Plant cryopreservation plays an important role in preserving valuable genetic material and supporting large-scale propagation workflows. However, maintaining repeatable freezing conditions across diverse plant cell lines can be challenging.

In this case study, researchers share how controlled-rate freezing supports fabricated seed development, long-term preservation, and scalable plant propagation research.

CASE STUDY PREVIEW

The challenge: preserving diverse plant cell lines

Developing fabricated seed workflows requires reliable cryopreservation methods that maintain cell viability across many plant lines. Traditional freezing methods can introduce variability and reduce preservation confidence during long-term storage.

“Having a good, reliable cryopreservation technique is key.”

RESEARCH APPROACH

The approach: controlled-rate freezing

Researchers evaluated controlled-rate freezing workflows designed to improve repeatability, reduce variability, and support scalable propagation efforts.

The workflow also eliminated the need for liquid nitrogen infrastructure, simplifying installation and day-to-day operation.

Notable finding

Foray Bioscience reported successful cryopreservation results across multiple plant species, including vigorous growth after cryopreservation and long-term culture potential in Douglas fir cell lines.
