Stem Cells: 7 Myths and the Truth

Q: Is stem cell treatment dangerous?

Autologous (own) stem cells are safe—no risk of rejection. Over 25,000 procedures at MIBRAR® with no serious complications recorded. Allogeneic (donor) cells are less studied.

Q: How long until stem cells start working?

First improvements—2–4 weeks (inflammation reduction). Structural tissue regeneration—3–6 months. Maximum effect—6–12 months post-procedure.

«Stem cells»—a term used by everyone: from serious clinics to beauty salons. Patients hear promises to «grow new cartilage» and «rejuvenate joints,» but reality is more complex. We debunk 7 most persistent myths.

Myth 1: «Stem cells can grow a new joint»

Truth: Mesenchymal stem cells (MSCs) can differentiate into chondrocytes and osteoblasts, but growing a whole anatomical structure in vivo is not yet possible. Science can stimulate regeneration of damaged tissue—restoration of cartilage, healing of the disc's fibrous ring, acceleration of fracture healing.

This is not «growing a new joint,» but real reduction of degeneration and restoration of function.

Myth 2: «All stem cells are the same»

Truth: There is a fundamental difference between types:

Embryonic—NOT used in orthopedics (ethical restrictions)
Allogeneic (donor)—risk of rejection, not legal in all countries
Autologous (own)—from bone marrow (BMAC), adipose tissue (SVF/Lipogems®), blood (PRP/CGF)

Autologous MSCs from adipose tissue (Lipogems® technology) are considered the gold standard: minimal invasiveness of harvest, high cell concentration, no rejection risk.

Myth 3: «One injection solves everything»

Truth: Results depend on:

Precision of delivery—cells must reach exactly the damage (that's why MIBRAR® uses 3D navigation Cyber Navi Hand™)
Concentrate quality—standard PRP contains 5–10 times fewer growth factors than CGF
Disease stage—stage II osteoarthritis responds better than stage IV
Rehabilitation—without proper recovery protocol, effect diminishes

Myth 4: «Stem cells are experimental therapy»

Truth: Autologous cell concentrates are approved by regulators:

Lipogems®—FDA 510(k) clearance, CE Mark class IIa
PRP/CGF—standard in European orthopedics, >15,000 PubMed publications

This is not «experimental,» but a class of medical procedures with 20-year history and hundreds of thousands of procedures performed.

Myth 5: "Stem Cells Help with Any Disease"

Truth: Cell therapy is not effective for all conditions. The evidence base is strong for:

? Knee Osteoarthritis (Gonarthrosis) stages I–III
? Hip Osteoarthritis (Coxarthrosis) stages I–III
? Herniated Discs
? Rotator Cuff Tears
? Meniscus Tears
?? Stage IV osteoarthritis (bone-on-bone) — benefits are limited

Myth 6: "The More Cells, the Better"

Truth: The number of cells matters, but equally important are:

Viability — percentage of live cells after processing (Lipogems® preserves >95%)
Microenvironment — stromal matrix in which cells are delivered
Growth factors — CGF provides prolonged release of PDGF, VEGF, TGF-?

This is why MIBRAR® combines Lipogems® (stem cells + matrix) with CGF (growth factors) — dual regeneration mechanism.

Myth 7: "This Is a Very Painful Procedure"

Truth: The procedure is performed under local anesthesia:

Harvesting adipose tissue — through a 3 mm puncture (like liposuction)
Injection into joint/disc — through a micropuncture 0.3–1.5 mm
Entire procedure — 40–60 minutes, outpatient
Patient goes home the same day

Compare with surgery: general anesthesia, incisions, hospitalization 3–5 days, rehabilitation 3–6 months.

How to Distinguish Real Cell Therapy from Marketing

Ask for the specific product name (Lipogems®, Arthrex ACP, EmCyte, etc.)
Check regulatory status (CE Mark, FDA clearance)
Request follow-up MRI after 3–4 months
Look for the doctor's scientific publications
Avoid clinics promising "100% guarantee"

Frequently Asked Questions

Is it true that stem cells can regenerate cartilage?

Yes, this is confirmed by clinical studies. Mesenchymal stem cells from adipose tissue (SVF) can differentiate into chondrocytes and restore cartilage tissue.

Is stem cell treatment dangerous?

Autologous (own) stem cells are safe — no risk of rejection. Over 25,000+ procedures, MIBRAR® has recorded no serious complications. Allogeneic (donor) cells are less studied.

How soon do stem cells start working?

First improvements — in 2–4 weeks (inflammation reduction). Structural tissue regeneration — 3–6 months. Maximum effect — 6–12 months after the procedure.
