Platelet Rich Plasma and Stem Cell Therapies

Platelet Rich Plasma and Stem Cell Therapies

What’s the Difference Between Platelet Rich Plasma and Cell Based Therapies?

Regenerative medicine therapies are increasingly being used for people with painful orthopedic conditions.  Commonly used orthobiologics include platelet rich plasma (PRP) and other cell based therapies.

Platelet rich plasma therapy includes the concentration of platelet cells from a patient’s own blood.  These cells deliver hundreds of growth factors which facilitate the body’s ability to control inflammation, decrease pain and promote tissue healing.

Adult Stem Cells are found in every tissue in the body.  A patient’s own bone marrow and fat tissues contains precursor cells called mesenchymal stem cells that have the ability to develop into new cells and repair damaged tissues.  These cells also reduce pain and inflammation.

So What’s the Difference?

Many patients ask, “If both platelet rich plasma and adult stem cell therapy help with healing and inflammation, why choose one over the other?”

The fact of the matter is each treatment offers unique benefits.  An experienced regenerative medicine specialist knows that several key factors are important when determining which treatment will provide the best outcome for you.

These considerations include:

·       The severity of the medical condition being treated (e.g. mild, moderate or severe)

·       The location of the injury (e.g. spine or joint)

·       The type of tissue requiring treatment (e.g. bone, tendon, cartilage, disc or muscle)

·       The patient’s age and overall health, including any other medical conditions.

Knowing How PRP is Different Than Cell Based Therapies

Many clinics claim to offer stem cells or platelet rich plasma treatments, however, the effectiveness of these treatments and experience level of the physicians varies widely from one clinic to another.

·        Treatments that use donated tissues such as umbilical cord blood, amniotic tissue and exosomes are not permitted under current FDA guidelines.  These products are NOT to be  used in orthopedic conditions, because they have not been tested for safety or efficacy.

Only autologous biologics such as your own blood, bone marrow and minimally manipulated fat are compliant with current FDA guidelines for safety and efficacy.

·       Dose matters.  The number of cells obtained is determined by the method used.  The best results are achieved when your physician uses advanced tissue processing methods to produce highly concentrated platelet rich plasma or mesenchymal stem cells.  It takes your physician years to master the skill of cell harvesting for maximal benefit.

·       To ensure the safe, effective and comfortable delivery of cells into the damaged tissues, a fellowship trained physician should use advanced image guidance using diagnostic ultrasound or x-ray (fluoroscopy).  Physician assistants, naturopathic doctors, chiropractors and nurses do not complete this level of training.

When considering treatment with regenerative medicine, it’s important to understand the pros and cons of the different options.  Be aware that treatments vary among different clinics and outcomes are determined by physician experience and the methods used to deliver these treatments.  Be sure to ask your physician about their training, experience and whether or not they document their patient outcomes.

When done properly, cell based therapies significantly help patients to heal quickly and completely allowing them to enjoy an active life without pain.

Drs. Christopher J. Rogers and Mary A. Ambach of San Diego Orthobiologics Medical Group have successfully treated thousands of patients with platelet rich plasma and other cell based therapies for more than a decade. Their facility in Carlsbad contains the most advanced Regenerative Medicine technology in San Diego and offers same day treatments with the highest documented levels of safety and efficacy.


What Are the Risks & Benefits of Cell-Based Treatments?

What Are the Risks & Benefits of Cell-Based Treatments?

Many people are discovering the benefits of cell based therapies, commonly known as stem cell treatments, in treating orthopedic conditions such as osteoarthritis, tendon injuries and chronic low back pain. These treatments have offered patients hope for long term pain relief and healing. Patients have obtained significant medical benefits from physicians who offer safe and evidence based cell therapy.

Although there is increasingly abundant data on the benefits of these treatments, many stem cell therapies are in the investigational stages of development. The U.S. Food and Drug Administration (FDA) regulates the use of stem cells in clinical practice. Healthcare providers that offer cell based therapies are obligated to comply with state and federal regulations. 

Unfortunately, in the U.S. there are more than 600 clinics that promote stem cell treatments that are neither safe nor effective. The level of healthcare provider training at these clinics is highly variable with many delivering treatments from unqualified individuals.  So when patients ask, “Does stem cell treatment work?”, the answer is, “It depends on the clinic what they are offering as stem cell treatment.”.  We believe it is important for physicians and their patients to understand the key differences between cell based treatments and the providers who offer them.

Several “stem cell” clinics use birth tissue derived from umbilical cord blood or amniotic tissue.  Others will offer exosomes which are products derived from stem cells.  These products are not FDA compliant for orthopedic use.  They require FDA approval of a Biologics License Application before physicians are permitted to market them to patients.  In an effort to evade FDA scrutiny, the manufacturers of these products claim that their birth tissue products do not contain live stem cells.  Yet the clinics that sell these products make very different claims.

