To explore the molecular mechanism of hair follicle apoptosis in the goat hair cycle, single-cell transcriptome sequencing was performed on 8214 hair follicle cells in the Anagen period, Catagen period, and Telogen period. We identified 9 cell types and found that Matrix cells ( MCs ) enriched the Wnt signaling pathway and apoptosis-related genes. Further studies revealed the key dynamic genes ( such as KRT19, API5 ) and regulatory factors ( such as MSX2, LEF1 ) that determine the fate of MCs. This study mapped a high-resolution cell map of goat hair follicle apoptosis, providing new insights and diagnostic biomarkers for programmed cell death.
