Gastrodin improves osteoblast function and adhesion to titanium surface in a high glucose environment.

ABSTRACT:

Objective

To investigate the effects of gastrodin on the biological behavior of osteoblasts and osseointegration on the surface of the titanium plate in a high glucose environment, and to explore the possible regulatory mechanisms involved.

Methods

A high glucose-induced oxidative damage model of MC3T3-E1 cells was established in vitro to observe the effects of gastrodin on cellular oxidative stress, cell viability, osteogenic differentiation, mineralization, migration, and adhesion ability on the titanium surface.

Results

High glucose environment can cause oxidative stress damage to MC3T3-E1 cells, leading to a decrease in cell viability, osteogenesis, migration, adhesion and other functions. Gastrodin can upregulate the expression of antioxidant enzymes (Nrf2 and HO-1) and osteogenic differentiation related proteins (RUNX2 and BMP2) in MC3T3-E1 cells in high glucose environment, thereby inhibiting the excessive production of intracellular reactive oxygen species (ROS), reversing the decrease in cell viability, and improving the osteogenic differentiation and mineralization ability of osteoblasts. And gastrodin alleviated the decline in cell migration ability, improved the morphology of the cytoskeleton and increased the adhesion ability of osteoblasts on the surface of titanium plates in high glucose environment. However, gastrodin itself did not affect the cell viability, osteogenic differentiation and mineralization ability of osteoblasts in normal environment.

Conclusions

Gastrodin may protect MC3T3-E1 cells osteogenesis and osseointegration on the surface of the titanium plate in vitro by upregulating antioxidant enzymes expression, and attenuating high glucose-induced oxidative stress. Therefore, gastrodin may be a potential drug to address the problem of poor implant osseointegration in patients with diabetes.

Project description:A critical stage during osseointegration of a titanium (Ti) implant is primary bone remodeling, which involves cross talk among osteoclast precursors, osteoclasts, mesenchymal stem cells (MSCs), and osteoblasts. This phase couples the processes of bone formation and resorption. During remodeling, osteoclasts produce factors capable of regulating MSC migration and osteogenesis. Furthermore, they degrade primary bone, creating a foundation with a specific chemistry, stiffness, and morphology for osteoblasts to synthesize and calcify their matrix. MSCs and osteoblasts receiving cues from the implant surface produce factors capable of regulating osteoclasts in order to promote net new bone formation. The purpose of this study was to determine the effects Ti implant surfaces have on bone remodeling. Human MSCs and normal human osteoblasts (NHOsts) were cultured separately on 15 mm grade 2 smooth PT, hydrophobic-microrough SLA, hydrophilic-microrough Ti (mSLA) (Institut Straumann AG, Basel, Switzerland), or tissue culture polystyrene (TCPS). After 7d, conditioned media from surface cultures were used to treat human osteoclasts for 2d. Activity was measured by fluorescence of released collagen followed by mRNA quantification. This study demonstrates that MSC and NHOst cultures are able to suppress osteoclast activity in a surface dependent manner and osteoclast mRNA levels are selectively regulated by surface treatments. The substrate-dependent regulatory effect was mitigated when MSCs were silenced for integrin subunits and when conditioned media were denatured. These results indicate that MSCs and NHOsts regulate at least two aspects of remodeling: reduced fusion of new osteoclasts and reduced activity of existing osteoclasts.Statement of significanceIn this study, we developed a novel in vitro model to study how microstructured and hydrophilic titanium implants impact bone remodeling for dental and orthopaedic applications. Our approach intersects biomaterials and systems physiology, revealing for the first time that implant surface properties are capable of regulating the communication among the cells involved in remodeling of primary bone during osseointegration. We believe that the basic research presented in our manuscript will provide important knowledge in our understanding of factors that impact implant success. Furthermore, it provides a solid foundation for the development of materials that enable rapid osseointegration and earlier loading times for implants in bone that has been compromised by trauma or disease.
