-
Extracellular vesicles as signaling factors from skeletal muscle cells
We research the role of extracellular vesicles as secreting factors from skeletal muscle, what they contain, and whether they can affect other cells.
Completed research projects
-
Artificial intelligence - a novel tool in assisted reproduction technology
The project aims to improve the methods for selecting sperm and embryos and increase the chance of pregnancy and live-born children.
-
Bacterial components and their effect on energy metabolism in human skeletal muscle cells
Obesity and type 2 diabetes are associated with changes in gut microbiota and disturbed energy metabolism. Is there a crosstalk between gut bacteria and host energy metabolism?
