Development of methods for cryoconservation

One of the important research areas of CGN is the improvement of efficacy and efficiency for preservation of genetic material in the gene bank.

Research aimed at understanding the changes  that take place  in  and around the cells during freezing and thawing has already led to substantial improvements of cryopreservation methods for semen, embryos  and oocytes of  various species.  In a number of areas, further improvements are needed and seem to be feasible.

CGN Activities

  • Cryopreservation of epididymal semen and research on fertilization results.
  • Optimization of protocols for cryopreservation of poultry, horse, sheep and goat semen
  • Generic improvements in freezing protocols and methods
  • Cryopreservation of embryos:  Measurement of membrane permeability and  mathematical modeling of the optimal freezing rate.