What sets San Diego Orthobiologics Medical Group apart from other clinics is our commitment to only use FDA compliant cell based therapies that are supported by the scientific evidence.  In addition, we use cells that are obtained from the patient’s own body (autologous cells) to maximize safety.

Two Sources of Cell-Based Treatments

Stem cells are found throughout the body.  Common sources used to obtain stem cells are bone marrow aspirate concentrate (BMAC) and adipose tissue (fat) that has been processed in an FDA compliant manner.  These tissues are known to contain live stem cells, however it is difficult to accurately measure the number of cells at the time of treatment.  In addition to stem cells, there are many other kinds of cells in bone marrow and fat that contain healing properties.  Cell based treatments that are obtained from these tissue sources comply with current FDA guidelines and are supported by several scientific studies that report on the safety and efficacy of these therapies for orthopedic conditions.

  • Adipose-derived cells are collected from a mini-liposuction procedure, typically from the abdomen or buttocks.  San Diego Orthobiologics Medical Group offers  LIPOGEMS® autologous fat tissue product for treating joint and soft tissue injuries. LIPOGEMS® preserves cells within the fat without jeopardizing their native structure. This enables reparative cells within the fat to continue to work as a functional unit allowing the body to repair damaged or degenerated tissues.
  • Bone marrow derived cells contain a rich supply of cells that have been shown to stimulate the body’s ability to improve circulation, decrease inflammation and heal injured tissues. San Diego Orthobiologics Medical Group offers bone marrow aspirate concentrate, which provides a significant amount of regenerative cells to support the body’s natural healing response.

Patient Safety is Paramount

Because San Diego Orthobiologics Medical Group uses a patient’s own tissue, there is minimal risk of disease transmission, infection or immune reaction.  This would not be the case for donor birth tissue derived products.  Moreover, autologous cells used in our treatments are preserved in their natural state and possess the greatest healing potential. Donor or birth tissue products have not been proven to be safe or effective for orthopedic conditions. There have been cases of bacterial infection with the use of donor products and most do not contain any living stem cells at all.

In addition to using a patient’s own cells, San Diego Orthobiologics Medical Group also protects our patients using:

  • State of the art cell processing techniques in our Orthobiologics lab using some of the most advanced regenerative medicine technology in San Diego.
  • Innovative equipment to image the joint and spine such as musculoskeletal ultrasound and fluoroscopy (digital x-ray). These tools provide detailed visualization of the injured structures and significantly improve the comfort and effectiveness of cell based therapies.
  • Fellowship trained physicians who have decades of experience treating patients with orthopedic conditions.  We also track our safety and efficacy outcomes with the DataBiologics registry to help patients make informed medical decisions.

An Investment in Safety

San Diego Orthobiologics Medical Group invests significant time and expertise to ensure we offer FDA compliant and evidence based therapies in order to provide our patients with safe, comfortable and effective treatments. As dedicated healthcare professionals, we understand that every patient is unique and that the best outcomes are derived after a comprehensive evaluation, patient education of all treatment options and customized medical care.

Drs. Christopher J. Rogers and Mary A. Ambach of San Diego Orthobiologics Medical Group are experts in the field of regenerative medicine and have been providing safe, effective and FDA-compliant cell based treatments to their patients for decades. They serve as faculty members and lecturers at national and international medical conferences and are considered experts in the field of regenerative medicine.




Researchers and FDA Post Warning Against Fraudulent Illegal Tissue Products

Researchers and FDA Post Warning Against Fraudulent Illegal Tissue Products


Stem cell therapies have the potential to treat many medical conditions that were previously untreatable.  But, despite their enormous promise, stem cell therapies are only in the early stages of clinical development.  For the past two decades, hundreds of scientific studies have been conducted, but much more work is required to prove the safety and efficacy of these treatments.

Recently, the FDA posted a warning to patients about the rising number of illegal stem cell clinics.  In addition, a newly released short film documents the fraudulent and illegal activity of these stem cell clinics.  Experts in the field were interviewed and shared their experience, warning patients about the fraud and abuse that is rampant in the United States.

Unscrupulous healthcare providers sell illegal birth tissue products and fraudulently promote them as “stem cell therapy”.  These products include amniotic fluid, umbilical cord blood and exosomes.  They are not FDA approved because they have not been tested for safety or efficacy.  Physicians are not permitted to use them.  In fact, patients have been harmed by them.  And not surprisingly, none of these products have been shown to contain actual live stem cells.

Patient Education is Key

The physicians at San Diego Orthobiologics Medical Group support the experts and would like to educate patients about the risks of using illegal stem cell products.  We only use FDA compliant cell therapies for our patients.  We do not use birth tissue products because they have not been tested for safety or efficacy and are not permitted by the FDA.  Our physicians are recognized leaders in the field of Orthobiologics, conduct FDA approved stem cell research and have published in the peer-reviewed scientific literature.

