Identification of Grem2⁺ Dental Follicle Stem Cells in Alveolar Bone Homeostasis and Molar Morphogenesis
This study identifies Grem2⁺ dental follicle stem cells as a distinct, endogenous progenitor population essential for alveolar bone homeostasis and molar morphogenesis, revealing that Grem2-mediated regulation of BMP and IGF2 signaling prevents premature stem cell exhaustion and ensures proper bone formation.
