Chicken cDNA is a fundamental molecular resource for investigating avian gene expression, functional genomics, and comparative developmental biology. Synthesized by reverse transcription of messenger RNA (mRNA), cDNA captures the expressed coding transcript repertoire of the sampled tissue or cells while excluding intronic sequences, making it well suited for downstream molecular analyses. Owing to the evolutionary position of the chicken (Gallus gallus) and its extensively annotated genome, chicken cDNA is widely used in developmental biology, immunology, neuroscience, reproductive biology, musculoskeletal research, and host–pathogen interaction studies. The chicken embryo remains one of the most extensively characterized vertebrate models for studying embryogenesis, organogenesis, and tissue patterning, while adult tissues provide valuable material for investigating tissue-specific gene expression and physiological regulation. Chicken cDNA also supports comparative genomic studies between avian and mammalian species, facilitating the identification of conserved developmental pathways and regulatory networks.
