DF-1 Cells

DF-1 cells are a continuous cell line derived from chicken embryonic fibroblasts, specifically from East Lansing Line (ELL-0) chickens. The cell line is noted for its lack of endogenous avian leukosis virus, which is a common contaminant in many other chicken cell lines. This characteristic makes DF-1 cells particularly valuable for virology research, especially in studies involving the propagation and genetic manipulation of viruses that infect birds, such as avian influenza and Marek’s disease virus.

In addition to their use in virology, DF-1 cells are utilized in various areas of cellular and molecular biology research. They have a robust growth rate and a fibroblast-like morphology, making them suitable for in vitro experiments that require a stable avian cell environment. These cells have been instrumental in gene expression studies, especially concerning the effects of viral and other genetic elements in avian species. The genetic stability and susceptibility to transfection also make DF-1 an excellent model for studying gene function and regulation in a controlled environment.
