Description:

Mesenchymal stem cells (MSCs) are being investigated as a regenerative biologic agent because of their ability to differentiate into multiple tissue types and to self-renew. MSCs can be derived from a variety of sources, including adipose tissue, bone marrow, placenta and peripheral or umbilical blood, however, the bone marrow is currently the primary source of mesenchymal stem cell procurement. MSC therapy has been proposed as a treatment option for orthopedic indications that include but are not limited to the following:

  • Knee -  arthritis, meniscus tears, tendon and ligament tears, overuse injuries and other conditions
  • Hip – injuries, arthritis, bursitis and other degenerative conditions
  • Shoulder – arthritis, rotator cuff tears, and other shoulder conditions
  • Spine and cervical conditions – back pain, pain from bulging or herniated discs, degenerated disc or pain from an extruded or torn disc
  • Elbow – injuries, overuse conditions and arthritis (tendon and ligament issues)
  • Hand/Wrist – arthritis and other conditions
  • Foot/Ankle – ligament tears, sprains and instability of the ankle joint, an alternative to fusion or replacement surgery of the ankle 
  • Non-union fractures 

MSCs are multipotent cells (also called stromal multipotent cells) that possess the ability to differentiate into various tissues including organs, trabecular bone, tendon, articular cartilage, ligaments, muscle, and fat. MSCs are associated with the blood vessels within bone marrow, synovium, fat, and muscle, where they can be mobilized for endogenous repair as occurs with healing of bone fractures. Bone-marrow aspirate is considered to be the most accessible source and, thus, the most common place to isolate MSCs for treatment of musculoskeletal disease. However, harvesting MSCs from bone marrow requires an additional procedure that may result in donor-site morbidity. In addition, the number of MSCs in bone marrow is low, and the number and differentiation capacity of bone marrow-derived MSCs decreases with age, limiting their efficiency when isolated from older patients.

 

Tissues such as muscle, cartilage, tendon, ligaments, and vertebral discs show limited capacity for endogenous repair. Therefore, tissue engineering techniques are being developed to improve the efficiency of repair or regeneration of damaged musculoskeletal tissues. Tissue engineering focuses on the integration of biomaterials with MSCs and/or bioactive molecules such as growth factors. In vivo, the fate of stem cells is regulated by signals in the local 3-dimensional microenvironment from the extracellular matrix and neighboring cells. It is believed that the success of tissue engineering with MSCs will also require an appropriate 3-dimensional scaffold or matrix, culture conditions for tissue-specific induction, and implantation techniques that provide appropriate biomechanical forces and mechanical stimulation. The ability to induce cell division and differentiation without adverse effects, such as the formation of neoplasms, remains a significant concern. Given that each tissue type requires different culture conditions, induction factors (signaling proteins, cytokines, growth factors), and implantation techniques, each preparation must be individually examined.

 

Regenexx® Stem Cell Procedure

Stem cells act as the repairman of the body and as people age and get injuries there are sometimes not enough of these critical repair cells getting to the injured area. The Regenexx procedures help solve this problem by greatly increasing the body’s natural repair cells and promote healing. This is accomplished by harvesting cells from the areas known to be rich in mesenchymal stem cells and then concentrating those cells in a lab before precisely re-injecting them into the damaged area in need of repair.  

 

The Regenexx Same-Day Stem Cell Protocol is called a same-day procedure because the stem cells are harvested and reinjected in the same day. However, for most patients the complete protocol is actually a series of injections that happen over the course of about a week, depending on the individual’s situation. These injections include a pre-injection, the same day stem cell extraction and reinjection procedure, followed by a post-injection of multiple proprietary platelet mixes a few days later.

 

On the day of the procedure, blood is drawn from the patient’s vein from their arm. This will be processed in the lab along with the stem cell sample. The first step of the procedure is the bone marrow aspiration, the doctor will thoroughly numb the back of the hip and take a small bone marrow sample through a needle. These samples are sent to the lab which is part of the medical practice and processed.

 

The mesenchymal stem cells are isolated from the bone marrow sample, while some practices add platelet rich plasma (PRP) to their stem cell concentration, for this procedure a “super platelet” mix is utilized. By mixing lab prepared PRP (slow release growth factors) and platelet lysate (immediately available growth factors), adult stem cells grow many times more than with just PRP or platelet lysate alone. The goal is to deliver much greater numbers of stem cells to the injured area than the body would deliver on its own. 

