Cellular Therapy and Stem Cellsfor Osteonecrosis (Avascular Necrosis) signify a transformative frontier in regenerative orthopedics, offering hope for patients facing progressive bone tissue death due to disrupted blood supply. AVN most commonly affects the femoral head, but it may involve the humerus, knees, or ankles—leading to joint collapse, chronic pain, and immobility. Traditional interventions such as core decompression, bisphosphonates, or total joint replacement often fall short of halting the underlying bone degradation, especially in early and intermediate stages. In contrast, Cellular Therapy and Stem Cells offer a novel approach: regenerating necrotic bone, revascularizing ischemic tissue, and modulating inflammatory responses at the molecular level.
Despite advances in orthopedic care, existing AVN therapies primarily address symptom control or mechanically delay joint destruction, without repairing the fundamental ischemic insult. The pathophysiology of AVN includes impaired angiogenesis, cellular apoptosis, and aberrant bone remodeling. Consequently, patients frequently experience worsening joint instability and functional decline. The unmet need for biologically restorative treatment underlines the importance of regenerative strategies that can stimulate osteogenesis, enhance perfusion, and promote tissue integration at the site of necrosis.
At the intersection of orthopedics and regenerative medicine lies the promise of Cellular Therapy and Stem Cellsfor Osteonecrosis (Avascular Necrosis)—where mesenchymal stem cells (MSCs), bone marrow aspirate concentrate (BMAC), and exosomes are being employed to actively restore bone vitality. Envision a future where early-stage AVN can be reversed before surgical intervention becomes necessary. This paradigm shift redefines the therapeutic trajectory by harnessing the body’s own reparative potential. Join us at DrStemCellsThailand as we advance cellular orthobiologics into clinical practice—transforming the lives of those afflicted with osteonecrosis [1-3].
2. Genetic Insights: Personalized DNA Testing for Osteonecrosis Risk Assessment Before Cellular Therapy and Stem Cells for Avascular Necrosis
At DRSCT’s Genomic and Orthobiologic Precision Unit, we provide comprehensive DNA testing to assess genetic susceptibility to Avascular Necrosis (AVN), particularly in individuals with a history of corticosteroid use, alcohol abuse, or hematologic disorders. Our testing targets key polymorphisms and genetic variants associated with impaired angiogenesis, thrombophilia, lipid metabolism, and osteoblast dysfunction. These include variations in genes such as:
VEGFA (vascular endothelial growth factor A) – involved in angiogenesis and tissue perfusion.
eNOS (endothelial nitric oxide synthase) – related to vascular tone and bone circulation.
MTHFR (methylenetetrahydrofolate reductase) – associated with homocysteine metabolism and thrombotic risk.
COL1A1/COL1A2 – collagen synthesis genes linked to bone matrix integrity.
ABCB1 and CYP3A5 – influencing steroid metabolism and predisposition to steroid-induced AVN.
By analyzing these and other genomic profiles, we can identify individuals at high risk for AVN development or progression. This information guides a personalized roadmap for preventive measures, including early lifestyle interventions, reduction of corticosteroid exposure, and the initiation of targeted regenerative protocols. Most importantly, this precision medicine approach allows us to customize cellular therapy plans—selecting the optimal source, type, and route of stem cell administration based on each patient’s unique molecular architecture.
With early identification of genetic predispositions, we can transform the narrative of osteonecrosis from reactive treatment to proactive regeneration—paving the way for earlier, more effective, and tailored interventions [1-3].
3. Understanding the Pathogenesis of Osteonecrosis: A Detailed Overview
Osteonecrosis (Avascular Necrosis) is a debilitating skeletal disorder characterized by the progressive death of bone tissue due to impaired blood supply. While AVN can affect multiple joints, the femoral head is most commonly involved. The condition is multifactorial, involving genetic, mechanical, and biochemical contributors that ultimately disrupt the vascular integrity and structural architecture of bone.
