Cryopreserved vs. Fresh Cells:
Know the Difference
Why the method of preparing stem cells matters more than you think.
Lab Expansion Ensures Healthier MSCs
Many clinics isolate and immediately freeze unexpanded MSCs, which stresses the cells and impairs function. Survival rates often hover just above 70% viability.
Dr. Yi’s teams culture cord-derived MSCs to healthy proliferation, reaching around 94% viability before freezing. After thawing, these MSCs retain ≥85% viability—far exceeding common benchmarks.
Cryopreserving After Expansion: A Tactical Edge
Dr. Yi states, “Freezing cells post-expansion—not immediately after isolation—preserves their integrity.” Flash-freezing uncultured cells locks in stress-induced damage, undermining their therapeutic utility.
SCTE’s post-expansion freezing allows cells time to stabilize and recover, blending the accessibility of cryostorage with the efficacy of fresh cells.
Grounded in Tradition & Science
“Stem cells should awaken the body’s healing intelligence, not act as pharmaceuticals.”
