Common Questions
Straight answers about regenerative medicine, cost, safety, and what to expect at your visit. Read the regenerative medicine FAQs.
What Is Stem Cell Therapy?
Stem cell therapy is part of regenerative medicine, a field focused on supporting your body’s natural repair process. Your body already uses cells, growth factors, and signaling proteins called cytokines to heal everyday wear and small injuries. Regenerative procedures aim to concentrate these repair tools and place them where you need them, such as a sore knee or a stiff shoulder.
Researchers study several cell sources, including mesenchymal stem cells (MSCs), bone marrow, and adipose (fat) tissue, for their role in tissue repair and inflammation. In the United States, this work is still considered investigational. The science is active and promising, but it is not proven or FDA-approved for joint and orthopedic use. We think you deserve that context up front, not after you book.
Our Regenerative Treatments in California
These are the main regenerative options our California providers discuss with patients. Your consultation decides which, if any, fits your situation. All of them are autologous, meaning they use material from your own body, and all are outpatient and minimally invasive.
Platelet Rich Plasma (PRP)
Platelet rich plasma therapy uses concentrated platelets and growth factors from a small sample of your own blood, placed into a target area, often with ultrasound guidance.
Bone Marrow Derived Procedures
Bone marrow derived stem cell injections use cells collected from your own bone marrow through a step called bone marrow aspiration, then concentrated and placed into the treatment site.
Fat (Adipose) Derived Procedures
Fat derived stem cell injections use cells obtained from your own adipose tissue through a minimally invasive harvest.
How Does the Procedure Work?
Most regenerative procedures follow the same simple path. First, your provider collects the source material, like a small blood draw for PRP or a bone marrow aspiration. Next, that material is prepared to concentrate the useful cells and growth factors. Finally, it is placed into the treatment area, often as an ultrasound-guided or intra-articular injection for accuracy.
The visit usually takes about an hour. Many people go home the same day and ease back into light activity on their provider’s schedule. You will know each step before it happens, and you can preview what to expect from PRP therapy in California.
Areas We Help You Address
People across California come to us with everyday aches that limit how they move and live. During your visit, a provider can talk with you about discomfort and stiffness in the:
- Knee, hip, and shoulder
- Lower back and neck
- Hand, wrist, elbow, foot, and ankle
We focus on how you feel and how you move, including tendon and ligament concerns and general joint stiffness, with the goal of better daily function so you can stay active. If joint pain is your main concern, look at your stem cell therapy options for joints.
Is Stem Cell Therapy Safe?
Like any medical procedure, regenerative treatments carry some risk, and you deserve the full picture first.
The honest regulatory part: the FDA has approved stem cell products only for certain blood and immune disorders, such as some cancers. For joint and orthopedic use, stem cell therapy is investigational and not FDA-approved. PRP from your own blood is handled a little differently, but it is still not a guaranteed fix.
Serious problems are uncommon, but real risks exist, including infection or bleeding at the injection site, swelling, and an immune or allergic reaction. Before any procedure, you go through informed consent, where your provider explains the benefits, the risks, and your other options in plain language.
What Does Stem Cell Therapy Cost in California?
Cost depends on the procedure, the area treated, and your plan, so you get a clear price at your consultation rather than a vague range online. Most regenerative therapies, including PRP and stem cell procedures, are considered experimental and are usually not covered by insurance, which means treatment is generally an out-of-pocket cost. To make care easier to manage, R3 offers financing options for North American patients, and your first consultation is always free.
Why Choose R3 Stem Cell
R3 Stem Cell is led by founder and CEO David Greene, MD, PhD, MBA. Our global network has performed more than 28,000 regenerative procedures across 8 countries over the past decade. R3 also pursued Institutional Review Board (IRB) approval to study regenerative therapies, with that work listed publicly on ClinicalTrials.gov.
We pair that experience with something a lot of clinics skip: honest information, clear informed consent, and zero pressure. You should be able to make a confident decision with real facts in hand.

Frequently Asked Questions
Yes. Licensed providers in California offer regenerative procedures such as PRP and certain same-day, in-office treatments. Some stem cell therapies are considered investigational and are not FDA-approved, so it helps to ask exactly what a provider is offering. This is general information, not legal advice.
For joint, back, and orthopedic concerns, no. The FDA has approved stem cell products only for certain blood and immune conditions. For these other uses, stem cell therapy is still experimental, and any clinic claiming FDA approval for joint pain is not being accurate with you.
Usually not. Because these therapies are viewed as experimental, most plans do not cover them, and treatment is typically out-of-pocket. R3 offers financing to help, and you can review the details at your free consultation.
It depends on you. The number varies from person to person, based on your goals and how your body responds. Your provider gives you a realistic plan at your consultation, not a one-size-fits-all answer.
Results differ for everyone, and no provider can promise a specific outcome or timeframe. Your provider will talk through what may be realistic for your situation.
