Cryopreserving Human Tissue

Tech ID: 11214 / UC Case 1997-022-0


Method for Cryopreservation of Human Tissue and Cells

Full Description

Freezing is commonly used to preserve human tissue and cells for use in various medical applications, but significant loss of function occurs with current methods.

Researchers at the University of California, Davis have developed a particularly effective method for the cryopreservation of human tissue and cells. The method achieves extraordinarily high viability of cryopreserved tissue and cells by introducing protective molecules at the cellular level using an optimized protocol to ensure viability during freezing and thawing.

Suggested uses

This method is useful for preserving a wide variety of tissues and cells. The researchers have demonstrated that it is effective for preserving pancreatic islet tissue and platelets. This technique also has great potential for cryopreserving organs, as well as various other tissues and cells ranging from corneas to platelets to sperm.


Advantages over current methods include tremendous improvement in viability and function of frozen tissue and cells.
