EGFR and periodontitis: To investigate whether miR‐5107‐5p suppresses EGFR expression and contributes to EPO‐EVs‐mediated bone regeneration under inflammatory conditions in vivo, we employed Antagomir‐5107 as miR‐5107‐5p specific inhibitor in the periodontitis mice model every 3 days after ligature removal (Figure8A).
