Stem Cell Related Patent Number US5656479
Title: | Avian embryonic stem cells | Inventors: | Petitte, James N.; Raleigh, NC, USA
Yang, Zengming; Raleigh, NC, USA | Summary: | Described herein are cultured avian embryonic stem cells that have been obtained by growing avian blastoderm cells on a mouse fibroblast feeder cell layer in a medium containing leukemia inhibitory factor. The invention relates to a process of generating undifferentiated avian cells expressing an embryonic stem cell phenotype by collecting the avian cells from an avian blastoderm prior to the formation of the primitive streak, after which the avian cells are deposited in contact with a mouse fibroblast feeder cell layer and grown in the presence of a medium containing leukemia inhibitory factor in a differentiation-inhibiting amount for a time sufficient to produce a sustained avian cell culture. Further disclosed are various cell cultures produced according to this process, and associated veterinary pharmaceutical formulations. | Abstract: | A method of producing undifferentiated avian cells expressing an embryonic stem cell phenotype is disclosed.
