The Application of Duck Embryonic Fibroblasts CCL-141 as a Cell Model for Adipogenesis.

Simple Summary: This study demonstrates that the duck embryo fibroblast cell line CCL-141 can undergo adipogenesis, vital for understanding fat cell development in ducks. Treatments with chicken serum, fatty acids, insulin, and all-trans retinoic acid induced fat cell formation, as evidenced by Oil Red O staining and a gene expression analysis. Moreover, the CRISPR/Cas9 knockout of the adipogenesis gene PPARγ in CCL-141 cells confirmed the cell line's utility for studying adipogenesis-related gene functions. These findings validate CCL-141 as a model for adipogenesis research, which will aid in uncovering its regulatory mechanisms. The duck embryo fibroblast cell line CCL-141, which is currently the only commercialized duck cell line, has been underexplored in adipogenesis research. (1) Background: This study establishes an experimental protocol to induce adipogenesis in CCL-141 cells, addressing the importance of understanding gene functions in this process. (2) Methods: Chicken serum, fatty acids, insulin, and all-trans retinoic acid were used to treat CCL-141 cells, with adipogenesis confirmed by Oil Red O staining and gene expression quantification. CRISPR/Cas9 technology was applied to knockout PPARγ, and the resulting adipogenic phenotype was assessed. (3) Results: The treatments promoted adipogenesis, and the knockout of PPARγ validated the cell line's utility for gene function studies. (4) Conclusions: CCL-141 cells are a suitable model for investigating duck adipogenesis, contributing to the understanding of regulatory factors in this biological process. [ABSTRACT FROM AUTHOR]
