Keywords:Biobanking, cell, tissue and organ cryopreservation, controlled rate freezing, freeze-drying, directional freezing, RAMAN-AFM, control of ice formation, cryomicroscopy, (epigenetic) analysis of cryopreservation outcome

Main Research Topics

The research group is focused on the development of safe and efficient cryopreservation protocols as well as novel freezing and thawing equipment for long-term storage and biobanking of cells and tissues

The main research interests of the group include the following:

  • Investigation of optimal freezing and thawing parameters as well as novel low toxic, defined and xeno-free freezing conditions resulting in high viability of a cryopreserved material (clinically relevant cells, tissues and tissue-engineered constructs) and their long-term epigenetic stability
  • Engineering and validation of unique and application-specific cryopreservation equipment with programmable freezing and thawing rates
  • Development of methods and equipment for induction and active control of ice nucleation at specific temperatures including low voltage electro-freezing, power down, electroporation techniques (in cooperation with University of Ljubljana, Slovenia)
  • Development of strategies for the visualization and analysis of ice formation and recrystallization to investigate cell and tissue specific cryopreservation parameters for effective Biobanking (in cooperation with the Hebrew University of Jerusalem, Israel)
  • Microscopy based visualization and analysis of cell and tissue freeze-drying using Linkam FCDS196 cryostage (in cooperation with KNURE, Ukraine)
  • Analysis of biochemical changes occurred during freezing, thawing and freeze-drying using RAMAN microscopy (confocal RAMAN microscope alpha 300RA from WiTec)
  • Cell protection using alginate encapsulation
  • Rheological characterization of novel cryoprotective solutions (CPA) and their impact on cell behavior during pre-treatment, freezing, storage and thawing.
