1. Teleost reproduction: Aspects of Arctic char (Salvelinus alpinus) oocyte growth and maturation
Abstract : In all vertebrate species, reproduction is a hormonally controlled process, important for growth and maturation of gonads and germ cells. Production of functional germ cells is of outmost importance to secure the survival of a species. Fish comprises 50% of the known vertebrates and are found in aquatic habitats all over the world.

2. A crystallographic view of egg-sperm interaction
Abstract : Animal reproduction is a heavily studied biological event, however our knowledge regarding the molecular basis of the recognition between gametes – egg and sperm – still remains very incomplete. In particular, it is currently unclear whether protein epitopes important for fertilization have been conserved among different species during evolution, and why gamete interaction proteins generally are subjected to strong positive Darwinian selection.

3. Structural studies of proteins essential for fertilization
Abstract : Where do babies come from? Even though it sounds like a fairly obvious question, it took more than 200 years to discover that sperm, whose first observation dates back to the 17th century, can penetrate into the oocyte and fuse with it. Interestingly, this initial study was carried out in starfish, and since then, scientists have addressed the fascinating question of how gamete recognition functions using very different model systems.
