The aim of this study is to evaluate the feasibility of hyaluronic acid/sodium alginate (HA/SA) scaffold-based interpenetrating polymeric network (IPN) for the proliferation and chondrogenic differentiation of the human adipose-derived stem cells (hADSCs). The hADSCs cultured in HA/SA IPN scaffold exhibited enhanced cell adhesion and proliferation compared to the HA scaffold. Superior chondrogenic differentiation of hADSCs in HA/SA IPN scaffold, compared to HA-based scaffold, was confirmed by measuring expression levels of chondrogenic markers. These results suggested that HA/SA IPN scaffold could provide a desirable environment for the cell adhesion, proliferation and chondrogenic differentiation of hADSCs.

Cartilage repair remains a critical challenge in orthopaedic medicine due to the tissue's limited self-healing ability, contributing to degenerative joint conditions such as osteoarthritis (OA). In response, regenerative medicine has developed advanced therapeutic strategies, including cell-based therapies, gene editing, and bioengineered scaffolds, to promote cartilage regeneration and restore joint function. This narrative review aims to explore the latest developments in cartilage repair techniques, focusing on mesenchymal stem cell (MSC) therapy, gene-based interventions, and biomaterial innovations.

Urine-derived mesenchymal stromal/stem cells (USCs) could be a valuable source of cells in regenerative medicine because urine can be easily collected non-invasively. In this paper, USCs were isolated from both healthy dogs and dogs affected by chronic kidney disease (CKD), and the efficacy of collection methods (spontaneous micturition, bladder catheterization, and cystocentesis) were compared. Isolated cells were cultured in the presence of platelet-rich plasma and studied for their proliferative capacity (growth curve, doubling time, and colony forming unit), differentiation properties, expression of mesenchymal markers, and Klotho protein.

Introduction: Osteoarthritis (OA) is a degenerative joint disease that can affect the many tissues of the joint. There are no officially recognized disease-modifying therapies for clinical use at this time probably due to a lack of complete comprehension of the pathogenesis of the disease. In recent years, emerging regenerative therapy and treatments with stem cells both undifferentiated and differentiated cells have gained much attention as they can efficiently promote tissue repair and regeneration.

To investigate the effects of artificial light at night on the growth of mandibles in mice and its regulatory mechanisms. A mouse model of artificial light at night (night light pollution group) and normal lighting (normal light group) was established by controlling light exposure time, with 4 mice in each group. Micro-CT was employed to analyze the differences in bone quantities of the mandibles between the two groups.

Objective: To explore the mechanism of hyperbaric oxygen therapy in inhibiting subchondral bone angiogenesis and delaying the progression of osteoarthritis through the PHD2/HIF-1α signaling pathway.
Methods: Mice were randomly divided into three groups (control group, osteoarthritis group, and hyperbaric oxygen treatment group). The effect of hyperbaric oxygen therapy on osteoarthritis was evaluated using Micro-CT, Safranin O-Fast Green staining, and detection of osteoarthritis inflammation markers (MMP-13, ADAMTS-5, Col2a1, and Aggrecan).
