The First Five Days of a Mouse in GEM, Protein-Free Culture Medium

Foundation scientists are deriving new stem cell lines from fertilized mouse eggs in fully defined, protein-free culture medium, GEM (Gamete Embryo Medium). GEM is a specialized fluid that simulates fluids in the womb. The goal of these experiments is to improve the efficiency of deriving new stem cell lines from testis biopsies. By studying time lapse videos of…