Bone Marrow Stem Cell Injections

Bone Marrow Stem Cell Injections

It has been more than fifty years since the first bone marrow transplant was performed to treat an infant with immune deficiency (1). In the years following that milestone, researchers and physicians have discovered new ways to use the bone marrow and its powerful stem cells to treat a number of different medical illnesses, including orthopedic conditions. Dr. Arnold Caplan discovered the mesenchymal stem cell in the early 1990’s (2). These cells are a specific type of adult stem cell found in the bone marrow that have the ability to renew themselves and differentiate into bone, tendon, cartilage and muscle cells.
Patients who suffer with joint arthritis, tendinopathy or ligament sprains benefit from bone marrow cell therapy, which stimulates the body’s natural ability to improve circulation, decrease inflammation and heal injured tissues.

What is Bone Marrow Aspirate Concentrate (BMAC)?

Although the name sounds complicated, bone marrow aspirate concentrate (BMAC) simply describes the source, method and process for removing cells from a patient’s own body, preparing them and reintroducing them into an injured area.

Bone marrow is a source of therapeutic cells. It contains powerful mesenchymal stem cells that can be collected for treatment. It also contains other Orthobiologics such as platelets, growth factors and proteins that contribute to the therapeutic effects. Aspirate refers to the way the therapeutic cells are collected into a syringe. About four tablespoons of bone marrow is removed (aspirated) from the back of the hip area. Concentrate is the term that describes how the bone marrow is processed. The aspirated bone marrow is transferred into a centrifuge that spins the sample, separating it into different layers and concentrating the therapeutic cells.

Is BMAC Effective?

BMAC has the ability to address the symptoms and root cause of spine and joint pain by decreasing inflammation and promoting the healing of the injured tissues. Current research and clinical experience have shown promising results in decreasing pain and stiffness, improving function and enhancing cartilage and bone healing in patients with osteoarthritis, tendon injuries and other orthopedic conditions. The benefits of these treatments typically last 2 to 5 years or longer.

This is a minimally invasive, non-surgical procedure that does not require hospitalization or lengthy rehabilitation. In fact, patients are back home within a few hours of the procedure and resume normal activities within a week. Most patients require only a single treatment, but it can easily be repeated if necessary.

How Your Body Heals After Cell-Based Therapy

How Your Body Heals After Cell-Based Therapy

The human body is programmed to heal. Whether it is recovering from a small scrape or from major surgery the body’s initial response to any kind of injury or trauma is to kick into healing mode.

But sometimes it can use a little help. And that is what cell-based therapies offer.

How Cell-Based Therapy Works

Cell-based therapy assists the body to heal injured tissues. This is especially useful for the treatment of injured tendons, ligaments and joints. Cell-based therapy delivers targeted healing factors that are taken from the patient’s own cells to boost the body’s ability to speed healing and recovery.

There are several treatments options available, and each one offers unique benefits that enable your physician to choose the best option for you.

  1. Platelet Rich Plasma therapy concentrates platelet cells from the blood and delivers them to the injured tissues. These cells are rich in growth factors that are needed to initiate the body’s healing and repair processes. Using a patient’s own blood, the platelets are separated and concentrated. They are then placed into the injured area to boost healing. 
  2. Prolotherapy delivers a targeted solution of concentrated dextrose and local anesthetic to injured ligaments, tendons or joints. The body responds to the dextrose solution as an irritant which, triggers healing responses that had stalled prematurely.
  3. Stem Cells are found throughout the body and are activated when an injury occurs.  Tissue harvested from the patient’s own bone marrow or adipose (fat) contain mesenchymal stem cells (MSCs). They activate healing by producing molecules that direct other cells in the area to form new blood vessels, awaken resident progenitors and stimulate new tissue growth.  Cells can be obtained from several sources, however, only bone marrow and adipose (fat) tissue are FDA-compliant for orthopedic indications. Umbilical cord blood products are not approved by the FDA and not supported by clinical research for orthopedic use.

What to Expect While Recovering from Therapy

Unlike major surgery, cell-based therapies do not require hospitalization. They are performed in our office procedure suite with local anesthetic.  Recovery usually takes less than 4 days from these minimally invasive procedures.

There may be some swelling and discomfort in the injected area, but these symptoms typically lessen within a few days.  Patients begin physical therapy to regain strength and range of motion within the first few weeks. Depending on the extent of the original injury, as well as the specific treatment used, some patients are able to resume their normal activity levels just days after their procedures.

Staying well hydrated and following a nutrient-rich diet are key to overall wellness and are especially important before and after these treatments since the body’s requires high-quality fuel to power their healing efforts. 

San Diego Orthobiologics Medical Group is a leader in regenerative medicine therapies and offers a great variety of treatment options depending upon each patient’s unique needs. With decades of experience in the field of minimally invasive interventional treatments, Drs. Christopher J. Rogers and Mary A. Ambach are experts in the field of regenerative medicine. They serve as faculty members and lecturers at national and international medical conferences and serve on the board of directors for several national regenerative medicine organizations.
