This patent is directed towards the culture of avian embryonic stem cells. The patent has two independent claims. The first is a culture medium for avian embryonic stem cells comprising of FGF-2, IGF-1; at least one cytokine selected from LIF, IL-11, IL-6, CNTF, and oncostatin M (OSM)) and c-kit ligand (either mouse or avian.