Bone Ischemia and Cell Death
Vascular Disruption and Hypoxia
Intravascular Coagulation: Hypercoagulable states, often due to corticosteroids or thrombophilic gene mutations (e.g., Factor V Leiden), lead to microthrombi formation within bone vessels.
Fat Embolism: In alcohol-induced or corticosteroid-induced AVN, lipid emboli obstruct the microcirculation, impairing perfusion to subchondral bone.
Reduced Angiogenesis: Downregulation of VEGF and other pro-angiogenic factors compromises the revascularization process [1-3].
Osteocyte Apoptosis and Necrosis
Mitochondrial Dysfunction: Ischemia leads to ATP depletion in osteoblasts and osteocytes, triggering apoptotic pathways.
Oxidative Stress: Increased reactive oxygen species (ROS) contribute to bone marrow stromal cell damage and further cell death.
Inflammatory and Remodeling Dysregulation
Pro-Inflammatory Microenvironment
Cytokine Cascade: TNF-α, IL-6, and other inflammatory mediators exacerbate vascular injury and bone resorption.
Matrix Metalloproteinases (MMPs): Elevated MMP activity disrupts bone matrix integrity and accelerates necrosis.
Bone Remodeling Imbalance
Suppressed Osteogenesis: Impaired differentiation of mesenchymal stem cells into osteoblasts slows bone repair.
Subchondral Fracture Formation: Loss of structural support leads to microfractures under normal load-bearing.
Articular Cartilage Damage: Collapsed bone disrupts the cartilage-bone interface, accelerating degenerative joint disease.
Secondary Osteoarthritis
Joint Space Narrowing and Pain: Progressive cartilage degeneration results in chronic joint pain, stiffness, and reduced mobility.
Functional Impairment: Patients often progress to require arthroplasty if not treated in early stages.
Cellular Therapy and Stem Cellsfor Osteonecrosis (Avascular Necrosis) offer a compelling solution to interrupt these pathological cascades. By delivering osteogenic, angiogenic, and immunomodulatory cells directly to necrotic zones, these therapies aim to re-establish vascularization, support bone regeneration, and modulate the inflammatory microenvironment. This integrated strategy has the potential not only to halt progression but also to reverse osteonecrotic changes, offering renewed hope for joint preservation and patient mobility [1-3].
4. Causes of Osteonecrosis (Avascular Necrosis): Unraveling the Complexities of Bone Degeneration
Osteonecrosis (also known as avascular necrosis or ON) is a debilitating bone disorder caused by the interruption of blood supply to bone tissue, leading to cellular death, structural collapse, and eventual joint dysfunction. While the femoral head is most commonly affected, osteonecrosis can compromise multiple joints. The pathogenesis of ON involves a multifactorial network of vascular impairment, genetic susceptibility, and cellular dysregulation, including:
Vascular Compromise and Ischemia-Induced Necrosis The hallmark of osteonecrosis is compromised microvascular circulation within bone marrow and trabecular bone. This disruption may result from trauma, corticosteroid use, alcoholism, or thrombophilic conditions.
Microvascular Occlusion: Ischemic injury leads to osteocyte and bone marrow cell death due to prolonged hypoxia.
Endothelial Dysfunction: Reduced nitric oxide bioavailability and increased endothelin-1 promote vasoconstriction and impede bone perfusion.
Cellular Apoptosis and Bone Marrow Dysfunction
Osteoblast and Osteocyte Apoptosis: Hypoxia-induced oxidative stress triggers programmed cell death, impairing bone remodeling.
Bone Marrow Edema: Ischemia leads to marrow expansion and inflammation, further compressing microvessels and perpetuating necrosis.
Lipid Dysregulation and Intramedullary Pressure
Fat Embolism and Lipocyte Hypertrophy: Corticosteroids and alcohol use induce lipid accumulation in bone marrow, increasing intramedullary pressure and collapsing vascular channels.
