Single-cell atlas of human gingival tissues during healing process after ultrasonic scaling and root planing

ABSTRACT: Objective: To evaluate the composition and function of mural cell populations in human gingival tissues Results: Two mural cell clusters, RGS5+THY1+ and ACTA2+MYH11+ subpopulations, were identified and confirmed by histological staining and cross-validation with three different single-cell RNA sequencing datasets in the GEO database. RGS5+THY1+ cluster in perivascular areas possessed cellular protrusions and exhibited immunomodulatory and synthetic phenotypes. In contrast, the ACTA2+MYH11+ cluster strictly distributed around vessel walls was characterized by a contractile phenotype. Mural cells closely interacted with endothelial cells through PDGF and NOTCH3 signaling. Mural cell loss was detected in the v_i group and in hopeless periodontal teeth, which might be caused by tumor necrosis factor-alpha induced apoptosis.
