Fig. 6From: Mechanical load-induced H2S production by periodontal ligament stem cells activates M1 macrophages to promote bone remodeling and tooth movement via STAT1Scheme. Mechanical load-stimulated PDLSCs enhance H2S production to promote M1 macrophage polarization under mechanical stimuli via the activation of the STAT1 signaling pathway, which leads to bone remodeling process during tooth movementBack to article page
