophages from destructive M1 to reparative M2 states. Concurrently, concentrated nanoscale exosomes diffuse deep into dense cartilage zones to deliver regulatory microRNAs and protective proteins directly into stressed chondrocytes. This combined biological action supports both synovial fluid lubrication and extracellular matrix stability.
Joint-Specific Imaging Review & Ultrasound Precision in Istanbul
Because the knee, hip, glenohumeral shoulder, and ankle differ in joint depth, capsule volume, and mechanical loading, Uzm. Dr. Cihan Bolat evaluates the imaging for every affected joint before travel. We allocate customized WJ-MSC cell counts and exosome doses to each specific joint and perform every intra-articular injection under continuous real-time ultrasound guidance. When osteoarthritis affects multiple joints simultaneously, we combine targeted intra-articular injections with intravenous WJ-MSC and exosome infusions. This individualized planning ensures anatomical precision and realistic functional goals.
Our treatment approach & administration routes
How our proposed Wharton's jelly MSC and exosome protocols work
- 01
Ultrasound-Guided Intra-Articular WJ-MSC Injection
This core route delivers Wharton's jelly mesenchymal stem cells (WJ-MSCs) directly into the target joint cavity under continuous, real-time ultrasound visualization. Real-time ultrasound is essential for navigating deep or narrowed joint spaces—such as the hip joint capsule, glenohumeral shoulder joint, tibiotalar ankle joint, or knee compartments—with millimeter accuracy. Once inside the synovial cavity, WJ-MSCs secrete anti-inflammatory cytokines (IL-10, TGF-β), anabolic growth factors (IGF-1), and natural MMP inhibitors (TIMPs) that polarize macrophages to the reparative M2 phenotype and protect resident chondrocytes. It is chosen to provide sustained, localized paracrine repair directly where cartilage and synovium are stressed.

- 02
Ultrasound-Guided Intra-Articular Exosome Administration
Administered into the target joint space under ultrasound guidance alongside WJ-MSCs, concentrated WJ-MSC-derived exosomes deliver billions of nanoscale extracellular vesicles rich in chondroprotective proteins and regulatory microRNAs. Their nanoscale diameter allows them to diffuse rapidly through synovial fluid and penetrate dense, avascular hyaline cartilage to reach stressed chondrocytes directly. Inside the cells, exosomal cargo downregulates catabolic MMP-13 and aggrecanase pathways, reduces mitochondrial oxidative stress, and supports extracellular matrix maintenance. Pairing intra-articular exosomes with live WJ-MSCs ensures both immediate molecular signaling and prolonged cellular trophic support inside the treated joint.

- 03
Intravenous WJ-MSCs & Exosomes (For Multi-Joint Osteoarthritis)
When osteoarthritis affects multiple joints simultaneously—such as bilateral knees, hips, hands, and spine—or is accompanied by systemic low-grade metabolic inflammation, intravenous infusion of WJ-MSCs and exosomes is combined with targeted intra-articular injections. Circulating cells and vesicles downregulate systemic pro-inflammatory cytokines (TNF-α, IL-1β, IL-6), promote regulatory T-cell balance, and support microvascular endothelial health across subchondral bone beds. This systemic biological support helps calm generalized morning stiffness and reinforces the local reparative environment in every treated joint. Uzm. Dr. Cihan Bolat customizes the balance between local joint doses and intravenous infusion based on your complete imaging review.

What we aim to achieve
Therapeutic objectives and functional outcomes we track
Before treatment in Istanbul, our physicians establish your clinical baseline and define realistic biological and functional objectives to track during follow-up.
- 01
Joint-Specific Pain & Function Scales (WOMAC, KOOS, HOOS & QuickDASH)
By calming synovial TNF-α and IL-1β signaling and protecting cartilage matrix with TIMPs and TGF-β, our protocol aims to improve scores on validated joint-specific scales for the knee, hip, shoulder, or hand. We track these standardized questionnaires across follow-up to measure meaningful daily relief.
- 02
Active Range of Motion & Shorter Morning Stiffness
Shifting synovial macrophages toward a reparative M2 phenotype and easing capsular inflammation helps restore smoother joint gliding after rest. In daily life, patients notice briefer morning stiffness and easier bending, rotation, or overhead reaching.
- 03
Walking Endurance, Stair Mobility & Upper-Limb Comfort
Supporting subchondral bone microcirculation and chondrocyte resilience helps weight-bearing joints tolerate longer walks and stairs, while helping upper-limb joints perform lifting, dressing, and gripping tasks with less aching. These functional improvements directly support everyday independence.
- 04
Reduced Joint Swelling & Stronger Rehabilitation Progress
Quieting chronic synovitis decreases recurring joint effusion and lifts pain-related muscle inhibition around the affected joint. This allows you to participate more comfortably in physical therapy to build long-term muscular stability around your joints.
