What is the process?

  • Physician screens and accepts patient
  • Day #1 – Physician collects fat
  • Day #2 – PSC processes fat and creates doses
  • Day #3 through 18 – Quality testing of cells – quality approval
  • Any time after approval – cells are delivered for injection Extra cells are stored for future use

What are Adipose Derived Cells?

The cells produced from processing of adipose are commonly referred to as Stromal Vascular Fraction (SVF) cells. The SVFs contains multiple cell types, many of which have been shown to be useful in reduction of inflammation, reduction of pain, and acceleration of healing.

What are cultured stem cells and what is the reason to have them?

PSC may culture (grow additional cells) cells for potential use in future FDA approved clinical trials. Cultured cells are grown to produce additional doses in order to avoid the need for additional fat collection procedures.

Can I store extra cells?

Yes. The PSC cell banking service is designed for long-term stem cell storage. An annual Cell Banking Agreement will be provided after the first year of storage.

What conditions can be treated?

PSC supplies stem cells only to physicians treating certain conditions under FDA approved clinical studies. Currently arthritis is being treated. Please see the Clinical Studies page for more information.

What conditions will be treated in the future?

PSC plans to apply for FDA IND’sfor additional medical conditions as indicated by the latest clinical evidence and science. Please see the Clinical Studies page for more information. Please contact us with your specific interest so that we can provide updates as available.

What are Stem Cells and what do they do?

Stem Cells:

  • Are the natural healing cells in the body and is derived from a sample of a patient’s own fat
  • Have been shown to
  • Accelerate healing
  • Reduce pain
  • Reduce inflammation
  • Are able to differentiate into multiple cell types

What is your quality control protocol?

The founders of PSC have more than 20 years of experience conducting clinical studies and operating service laboratories under FDA and USDA guidelines. PSC performs sterility, stability, and purity testing for every process.

Is the tissue source of stem cells important?

Stem cells from fat have 100 to 500 times more stem cells than bone marrow. Also, fat is plentiful and easy to harvest.

How does Bone Marrow compare with Fat-Derived stem cells?

Bone marrow:

  • Consists of mostly blood (only 1 out of 50,000 cells is a mesenchymal stem cell)
  • May contain bone fragments, which is not ideal for injecting into joints, tendons, or ligaments
  • Contains variable amounts of growth factors
  • Collection method requires drilling into the bone for harvest

What is PRP?

Platelet-rich plasma:

  • PRP has very few stem cells
  • Platelets are harvested from blood and activated before injection
  • Platelets contain growth factors.
  • Unlike Stem Cells, platelets cannot respond to cellular signals, specific tissue needs, or the severity of the injury.

Is it safe?

Your physician will review with you the possible risks that are in the Consent Form approved by the Institutional Review Board (IRB) for each clinical trial.

Am I too old for Stem Cell Therapy?

Age may decrease stem cell concentration, but fat almost always contains sufficient cells for doses or culturing of more cells. Your physician includes age as well as other factors while screening for enrollment criteria for each clinical trial.

Can my cells be shipped to any physician?

No. Cells can only be shipped to a physician who is participating in an FDA approved trial sponsored by PSC or to a country that has authorized the use of GMP produced stem cells.

How are the cells shipped?

The cells are packaged in sterile vials and shipped to your physician in a cryogenic shipping system.

How much will it cost?

The cost for participation in each clinical trial will vary depending on the cost for diagnosis, eligibility screening, number and type of treatments, and follow up exams. You should review costs with your physician prior to enrollment in the clinical trial.

Is stem cell therapy covered by insurance?

Stem cell therapy is not typically covered by insurance. The cost of diagnosis and post-treatment visits or therapy may be covered. You should review coverages with your insurance carrier prior to enrollment in the clinical trial.

What medications or treatments can be used with stem cell therapy?

Your physician will review your current medications as part of the eligibility screening process.
