Stem Cell Related Patent Number US5340740
| Title: | Method of producing an avian embryonic stem cell culture and the avian embryonic stem cell culture produced by the process | | Inventors: | Petitte, James N.; Raleigh, NC, USA
Yang, Zengming; Raleigh, NC, USA | | Summary: | Described herein is a method of culturing avian embryonic stem cells, uses and advantages thereof. The invention relates to a process by which avian blastoderm cells are grown on a mouse fibroblast feeder cell layer in a medium containing a leukemia inhibitory factor, such that undifferentiated avian cells expressing an embryonic stem cell phenotype are produced. Further disclosed are methods by which avian cells are collected 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 leukemia inhibitory factor in a differentiation-inhibiting amount for a time sufficient to produce a sustained avian cell culture. Associated veterinary pharmaceutical formulations are also provided. | | Abstract: | A method of producing undifferentiated avian cells expressing an embryonic stem cell phenotype is disclosed.
