Effects of long-term cryopreservation at -80 °C on the viability and recovery of peripheral blood stem cells.
OBJECTIVES Ensuring the long-term stability of cryopreserved peripheral blood stem cells (PBSCs) is critical for optimal patient outcomes. However, it remains unclear how long-term cryopreservation at -80 °C without controlled-rate freezing in a mechanical freezer affects these cells. Temperature changes may damage cel...
