Periostin is upregulated in the connective tissue of the oral mucosa after injury. Gingivectomy surgeries were performed in rats, and periostin was assessed using specific antibodies. At 1 day post-surgery, periostin immunoreactivity is evident in the periodontal ligament (PDL) and in the connective tissue at the edge of the wound (black arrow). By day 3, periostin protein is evident in the developing granulation tissue, with increased immunoreactivity on day 7.
