Purpose: To investigate the differentiation and osteogenic activity of Naringin-induced bone marrow stromal cells (BMSCs) in dogs.
Methods: BMSCs were separated and cultured in vitro and identified by FCM. Then different concentration of Naringin (1×10⁻⁵, 1×10⁻⁶, 1×10⁻⁷, 1×10⁻⁸ and 1×10⁻⁹ mol/L) were added to cell culture media to induce BMSCs. The effect of Naringin on BMSCs was evaluated respectively by CCK-8 method and measuring the activity of alkaline phosphatase (ALP). The formation of nodules of calcium was detected by von Kossa staining. The data was analyzed with SPSS20.0 software package.
Results: The result of cell-surface marker displayed that the expression of CD34 and CD45 were negative while the expression of CD90 was positive. The values were 0.126%, 0.075% and 95.4%, respectively. Naringin could obviously promote cell proliferation, which exhibited the best effect on proliferation and osteogenic differentiation at concentration of 10-6 mol/L. Calcium nodule (von Kossa) staining was positive.
Conclusions: Naringin-induced bone marrow stromal cells can be differentiated into osteoblasts. Naringin at the concentration of 10-6 mol/L can enhance the proliferation and osteogenic differentiation of BMSCs.

Bone tissue regeneration can be affected by various architectonical features of 3D porous scaffold, for example, pore size and shape, strut size, curvature, or porosity. However, the design of additively manufactured structures studied so far was based on uniform geometrical figures and unit cell structures, which often do not resemble the natural architecture of cancellous bone. Therefore, the aim of this study was to investigate the effect of architectonical features of additively manufactured (aka 3D printed) titanium scaffolds designed based on microtomographic scans of fragments of human femurs of individuals of different ages on in vitro response of human bone-derived mesenchymal stem cells (hMSC).

Bone defects present a significant challenge in orthopedics and trauma surgery, necessitating innovative approaches to stimulate effective bone regeneration. This study investigated the potential of lithium-doped calcium silicate (LiCS) cement to enhance bone regeneration and modulate the immune microenvironment to promote tissue repair. We synthesized a LiCS ceramic powder and performed comprehensive analyses of its physicochemical properties, including phase composition, morphology, setting time, and mechanical strength.

After tooth extraction, alveolar bone absorbs unevenly, leading to soft tissue collapse, which hinders full regeneration. Bone loss makes it harder to do dental implants and repairs. Inspired by the biological architecture of bone, a deformable SIS/HA (Small intestinal submucosa/Hydroxyapatite) composite hydrogel coaxial scaffold was designed to maintain bone volume in the socket.

Introduction: α-Calcium sulfate hemihydrate (α-CSH) is a widely used artificial bone graft material, but it suffers from rapid deterioration and limited osteoinductivity. This study aims to develop composite cements by combining treated dentin matrix (TDM) with α-CSH to enhance osteogenic properties for the healing of bone deformities.
Methods: The composite cements were prepared by mixing treated dentin matrix (TDM) with α-calcium sulfate hemihydrate (α-CSH) and characterized for their mechanical, morphological, and chemical properties using a universal mechanical testing machine, scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier-transform infrared (FTIR) spectroscopy.

Aims: Human periodontal ligament stem cells (hPDLSCs) exhibit an enormous potential to regenerate periodontal tissue. However, their translatability to the clinical setting is constrained by technical difficulties in standardizing culture conditions. The aim was to assess complex culture conditions using a proteomic-based protocol to standardize multi-layer hPDLSC cultivation methodology.
