Milk and egg yolk are classical components of freezing extenders. However their use is empirical. The aim was 1) to develop an extender to freeze stallion semen, ready to use and of optimized composition; 2) to acquire knowledge in gametes’ cryobiology.
The cryoprotective ability of an extender based on native phosphocaseinate (purified from milk) supplemented with phospholipids (purified from egg yolk) and glycerol was studied both in vitro and in vivo. Post-thaw quality parameters of spermatozoa were analysed by imaging analyses, spectrofluorimetry and flow cytometry. Focus was placed on membrane integrity and phospholipids liposomes were a strong tool to study the interactions between cryoprotectants and cells.
Chemically defined extenders are also an important issue in embryo technology. At UNCEIA I work on maturation and culture systems for bovine oocytes and embryos. The projects I am in charge of can also deal with maternal-embryo exchanges at implantation, cryobiology, or hormonal assays for example.
As a co-creator of a start-up that carries on DNA sexing and diseases detection in birds, I also practise DNA extraction techniques, PCR (nested, multiplex, touchdown) electrophoresis and other biology molecular tools.
