The isolation of neonatal rat cardiomyocytes is a time consuming and unpredictable procedure. This study describes methods for cryopreservation and thawing of neonatal rat cardiomyocytes that allows for more efficient use of cells. The thawed NRCMs can be used for various experiments without the need for performing isolations each time.

Here we demonstrate the newly developed I•Cryo kit for mouse sperm cryopreservation. Two-cell stage embryo development with frozen-thawed sperm was improved consistently in 5 mouse strains with the use of this kit. Over a 1.5 year period, 49 genetically modified mouse lines were archived by sperm cryopreservation with the I•Cryo kit and later successfully recovered by IVF.

Preimplantation embryos may be cryopreserved after placement into a hypertonic cryoprotective solution to cause cellular dehydration. After equilibration, ice crystal formation is induced in the solution surrounding the embryo. Further dehydration occurs as the embryo is slowly cooled to subzero temperatures before plunging into liquid nitrogen for storage.

This protocol describes the detailed procedure for cryopreserving human iPS cells in KnockOut SR cryopreservation medium and recovering these cells in complete KnockOut SR Feeder Free (KSR-FF) medium or feeder-based KnockOut SR medium.
FAQs
Controlled cooling manages the transition to low temperature so cryoprotective agents can reduce ice formation and limit damage to cellular structure and function. This balance matters because preservation is not simply a matter of making cells colder. The cooling step establishes conditions that help cells remain usable after storage, supporting later recovery, culture, and expansion in bioengineering workflows.
Rapid thawing returns cells from storage to workable conditions, while dilution removes cryoprotective agents before the cells resume normal culture. These steps connect preservation with recovery: cells are not ready for direct use immediately after storage. Completing the transition prepares them for suitable culture conditions, where researchers can assess recovery and expand the population.
Liquid nitrogen storage greatly slows biochemical reactions and cellular metabolism, allowing preserved cells to remain available over long periods. Its value is therefore connected to time and consistency: laboratories can retain carefully characterized populations until needed rather than relying on continuously maintained cultures. This supports planned experiments, standardized cell banks, and repeatable bioengineering studies.
A typical workflow moves from controlled cooling with cryoprotective agents to liquid nitrogen storage. When cells are needed, researchers rapidly thaw them, dilute the cryoprotectants, and place the cells in suitable culture conditions for recovery. Subsequent expansion provides material for research or manufacturing while maintaining access to a banked, characterized population.
They are useful when work requires access to cells at different times while preserving standardized starting material. The approach supports research, manufacturing, tissue engineering, regenerative medicine, and drug testing. By drawing from cell banks, teams can organize experiments and production around stored, carefully characterized cells and expand them when required.
In bioengineering, cell banks provide a consistent source for experiments involving tissue engineering, regenerative medicine, or drug testing. Long-term storage helps preserve access to characterized populations, while recovery and expansion supply cells for later work. This combination can make experimental timing more manageable and supports standardized comparisons across studies or manufacturing activities.