 

Once the cells are processed the patient will return and the stem cells and natural growth factors from the blood platelets are re-injected into the injured area using either real time fluoroscopy or musculoskeletal ultrasound, which allows the physician to pinpoint the exact location of the injection into the injured area as well as the dispersion of the cells into the tissues. Re-injections can be as soon as 6 weeks and it is recommended that most patients will need 2-4 injection cycles.

 

Common Conditions Treated:

  • Osteoarthritis of the knee, hip, ankle, shoulder, hands
  • Patients with non-healing bone fractures
  • Certain types of injuries to the meniscus, hip labrum, shoulder labrum, shoulder SLAP lesions
  • Tendon injuries such a partial rotator cuff or other partial muscle-tendon tears
  • Avascular necrosis of the hip, shoulder, knee, ankle

 

Regenexx Network Providers

Regenexx is a national network of musculoskeletal doctors specializing in advanced regenerative medicine protocols, developed and patented by Regenexx. These physicians practice “Interventional Orthopedics” by providing non-surgical biologic therapies delivered with high accuracy through a needle. Regenexx network providers are board certified musculoskeletal medicine specialists that have joined this exclusive network. Joining this network involves extensive training in addition to having the ability to perform in depth, complex musculoskeletal exam lasting more than 25-30 minutes of hands on time with the patient is required or must be learned. This includes the ability to quantify problems of stability, nerves, muscles, joints and body symmetry.

 

Summary 

The evidence for stem cell therapy in individuals who have various orthopedic conditions (osteoarthritis, ligament and tendon injuries, spinal conditions, non-union fractures,  osteonecrosis) includes small randomized controlled trials and nonrandomized comparative trials. Relevant outcomes are symptoms, morbid events, functions outcomes, quality of life, and treatment-related morbidity. Use of mesenchymal stem cells (MSCs) for orthopedic conditions is an active area of research. Despite continued research into methods of harvesting and delivering treatment, there are uncertainties regarding the optimal source of cells and the delivery method. Studies have included MSCs from bone marrow, adipose tissue, peripheral blood, and synovial tissue. The largest body of evidence is on the use of autologous MSCs, either concentrated or expanded in culture, for cartilage repair. This evidence includes small randomized and nonrandomized comparative trials with insufficient data to evaluate health outcomes. In addition, expanded MSCs for orthopedic applications are not U.S. Food and Drug Administration (FDA) approved (concentrated autologous MSCs do not require FDA approval). Overall, there is lack of evidence that clinical outcomes are improved.  Additional comparative prospective randomized clinical trials with a larger number of patients are needed to adequately compare MSC based therapies to standard treatment modalities to permit greater certainty on the effect of this treatment on net health outcomes. The evidence is insufficient to determine the effects of this technology on net health outcomes.

 

Mesenchymal Stem Cells (MSCs) with Demineralized Bone Matrix (DBM)

Demineralized bone matrix (DBM) is a type of allograft. It is produced through a process that involves the decalcification of cortical bone; substantially decreasing the structural strength. However, it is more osteoinductive than ordinary allograft. Although the reason for this is not completely understood, it has been speculated that the osteoinductive growth factors contained in the extracellular bone matrix are easily accessed once the mineral phase of the bone has been removed. 

 

Cell Based: Bone graft substitutes that are cell based use cells to generate new tissue either alone or seeded onto a support matrix (e.g. in combination with allograft material). Support matrix may include xenograft (i.e. bovine) or human type I collagen. Cell based substitutes that are available include mesenchymal and other cell based products.

  • Mesenchymal stem cells (MSCs) may also be administered by combining the cells with demineralized bone matrix (DBM). DBM is considered minimally processed tissue and does not require FDA approval. MSCs are multipotent stem cells that express a variety of different cell surface proteins and can differentiate into a variety of cell types. Obtained from bone marrow they have shown to differentiate into osteoblasts, chondrocytes, myocytes, adipocytes and neuronal cells.  
  • The use of demineralized bone matrix (DBM) with MSCs has been and continues to be investigated for various procedures, including spinal fusion and for intervertebral disc regeneration. Although currently under investigation, data published in the medical literature evaluating cell based substitutes is in preliminary stages and mainly in the form of nonhuman trials or case reports; data supporting safety and efficacy are lacking. Therefore, the use of allograft bone products containing viable stem cells, including but not limited to demineralized bone matrix (DBM) with stem cells, is considered investigational for all orthopedic applications, due to the lack of evidence supporting safety and efficacy. 