Adipogenesis Over Osteogenesis: Dysregulated mesenchymal differentiation favors fat cell formation over osteoblast lineage commitment.
Thrombophilic and Coagulopathic Factors
Genetic Mutations in Coagulation Pathways: Mutations in MTHFR, Factor V Leiden, and Protein C/S deficiencies increase the risk of microthrombi formation.
Fibrinolytic Dysfunction: Impaired fibrin breakdown contributes to persistent vascular obstruction and hypoxia.
Genetic and Epigenetic Vulnerabilities
Polymorphisms in VEGF, eNOS, and COL2A1 have been implicated in ON susceptibility, affecting angiogenesis, nitric oxide synthesis, and collagen stability.
Epigenetic Regulation: Methylation of osteogenic genes and histone modifications play emerging roles in ON progression.
Given the complex and often silent progression of osteonecrosis, early detection and innovative therapies targeting these multifactorial mechanisms—especially through regenerative strategies like stem cells—are essential for preserving joint function and quality of life [4-7].
5. Challenges in Conventional Treatment for Osteonecrosis (Avascular Necrosis): Technical Hurdles and Limitations
Despite advances in orthopedic surgery and pharmacotherapy, the conventional management of osteonecrosis remains limited by several technical and biological constraints. The goal of preserving joint function often falls short due to the disease’s progressive and multifactorial nature.
Lack of Regenerative Capability in Conventional Therapies
Core decompression, bisphosphonates, and vascularized bone grafts aim to reduce intraosseous pressure or delay joint collapse but do not regenerate necrotic bone.
Surgical interventions, including total joint arthroplasty, offer symptom relief but are not ideal for younger patients due to prosthesis longevity concerns.
Late Diagnosis and Poor Biomarker Availability
ON often remains asymptomatic until substantial bone collapse occurs, and current imaging modalities (MRI, CT) detect the disease only after considerable damage.
There is a lack of early diagnostic biomarkers to identify at-risk individuals before irreversible necrosis sets in.
Complications of Pharmacologic Approaches
Bisphosphonates and statins have shown some benefit but lack conclusive evidence for disease modification.
Corticosteroid-associated ON continues to rise, especially in immunosuppressed populations, highlighting a treatment-induced risk paradox.
High Recurrence and Multifocal Involvement
Multifocal ON complicates treatment plans and frequently requires multiple surgical interventions.
Even after surgery, the risk of progression or recurrence in untreated joints remains substantial.
These limitations reinforce the urgency for disease-modifying, regenerative strategies like Cellular Therapy and Stem Cells for Osteonecrosis, which aim not only to halt progression but to biologically reconstruct and revitalize necrotic bone tissue [4-7].

8. Cellular Players in Osteonecrosis (Avascular Necrosis): Understanding Bone Pathogenesis
Osteonecrosis (ON), or avascular necrosis (AVN), is characterized by the death of bone tissue due to disrupted blood supply, leading to joint collapse and severe pain. Understanding the cellular mechanisms involved is crucial for developing effective regenerative therapies.
Osteoblasts and Osteocytes:
Osteoblasts are responsible for bone formation, while osteocytes maintain bone tissue. In ON, the death of these cells due to ischemia impairs bone regeneration and structural integrity.
Endothelial Cells:
These cells line blood vessels and are essential for angiogenesis. Their dysfunction in ON leads to inadequate blood supply, exacerbating bone tissue death.
Mesenchymal Stem Cells (MSCs):
MSCs have the potential to differentiate into osteoblasts and endothelial cells, promoting bone regeneration and revascularization. Their therapeutic application aims to restore the cellular balance disrupted in ON.
By targeting these cellular dysfunctions, Cellular Therapy and Stem Cellsfor Osteonecrosis (Avascular Necrosis) aim to restore bone health and prevent disease progression [8-26].
