Fresh vs Frozen
Fresh vs frozen cell products
Both fresh and cryopreserved cells are used in regenerative medicine. What matters is documentation and handling, not marketing labels.
Compare
Two formats
Fresh
Cells administered shortly after processing. Requires tight scheduling, careful logistics and release testing within the use window.
Frozen (cryopreserved)
Cells stored in vapor-phase liquid nitrogen and thawed before use. Requires validated cryoprotectant, thaw protocol and post-thaw viability data.
Was viability measured before administration?
What is the post-thaw viability for frozen products?
What is the storage temperature and duration?
Is the cold chain documented?
