Where the science makes a difference
From a single cell to a living ecosystem, explore the applications of low-temperature biology.
Organ Transplantation
Cold storage and machine perfusion support transplantation. Researchers are exploring longer preservation through supercooling, vitrification, and improved warming.

Banking stem cells helps coordinate collection, research, and treatment. Preserving differentiation potential and biological activity matters alongside survival.
Related concepts: Recovery, cell identity, function
Explore the related lessonCancer & Cell Therapy
Cryopreservation supports the storage and transport of some therapeutic immune-cell products. Each product needs evidence of retained biological activity.
Related concepts: Functional assays, CPA exposure
Explore the related lessonBlood & Immune Cell Banking
Selected blood components and immune-cell populations can be banked using methods suited to their biology. Not every component is stored in the same way.
Related concepts: Cell-specific methods, recovery
Explore the related lessonTissue Engineering
Engineered tissues need their cells, three-dimensional organization, and matrix to remain useful after preservation.
Related concepts: CPA penetration, tissue structure
