Studysummary In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

The study demonstrated that misexpression of the transcription factor cDermo-1 in chick embryos induced the formation of dense dermis, ectopic feather buds, and scales, even in normally featherless regions. This indicated that cDermo-1 is a key regulator of early skin appendage development, acting upstream of β-catenin and FGF-10. The research, conducted on 20 chick embryos using a retroviral expression vector, provided insights into the molecular mechanisms of skin morphogenesis and the potential for gene manipulation in influencing skin structure formation.
