摘要:
The present invention relates to a method for producing avian cell lines, comprising gradual or complete withdrawal of growth factors, serum and/or feeder layer so that the established lines are adherent or nonadherent cells capable of proliferating indefinitely in a basic culture medium. The invention also relates to the cells derived from such lines which are particularly useful for the production of substances of interest.
摘要:
The present invention is related to a method for inducing in vitro the differentiation of stem cells or somatic cells towards germinal cells, comprising the following steps: cultivating said stem cells or somatic cells in a medium allowing their differentiation, and collecting the germinal cells from the culture medium, wherein said cells are cells transformed with an exogenous genetic construction comprising at least a Vasa gene. Germinal cells such as obtained and chimeric animals are also an object of this invention.
摘要:
A culture medium for culturing chicken embryonic stem (ES) cells is disclosed. The culture medium is used for supporting avian ES cell cultures. The components of the avian ES cell media include cytokines, fibroblast growth factors, insulin-like growth factors and stem cell growth factors and anti-retinoic acid antibody. The culture medium is substantially free of active retinoic acid. A method for culturing avian ES cells and the resulting products are also disclosed.

摘要:
The present invention relates to a novel combination of avian cell markers which make it possible to characterize the said cells according to their phenotype, whether they are StX cells, stem cells or germ cells. The present invention also relates to a method for characterizing avian cells with the said markers, and to a method for culturing avian cells, in which the cells are characterized by the method according to the invention.
摘要:
A culture medium for avian embryonic cells and an avian cell culture medium is disclosed. The culture medium is characterized in that it has elements complementary to avian embryonic cells. The complementary elements include insulin-like growth factors and stem cell growth factors. The medium is substantially free of active retinoic acid. A method of culturing avian embryonic cells and the resulting products are disclosed.

The present invention relates to a method for replicating pox viruses such as vaccinia virus comprising the steps of inoculating avian embryonic stem cells with viral particles and culturing said cells in a basal medium until cells lysis occurs and newly produced viral particles are released in said medium.
