If you’ve been researching regenerative medicine, you’ve probably wondered how stem cells actually work. Unlike medications designed primarily to manage symptoms, regenerative orthopedic therapies are being studied for their potential to support the body’s natural healing response through complex cellular communication.
At Dr. Stem Cell, Dr. Bruce Fishman helps patients throughout California understand regenerative medicine and whether it may be appropriate for chronic joint pain, arthritis, tendon injuries, and sports-related conditions.
What Are Stem Cells?
Stem cells are unique because they can self-renew and, under certain biological conditions, develop into specialized cell types. Scientists continue studying how these cells communicate with damaged tissue and influence the body’s natural repair processes.

How Do Stem Cells Work?
Modern research suggests stem cells work largely through cellular signaling. They release signaling molecules, growth factors, cytokines, and extracellular vesicles that communicate with surrounding tissues. These signals may help coordinate the body’s natural healing response.
- Support healthy inflammatory responses
- Promote communication between cells
- Support tissue remodeling
- Encourage blood vessel development
- Assist normal repair processes
Why Cellular Signaling Matters
Every injury triggers a biological cascade. Stem cells may influence how nearby cells respond to injury by releasing biochemical messengers rather than acting as simple replacement cells.
Stem Cells and Orthopedic Conditions
Patients frequently research regenerative orthopedic therapies for knee arthritis, tendon injuries, shoulder pain, spinal stenosis, hip injuries, and chronic joint pain.

PRP vs. Stem Cell Therapy
PRP and stem cell therapy are both regenerative approaches but function differently. Learn more in PRP vs. Stem Cell Therapy.
Stem Cell Therapy vs. Cortisone Injections
Many patients compare regenerative medicine with steroid injections before making a decision. Read Stem Cell Therapy vs. Cortisone Injections.

Frequently Asked Questions About How Stem Cells Work
How do stem cells actually work?
Stem cells work primarily through a process known as cellular signaling. Rather than simply replacing damaged tissue, stem cells release signaling molecules, growth factors, cytokines, and extracellular vesicles that communicate with surrounding cells. These biological signals may help coordinate the body’s natural healing response, regulate inflammation, and support tissue repair.
Do stem cells replace damaged tissue?
Current research suggests that stem cells do more than simply replace damaged cells. Their greatest contribution may be their ability to influence nearby tissues through cellular communication, helping support the body’s natural repair processes. Scientists continue studying exactly how these mechanisms work in different orthopedic conditions.
What conditions are stem cells commonly used to evaluate?
Regenerative orthopedic therapies are commonly explored for conditions such as osteoarthritis, chronic knee pain, meniscus tears, rotator cuff injuries, tendon injuries, spinal stenosis, hip labral tears, tennis elbow, and other musculoskeletal conditions. Every patient should undergo a comprehensive evaluation to determine whether regenerative medicine may be appropriate for their individual condition.
Are stem cells the same as PRP?
No. Platelet-Rich Plasma (PRP) and stem cell therapy are both regenerative treatments, but they work differently. PRP uses concentrated platelets from the patient’s own blood to deliver growth factors that support healing, while stem cell-based therapies involve biologic cells that communicate with surrounding tissues through cellular signaling.
How long does stem cell therapy take to work?
Every patient responds differently. Factors including the condition being treated, severity of the injury, overall health, rehabilitation, and lifestyle can all influence recovery. Because regenerative medicine supports the body’s natural healing response, improvements may occur gradually over time.
Is stem cell therapy FDA approved?
Regenerative medicine is an evolving field. Patients should discuss available treatment options, current regulations, and whether a particular therapy may be appropriate for their specific condition with a qualified physician. Dr. Bruce Fishman provides individualized evaluations based on each patient’s needs, diagnosis, and treatment goals.
Can stem cells help arthritis?
Researchers continue studying the role of regenerative medicine in supporting patients with osteoarthritis and other degenerative joint conditions. While stem cell therapy is not considered a cure for arthritis, many patients explore regenerative orthopedic options as part of a comprehensive treatment plan designed to support mobility, joint function, and quality of life.
Why is regenerative medicine becoming more popular?
Many patients are looking for minimally invasive treatment options that may help support healing without surgery. Advances in regenerative medicine research have increased interest in biologic therapies for chronic orthopedic conditions, sports injuries, tendon injuries, and degenerative joint disease. As research continues to evolve, more patients are seeking educational resources to better understand how regenerative orthopedic treatments may fit into their overall care plan.
