Abstract This study established a method for isolating large numbers of high-purity osteocytes from high-density bone. Bone fragments derived from mice tibia and femurs were alternately digested with type I collagenase and EDTA nine times, and the digested cells and bone chips (BC) were cultured, digested, and passaged when cells were fully grown. The types of cells obtained were identified by morphology, viable cell counts, alkaline phosphatase staining, and biochemical activity analyses, and specific osteocyte and osteoblast markers were evaluated by quantitative real-time polymerase chain reaction. Our results showed that among the cells obtained from the… More >

Abstract Periodontitis is a type of chronic inflammation in the gingival tissue caused by infectious bacteria colonizing the surface of the teeth, leading to the destruction of tooth-supporting tissues and loss of alveolar bone. Suberoylanilide hydroxamic acid (SAHA), a class of histone deacetylase (HDAC) inhibitor, has the potential to stimulate osteoblast differentiation by acetylating histone proteins, and thus suppressing the expression of adipogenic and chondrogenic genes. However, the effect of SAHA on the differentiation of human periodontal ligament stem cells (hPDLSCs) is yet to be elucidated. Herein, we investigated the effects of SAHA on in vitro More >