 

Practice Guidelines and Position Statements

American Academy of Orthopedic Surgeons (AAOS)

The American Academy of Orthopedic Surgeons (AAOS) states the following: “Stem cell procedures in orthopedics are still at an experimental stage and most musculoskeletal treatments using stem cells are performed in research centers as part of controlled clinical trials.” 

 

Regulatory Status

Concentrated autologous  mesenchymal stem cells (MSCs) do not require approval by the U.S. Food and Drug Administration (FDA).

 

Demineralized bone matrix (DBM), which is processed allograft bone, is considered minimally processed tissue and does not require FDA approval. At least 4 commercially available DBM products are reported to contain viable stem cells:

  • Allostem® (AlloSource): partially demineralized allograft bone seeded with adipose-derived MSCs
  • Map3™ (rti surgical) contains cortical cancellous bone chips, DBM, and multipotent adult progenitor cells
  • Osteocel Plus® (NuVasive): DBM combined with viable MSCs that have been isolated from allogeneic bone marrow
  • Trinity Evolution Matrix™ (Orthofix) DBM combined with viable MSCs that have been isolated from allogeneic bone marrow

Whether these products can be considered minimally manipulated tissue is debated. A product would not meet the criteria for FDA regulation part 1271.10 if it is dependent upon the metabolic activity of living cells for its primary function. Otherwise, a product would be considered a biologic product and would need to demonstrate safety and efficacy for the product’s intended use with an investigational new drug and Biologics License Application (BLA).

 

No products using engineered or expanded MSCs have been approved by FDA for orthopedic applications.

 

In 2008, FDA determined that the mesenchymal stem cells sold by Regenerative Sciences for use in the Regenexx™ procedure would be considered drugs or biological products and thus require submission of a New Drug Application (NDA) or Biologics Licensing Application (BLA) to FDA.  In 2014, a federal appellate court upheld FDA’s power to regulate adult stem cells and drugs and biologics and ruled that Regenexx cell product fell within FDA’s authority to regulate human cells, tissues, and cellular and tissue-based products.  To date, no NDA or BLA has been approved by FDA for this product. As of 2015, the expanded stem-cell procedure is only offered in the Cayman Islands. Regenexx™ network facilities in the U.S. provide same-day stem-cell and blood platelet procedures, which do not require FDA approval (this information can be found on the Regenexx website under frequently asked questions (FAQ).

Stem Cell Therapy for Orthopedic Indications

Mesenchymal stem cell therapy including but not limited to the Regenexx Procedure is considered investigational for all orthopedic applications, including use in repair or regeneration of musculoskeletal tissue.

 

The use of mesenchymal stem cells (MSCs) for orthopedic conditions is an active area of research. Current available evidence on procedures using mesenchymal stem cells (MSCs) for orthopedic indications consists of small randomized and nonrandomized trials with insufficient data to evaluate health outcomes. Additional comparative prospective randomized clinical trials are needed to adequately compare MSC based therapies to standard treatment modalities to permit greater certainty on the effect of this treatment on net health outcomes. Also, there are no society guidelines that recommend the use of MSC therapy for the treatment of orthopedic indications. The American Academy of Orthopedic Surgeons (AAOS) information states, “stem cell procedures in orthopedics are still at an experimental stage and most musculoskeletal treatments using stem cells are performed in research centers as part of controlled clinical trials.” The evidence is insufficient to determine the effects of this technology on net health outcomes.

 

  

Stem Cells with Demineralized Bone Matrix (DBM) for Orthopedic Indications

Allograft bone products containing viable stem cells, including but not limited to demineralized bone matrix (DBM) with stem cells, is considered investigational for all orthopaedic applications, due to a lack of evidence supporting safety and efficacy by review of the available published peer reviewed medical literature. 

  

Note: See regulatory information above for demineralized bone matrix (DMB) products containing viable stem cells.
