Fresh vs Frozen Stem Cells: What Patients Should Understand

Whether the cells are prepared fresh or thawed from cryopreservation affects timing, viability, and handling.

Key takeaways

  • Fresh and thawed-from-frozen are both used.
  • Viability should be documented at delivery.
  • Cold-chain transport matters.
  • Ask which type you are receiving.

Fresh cells

Fresh cells are prepared close to delivery time. Timing and lab proximity matter for viability.

Cryopreserved cells

Cells stored frozen are thawed before use. The cold-chain and thaw protocol affect quality.

Documented viability

Ask for the viability percentage at the time of delivery — not just at production.

Patient question

'Will I receive fresh or thawed cells, and what is the documented viability?' is a simple, direct, important question.
