The repair of bone defects that result from periodontal diseases remains a clinical challenge for periodontal therapy. β-tricalcium phosphate (β-TCP) ceramics are biodegradable inorganic bone substitutes with inorganic components that are similar to those of bone. Demineralized bone matrix (DBM) is an acid-extracted organic matrix derived from bone sources that consists of the collagen and matr...

Nonunion is a serious complication of a bone fracture that may occur in any bone of the skeletal system. It occurs when a broken bone fails to heal. Mesenchymal stem cell (MSC)-based tissue engineering technology has been considered an efficient method to improve the healing rate of nonunions. Although previous studies have demonstrated that bone morphogenetic protein 9 (BMP9) is highly capable...

In situ tissue engineering has become a novel strategy to repair periodontal/bone tissue defects. The choice of cytokines that promote the recruitment and proliferation, and potentiate and maintain the osteogenic differentiation ability of mesenchymal stem cells (MSCs) is the key point in this technique. Stromal cell‑derived factor‑1 (SDF‑1) and basic fibroblast growth factor (bFGF) have the ab...

To enhance the understanding of differentiation patterns and bone formation capacity of hESCs, we determined (1) the temporal pattern of osteoblastic differentiation of human embryonic stem cell-derived mesenchymal stem cells (hESC-MSCs), (2) the influence of a three-dimensional matrix on the osteogenic differentiation of hESC-MSCs in long-term culture, and (3) the bone-forming capacity of oste...

BACKGROUND MiR-133 expression is dysregulated in postmenopausal osteoporosis. However, its role in postmenopausal osteoporosis is still not well understood. In the current study, we explore how estrogen deficiency affects miR-133 expression and how miR-133 is involved in osteogenic differentiation of mesenchymal stem cells (MSCs). MATERIAL AND METHODS qRT-PCR analysis was performed to assess ...

Osteoporosis and its complications cause morbidity and mortality in the aging population, and result from increased bone resorption by osteoclasts in parallel with decreased bone formation by osteoblasts. A widely accepted strategy for improving bone health is targeting osteoprogenitor cells in order to stimulate their osteogenic differentiation and bone forming properties through the use of os...

Various stimulators have been reported to promote MSC osteogenic differentiation via different pathways such as bone morphogenetic protein 9 (BMP9) through influencing COX-2 and miR-548d-5p through targeting peroxisome proliferator-activated receptor-γ (PPARγ). Whether synergistic effects between BMP9 and miR-548d-5p existed in promoting osteogenesis from MSCs was unclear. In the study, the pot...

The development of biomaterial surfaces possessing the topographical cues that can promote mesenchymal stem cell recruitment and, in particular, those capable of subsequently directing osteogenic differentiation is of increasing importance for the advancement of tissue engineering. While it is accepted that it is the interaction with specific nanoscale topography that induces mesenchymal stem c...

BACKGROUND Mesenchymal stromal cells (MSCs) are useful for cell therapy because of their potential for multilineage differentiation. However, MSCs that are expanded in traditional two-dimensional (2D) culture systems eventually lose their differentiation abilities. Therefore, we investigated whether azacitidine (AZA) supplementation and three-dimensional culture (3D) could improve the different...

Background: The article aims to review osteogenic differentiation enhancement in human Dental Pulp Mesenchymal Stem Cells (hDPMSCs). Material and Methods: literature was carried out PUBMED with the keywords: (hDPMSCs) differentiation. Conclusions: Many research investigated impact of different compounds on hDPMSCs appliance by which these promote osteogenesis are a potential source for bone reg...
