The Biopreservation Group is developing novel preservation technologies for cells and tissues.
The ability to preserve and bank biological entities is critical for scientific and medical applications. We are developing novel preservation technologies for cells and tissue to support the fundamental and practical issues associated with the translation of cell-based and tissue engineering technologies from bench-to bedside.
Our three primary focus areas in biopreservation research are anhydropreservation, cryopreservation by vitrification, and supercooling to sub zero temperature. For these techniques, we are using novel protective strategies to ensure survival in a desiccated, frozen or supercooled state.
Current research projects include:
- Stabilization of mammalian cells at non-cryogenic temperatures in desiccated state
- Development of novel dry-processing techniques for anhydropreservation of cells
- Understanding the bioenergetic, metabolic and transcriptional responses to cryopreservation
- Development of novel microfluidic techniques to preserve rare cells
- Preservation of sperm and oocytes
- Supercooling tissues and organs (liver, heart)
