Reproduction biology of lynx – basic research for conservation breeding of Iberian lynx

Functional biodiversity of cells belonging to the reproductive system

Bat immunology

• Molecular and biochemical analysis of hormones and other factors involved in reproduction (e.g. gamete maturation, fertilization and gestation)
• Functions and physiological adaptations of specific cells and structural units of the reproductive system and their in vitro 2D and 3D culture
• Recombinant expression of proteins relevant for reproduction and their functional analysis
