We analyzed the expression patterns and localization of HGF and its receptor in skin of white versus brown alpaca.
HGF staining showed strongly positive in the dermal papilla and mesenchymal cells of white alpaca skin.
c-Met staining showed strongly positive in hair matrix and root sheath of brown alpaca skin.
The protein and transcripts possessed the same expression pattern in white and brown alpaca skin.
The results offer theoretical basis for exploration on the role of HGF/c-Met signaling in alpaca.
