| Outline of Final Research Achievements |
Relaxin (RLN) is an insulin-like hormone associated with extracellular matrix degradation, osteoclastogenesis, and osteoblast differentiation.This study aimed to assess the effect of RLN during and after lateral expansion of murine calvarial sagittal sutures.RLN was injected topically using a nano-sized liposome carrier into the sagittal sutures of mice just before lateral expansion.
Less collagen staining was observed in the RLN-treated samples after 48 hours. Increased bone mineral density and volume, and thick well-organised osteoid tissue were observed in RLN-treated samples after 1 week. As conclusions, RLN treatment may modify bone remodelling and collagen metabolism during and after suture expansion.
