口腔微生物组对于维持口腔健康至关重要。不平衡的口腔微生物导致牙周病和其他疾病。目前尚不清楚口腔微生物群是否影响口腔干细胞的功能。这项研究使用了一种常见的临床抗生素治疗方法来改变口腔微生物组生态,并检查口腔间充质干细胞(MSC)是否受到影响。我们发现口腔微生物组的改变导致牙龈MSC缺乏,导致雄性小鼠伤口愈合延迟。口腔微生物群释放脂多糖(LPS)刺激microRNA-21(miR-21)的表达,然后通过miR-21/Sp1/端粒酶逆转录酶途径损害牙龈MSC的正常功能和伤口愈合过程。这是第一项研究表明雄性小鼠口腔微生物组和MSC稳态之间的相互作用。干细胞2018;36:551-561
Oral microbiome is essential for maintenance of oral cavity health. Imbalanced oral microbiome causes periodontal and other diseases. It is unknown whether oral microbiome affect oral stem cells function. This study used a common clinical antibiotic treatment approach to alter oral microbiome ecology and examine whether oral mesenchymal stem cells (MSCs) are affected. We found that altered oral microbiome resulted gingival MSCs deficiency, leading to a delayed wound healing in male mice. Mechanistically, oral microbiome release lipopolysaccharide (LPS) that stimulates the expression of microRNA‐21 (miR‐21) and then impair the normal function of gingival MSCs and wound healing process through miR‐21/Sp1/telomerase reverse transcriptase pathway. This is the first study indicate that interplay between oral microbiome and MSCs homeostasis in male mice. Stem Cells 2018;36:551–561
