Reproductive biology (RBU)

About us

What we do

We seek to find the answer to the question: "How do embryos react to their environment and how can we improve embryo development in vitro ".

Embryonic differentiation is investigated with in vivo embryos as a golden standard (maternal interaction), by making use of several animal models (cattle, pigs, horses, human) which yields additional information from a comparative point of view. We have previously shown that bovine embryo differentiation is affected by the culture environment and by the maternal tract.

We have investigated the impact of stress on oocyte quality and spermatogenesis in cattle, with concurrent effects on the resulting blastocysts. We are using transcriptomic and proteomic approaches to identify key signaling molecules in embryo development. We are also focusing on the role of extracellular vesicles as signaling vectors for oocyte, embryo and maternal communication.

From a practical point of view, we are improving methods for oocyte vitrification and semen freezing. To this end, we use knowledge obtained on signaling molecules.