9. Progenitor Stem Cells’ Roles in Osteonecrosis Pathogenesis
Progenitor stem cells (PSCs) are integral to bone repair and regeneration. Their roles in ON include:
Osteogenic PSCs: Differentiate into osteoblasts, aiding in new bone formation.
Angiogenic PSCs: Promote the formation of new blood vessels, restoring blood supply to necrotic areas.
Chondrogenic PSCs: Contribute to cartilage repair, essential in joint preservation.
Harnessing these PSCs can potentially reverse the damage caused by ON [8-26].
10. Revolutionizing Osteonecrosis Treatment: Unleashing the Power of Progenitor Stem Cells
Advanced treatment protocols utilize PSCs to target ON’s core pathologies:
Bone Regeneration: Osteogenic PSCs facilitate the formation of new bone tissue.(CIRM)

By addressing the ischemic and necrotic core pathology of AVN, our approach facilitates functional recovery and joint preservation—transforming how this disabling condition is managed [27-30].
16. Timing Matters: Early Cellular Therapy and Stem Cells for Osteonecrosis for Optimal Musculoskeletal Preservation
Osteonecrosis is a time-sensitive orthopedic emergency. Delayed intervention often results in femoral head collapse and the need for total joint replacement. Our regenerative medicine team emphasizes:
Early-stage Cellular Therapy: Initiating stem cell therapy during Ficat-Arlet Stages I or II significantly improves outcomes by revascularizing necrotic bone and reactivating endogenous osteogenic pathways.
Preventing Subchondral Fracture: Timely therapy strengthens trabecular bone and reduces mechanical stress on the subchondral plate, preserving joint congruity and function.
Restoring Vascular Integrity: EPCs and MSCs work synergistically to restore perfusion and mitigate ischemia-induced apoptosis of osteocytes.
Patients receiving prompt cellular intervention demonstrate superior pain relief, mobility retention, and delay in prosthetic surgery—making early enrollment in our stem cell program essential [27-30].
17. Cellular Therapy and Stem Cells for Osteonecrosis: Mechanistic and Specific Regenerative Properties
Osteonecrosis is driven by impaired blood supply, leading to bone cell death, subchondral collapse, and secondary osteoarthritis. Our multi-lineage cellular therapy strategy targets every pathological layer:
Osteogenic and Chondrogenic Differentiation: MSCs derived from bone marrow, adipose, or Wharton’s jelly differentiate into osteoblasts and chondrocytes, promoting bone matrix regeneration and cartilage resurfacing.
Angiogenesis and Revascularization: EPCs and MSCs upregulate VEGF, FGF-2, and angiopoietins to stimulate new blood vessel formation within ischemic bone, reversing the core insult of avascular necrosis.
Immunomodulation and Anti-apoptotic Action: MSCs secrete IL-10, TGF-β, and HGF to reduce inflammation, suppress osteoclast activity, and inhibit apoptosis of osteocytes in the transition zone of necrosis.
Matrix Remodeling and Collagen Restoration: Stem cells release matrix metalloproteinases (MMPs) to remodel necrotic extracellular matrix and promote deposition of type I collagen for mechanical integrity.
Mitochondrial Transfer: Through tunneling nanotubes, MSCs donate viable mitochondria to dysfunctional osteocytes, enhancing bioenergetics and cellular viability under hypoxic stress.
Our cellular program addresses not just symptom relief, but root causes of ON/AVN—offering a paradigm shift in musculoskeletal regenerative therapy [27-30].
18. Understanding Osteonecrosis: The Five Stages of Structural Bone and Cartilage Failure
Osteonecrosis progresses through a predictable yet devastating series of stages. Targeted regenerative intervention at each phase can halt or even reverse progression.
Stage 1: Preclinical Ischemia (Early ON) Subtle marrow edema with normal radiographs; microcirculatory compromise begins. Cellular Therapy: EPCs and MSCs restore perfusion and prevent osteocyte death, offering the potential for complete reversal.
