Article Abstract
Osteoporosis, a disease characterized by both loss of bone mass and structural deterioration of bone, is the most common reason for a broken bone among the elderly. It is known that the attenuated differentiation ability of osteogenic cells has been regarded as one of the greatest contributors to age-related bone formation reduction. However, the effects of current therapies are still unsatisfactory. In this study we identify a novel long noncoding RNA which is correlated with osteogenic differentiation and enriched in skeletal tissues of mice. In vitro analysis of bone-derived mesenchymal stem cells (BMSCs) showed that inhibited osteoblast differentiation. In vivo inhibition of by its small interfering RNA rescued bone formation in ovariectomized osteoporosis mice model. Mechanistically, inhibited the nuclear translocation of β-catenin and downregulated the expression of TCF1, LEF1, and Runx2. The results suggest that Lnc- suppresses β-catenin/TCF1/Runx2 signaling and inhibits osteoblast differentiation and bone formation, providing a novel mechanism of osteogenic differentiation and a potential drug target for osteoporosis.

Osteoporotic hip fractures are a considerable cause of pain and disability particularly among the elderly. Osteoporosis causes loss of bone stability, which in turn leads to an increased risk of fractures especially in metaphyseal bone. Moreover, the body's capacity for healing is diminished, resulting in prolonged recovery times following these fractures.

Objective: Progesterone (PG) and its target, progesterone receptor (PGR), are important regulators in inflammatory diseases. This study aimed to investigate the specific role of PG in periodontitis and to elucidate the underlying mechanisms involving PGR.
Methods: Women with periodontitis, including 250 with PG deficiency, 250 with PG supplementation, and 245 controls (normal PG) were enrolled.

Objective: Diabetic foot ulcer (DFU) is a common and serious complication of diabetes, often leading to infection, amputation and poor quality of life. Bone marrow mesenchymal stem cells (BMSCs) have shown promise in treating chronic wounds, but their therapeutic efficacy is limited due to poor survival and low regenerative activity. Low-intensity pulsed ultrasound (LIUS), a non-invasive physical modality, has been shown to enhance the biological behavior of BMSCs.

Human Dental Pulp Stem Cells (hDPSCs) represent a remarkable cell source for tissue engineering and regenerative medicine, offering significant potential for use in personalized medicine and autologous therapies. Decellularized extracellular matrix (ECM)-derived biological scaffolds show excellent properties for supporting cell delivery and growth in both in vitro and in vivo applications. These scaffolds provide essential biochemical cues that regulate cellular functions and offer a more accurate representation of the in vivo environment.

A novel biodegradable bone cement (PSM) was successfully developed through the modification of magnesium oxychloride cement (MOC) with pectin, specifically addressing the inherent limitation of poor water resistance in conventional MOC. Properties of PSM such as washout resistance, setting time, mechanical properties and degradation properties were investigated. Results showed that PSM with 1.
