Dr. Christopher Rogers and Dr. Mary Ambach Publish the First US FDA-Approved Human Clinical Trial on GMP-Manufactured Stem Cell Therapy

Dr. Christopher Rogers and Dr. Mary Ambach Publish the First US FDA-Approved Human Clinical Trial on GMP-Manufactured Stem Cell Therapy

We are pleased to announce that San Diego Orthobiologics Medical Group physicians, Dr. Christopher Rogers and Dr. Mary Ambach were first in the US to publish on the safety and efficacy of a GMP-manufactured stem cell product for patients with osteoarthritis. 1 This FDA / IRB approved study was sponsored by Personalized Stem Cells (PSC), a leader in stem cell research for orthopedic conditions. 2 

Patients with moderate to severe knee osteoarthritis who had not responded to standard medical care were treated with PSC-01, an autologous, adipose-derived cell product, also known as stromal vascular fraction.  

Stromal vascular fraction (SVF) is obtained from a patient’s own adipose tissue (fat) using a simple in-office procedure. Prior clinical trials outside the United States have shown that SVF therapy is safe and effective for knee osteoarthritis. In several clinical trials, adipose-derived cells have demonstrated a superior ability to reduce pain, improve function and promote cartilage regeneration than bone-marrow derived cells. 3, 4, 5

In this clinical trial, the treatment was shown to be safe, well-tolerated and effective. Most of the subjects had been advised to consider joint replacement surgery, however at one year follow-up, 79% were satisfied and able to avoid surgery altogether.  In addition, a single treatment was shown to decrease pain, increase function and improve quality of life for up to 2.5 years.

Treatments that use a patient’s own cells represent an exciting advancement in the field of orthopedic regenerative medicine.  SDOMG and PSC are committed to the responsible development of medical products that use a patient’s own cells to safely decrease pain and improve function.  While SVF products require FDA approval, this treatment offers real hope to all patients who suffer with joint pain.

Is Your Doctor Selling An Illegal Drug?

Is Your Doctor Selling An Illegal Drug?

We want to make you aware of a public health risk that has emerged in San Diego – the illegal sale of fetal tissues for orthopedic conditions. As a result, the FDA and Federal Trade Commission have issued these warnings:

  1. FTC Hold Companies Accountable for Deceptive Claims Regarding Stem Cell Therapy
  2. United States of America Department of Health and Human Services: FDA’s Regulatory Oversight of Regenerative Medicine Products

What is Wharton’s Jelly?

Wharton’s jelly is a tissue within the umbilical cord – the tube connecting a developing fetus with its mother’s placenta. It contains blood and cells that are claimed to useful for orthopedic conditions. But, because it comes from a donor’s body there are multiple safety concerns. Several medical clinics in San Diego now sell Wharton’s jelly injections to their patients, making unsubstantiated claims about its safety and efficacy. We would like to share several issues with this illegal practice with you.

Is Wharton’s Jelly Safe?

The safety of Wharton’s jelly in patients is unknown as no research studies on its use have been conducted in humans.

Is It Effective for Arthritis?

Again, this is unknown. There are no research studies on the efficacy of Wharton’s jelly for any orthopedic condition. Claims made to the contrary are simply unsubstantiated.

Is Wharton’s Jelly FDA-Approved?

The US Food and Drug Administration has issued guidance to physicians regarding the use of Wharton’s jelly. They maintain that Wharton’s jelly is a drug and requires FDA approval. But Wharton’s jelly is not FDA-approved because there are no studies on it’s safety or efficacy and physicians are not permitted to inject it into their patients.

Is my Doctor Permitted to Sell a Drug that is Not FDA-Approved?

Selling a drug that is not FDA-approved constitutes the sale of an illegal drug and may put patients at risk. The FDA has filed injunctions against medical practices that sell illegal drugs and the Federal Trade Commission has fined doctors who make unsubstantiated claims of safety or efficacy.

Is there Any Scientific Evidence for the Use of a Patient’s Own Cells in the Treatment or Orthopedic Conditions?

There are several FDA-compliant, cell-based therapies available to patients with orthopedic conditions. These treatments use a patient’s own cells and include: platelet-rich plasma (PRP), micro-fragmented adipose tissue (MFAT), and bone marrow aspirate (BMAC). These non-surgical treatments have substantial scientific evidence to support their safety and efficacy for several types of orthopedic conditions.


The physicians at SDOMG are board certified, fellowship-trained and nationally recognized experts in using a patient’s own cells to treat orthopedic conditions. We only offer FDA-compliant therapies with substantial scientific evidence for safety and efficacy. If you have any questions about our innovative therapies, please call us for a consultation today.

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.