Stage 2: Necrotic Core Formation MRI reveals sclerosis and bone marrow changes; no collapse yet. Cellular Therapy: Osteogenic MSCs regenerate necrotic trabeculae, while angiogenic factors restore circulation and metabolic exchange.
Stage 3: Subchondral Collapse Structural failure begins; crescent sign visible on imaging. Cellular Therapy: Advanced scaffold-supported stem cell therapy attempts to reconstruct the load-bearing zone and maintain congruity.
Stage 4: Joint Space Narrowing and Cartilage Degeneration Degenerative changes appear; pain and disability increase. Cellular Therapy: iPSC-derived chondrocytes offer cartilage regeneration, delaying arthroplasty.
Stage 5: End-Stage Osteoarthritis and Joint Destruction Complete articular collapse and osteoarthritic changes. Cellular Therapy: Currently experimental but may support joint resurfacing strategies and serve as adjuncts to prosthetics [27-30].

22. Exploring the Sources of Our Allogeneic Cellular Therapy and Stem Cells for Osteonecrosis (Avascular Necrosis)
Our advanced regenerative approach for Osteonecrosis (Avascular Necrosis, AVN) integrates multiple high-potency allogeneic stem cell sources designed to repair ischemic bone tissue, restore vascularization, and regenerate necrotic regions of bone. These include:
Umbilical Cord-Derived MSCs (UC-MSCs): These rapidly proliferating mesenchymal stromal cells are uniquely capable of homing to necrotic bone sites, suppressing inflammatory cytokines (e.g., TNF-α, IL-1β), and stimulating new bone formation through osteogenic differentiation and angiogenic signaling.
Wharton’s Jelly-Derived MSCs (WJ-MSCs): Known for their potent anti-apoptotic and immunomodulatory effects, WJ-MSCs promote bone regeneration by enhancing osteoblast survival, supporting endothelial cell migration, and inhibiting osteoclast-mediated resorption in AVN lesions.
Placental-Derived Stem Cells (PLSCs): PLSCs secrete pro-angiogenic growth factors like VEGF, PDGF, and IGF-1, which are critical for revascularizing ischemic bone and supporting the formation of osteoprogenitor niches within necrotic areas.
Amniotic Fluid Stem Cells (AFSCs): AFSCs contribute to the regeneration of subchondral bone and cartilage interfaces by providing chondroprotective factors and maintaining a supportive extracellular matrix architecture.
Skeletal Progenitor Cells (SPCs): These bone-specific progenitors differentiate directly into osteoblasts and endothelial precursors, facilitating targeted repair of femoral head necrosis and preventing structural collapse.
By leveraging this synergistic cellular portfolio, our Osteonecrosis therapy targets the root causes of bone ischemia, reversing necrosis progression and restoring structural bone integrity [31-33].

We may not accept patients with:
Advanced AVN (Stage IV) with complete femoral head collapse and joint degeneration.
Uncontrolled systemic infections or immunosuppression (e.g., HIV/AIDS).
Active malignancies involving the skeletal system or marrow.
Patients with ongoing high-dose steroid therapy, poorly controlled diabetes, or smoking-related vascular damage must achieve stabilization and undergo lifestyle modification prior to eligibility.
Our safety-first approach ensures that only those likely to benefit from our regenerative strategy are selected, optimizing clinical outcomes while minimizing risk [31-33].
26. Special Considerations for Advanced Osteonecrosis Patients Seeking Cellular Therapy
Although advanced AVN patients may not be ideal candidates, select cases with Stage III lesions who retain partial joint integrity may still benefit under careful clinical supervision. These individuals must submit:
High-Resolution MRI or CT Imaging: To evaluate necrotic volume, joint congruity, and subchondral fractures.
Inflammatory and Vascular Profiles: Including hs-CRP, ESR, VEGF, and D-dimer.
Autoimmune Workup: Screening for lupus, sickle cell disease, and other AVN-associated conditions.
