Overview

Integrative analyses reveal key cellular mechanisms driving horn development in goats, highlighting evolutionary insights.

Key Points

  • This research aims to elucidate the cellular programs involved in postnatal horn bud development in goats.
  • Integrated histological, bulk, and single-cell transcriptomic analyses
  • Functional assays to assess osteogenic potential of identified progenitor cells
  • Cross-species analysis to compare horn and antler development
  • Identification of ZEB2+ progenitor mesenchymal cells initiating horn-specific osteogenesis.
  • Dermal lineage cells showed significant expansion and activation by postnatal day 7.
  • Distinct signaling interactions observed between keratinocytes and osteogenic cells promoting mineralization.
