Abstract
Germline-competent embryonic stem (ES) cells have been successfully derived from mice and rats, but not from other species. Here we report the development of culture conditions for deriving ES cells from chickens and seven other avian species. Chicken ES cells express core pluripotency markers and can differentiate into cells of all embryonic germ layers, as well as extra-embryonic lineages. Notably, chicken ES cells contribute to high rates of chimerism when injected into chicken embryos and give rise to germ cells both in vitro and in ovo, confirming their germline competence. In addition, we demonstrated that ES cell self-renewal pathways are conserved among avian species, allowing ES cells from multiple avian species to be established using optimized chicken ES cell culture conditions. The establishment of authentic avian ES cells lays the groundwork for future applications in genetic engineering and the conservation of avian biodiversity.

Supplemental Material
Primer sequences used in this study.
Contribution of GFP-labeled chicken ES cells to the beating heart of a nonirradiated E4 chicken embryo. Constitutively GFP-expressing chicken ES cells were injected into the subgerminal cavity of a nonirradiated EGK.X-stage chicken embryo and incubated using the surrogate shell system. On day 4, live imaging of green fluorescence was performed.
GFP-labeled donor chicken ES cells contribute to blood vessels and circulating cells in a sublethally irradiated E4 chicken embryo. This video features the same embryo shown in Supplementary Video 3. Constitutively GFP-expressing chicken ES cells were injected into the subgerminal cavity of an EGK.X-stage embryo treated with 500 cGy and incubated using the surrogate shell system. On day 4, live imaging of green fluorescence in the extra-embryonic region was recorded.
GFP-labeled donor quail ES cells contribute to circulating cells in a sublethally irradiated E4 chicken embryo. Constitutively GFP-expressing quail ES cells were injected into the subgerminal cavity of an EGK.X-stage chicken embryo treated with 500 cGy. The embryo was incubated using the surrogate shell system. On day 4, live imaging of green fluorescence in the extra-embryonic region was recorded.
GFP-labeled donor goose ES cells contribute to blood vessels and circulating cells in a sublethally irradiated E5 chicken embryo. Constitutively GFP-expressing goose ES cells were injected into the subgerminal cavity of an EGK.X-stage chicken embryo treated with 500 cGy. The embryo was incubated using the surrogate shell system. On day 5, live imaging of green fluorescence in the extra-embryonic region was recorded.
