Targeting cryopreservation-induced cell death: a review

Area of Science:

• Cryobiology
• Cellular Biology
• Biotechnology

Background:

• Cryopreservation is vital for research and therapeutics, but post-thaw cell death (apoptosis and necrosis) significantly reduces viability and function.
• Delayed-onset cell death occurs 6-24 hours post-thaw, posing a major challenge in cryobiology.

Purpose of the Study:

• To review cell death pathways involved in cryopreservation.
• To explore the role of apoptosis and necrosis inhibitors in mitigating cryopreservation-induced cell death.
• To highlight strategies for improving cryopreservation efficiency through targeted inhibition of cell death cascades.

Main Methods:

• Literature review of cryobiology and cell death mechanisms.
• Analysis of apoptosis and necrosis inhibitors (e.g., zVAD-fmk, p38 MAPK inhibitor, ROCK inhibitor).
• Discussion of molecular targets within cell death pathways (caspases, proteases, kinases).

Main Results:

• Apoptosis and necrosis inhibitors significantly reduce cell death post-cryopreservation.
• Inhibitors enhance cell viability and maintain cellular function after thawing.
• Targeting specific molecules in the cell death cascade improves overall cryopreservation efficiency.

Conclusions:

• Incorporating apoptosis and necrosis inhibitors into cryopreservation protocols is a promising strategy.
• This approach effectively combats cryopreservation-induced delayed-onset cell death.
• Improved cryopreservation efficiency has significant implications for regenerative medicine and cell-based therapies.
