The differentiation of periodontal ligament (PDL) progenitor cells is important for maintaining the homeostasis of PDL tissue and alveolar bone. Vitamin C (VC), a water-soluble nutrient that cannot be biosynthesized by humans, is vital for mesenchymal stem cells differentiation and plays an important role in bone remodeling. Therefore, the objective of this(More)
Estrogens and their receptors are important factors involved in periodontal ligament (PDL) tissue health. As a regulator of estrogen receptors (ER), the proline-, glutamic acid-, and leucine-rich protein 1 (PELP1) may play a role in alveolar bone formation and PDL homeostasis. The aim of the present study was to observe PELP1 expression in rat PDL tissue(More)
BACKGROUND Osteogenic induction and bone formation are heavily affected by environmental factors, including estrogen, estrogen receptors, and coregulatory proteins, such as the recently reported proline-, glutamic acid-, and leucine-rich protein 1(Pelp1). OBJECTIVE To investigate Pelp1 expression in rat bone mesenchymal stem cells (rBMSCs) during cell(More)
OBJECTIVE Collagen peptides (CP) compounds, as bone health supplements, are known to play a role in the treatment of osteoporosis. However, the molecular mechanisms of this process remain unclear. This study aimed to investigate the effects of bovine CP compounds on the proliferation and differentiation of MC3T3-E1 cells. METHODS Mouse pre-osteoblast cell(More)
PURPOSE Collagen peptides (CPs) and calcium citrate are commonly used as bone health supplements for treating osteoporosis. However, it remains unknown whether the combination of oral bovine CPs with calcium citrate is more effective than administration of either agent alone. METHODS Forty 12-week-old Sprague-Dawley rats were randomly divided into five(More)
The main objective of this paper is to develop an integrated Microsoft ASP.NET/JavaScript prototype for interactively building up virtual environments from existing geographical information system (GIS) databases that include Landsat images, spatial vector data and digital elevation map (DEM). This prototype takes advantage of both the ASP.NET and(More)
