Title: In situ examination of osteoblast biomineralization on sulfonated polystyrene-modified substrates using Fourier transform infrared microspectroscopy

Abstract

Osteoporosis is a skeletal disorder that is characterized by the loss of bone mineral density (BMD) resulting in increased risk of fracture. However, it has been shown that BMD is not the only indicator of fracture risk, as the strength of bone depends on a number of factors, including bone mass, architecture and material properties. We present that physiological mineral deposition requires the formation of a properly developed extracellular matrix (ECM), which recruits calcium and phosphate ions into the synthesis of apatite crystals. Temporal and spatial compositional and structural changes of biological apatite greatly depend on the properties of the crystals initially formed. As such, Fourier-transform infrared microspectroscopy (FTIRM) is capable of examining adaptive remodeling by providing compositional information such as the level of mineralization and carbonate substitution, as well as quality and perfection of the mineral phase. The objective of this study was to evaluate the in vitro mineralization development of MC3T3-E1 murine calvarial preosteoblasts cultured on different substrata by comparing FTIRM measurements from two subclones (mineralizing subclone 4 and nonmineralizing subclone 24) maintained in culture for up to 21 days. The results showed that modulation of the substrate surface using a thin coating of sulfonated polystyrene (SPS) providedmore »« less

The results showed that modulation of the substrate surface using a thin coating of sulfonated polystyrene (SPS) provided favorable conditions for the development of a mineralizable ECM and that the mineral formed by the osteoblasts was similar to that of fully mineralized bone tissue. Specifically, the mineralizing subclone produced significantly more mineral phosphate when cultured on SPS-coated substrates for 21 days, compared to the same culture on bare substrates. In contrast, the level of mineralization in nonmineralizing subclone was low on both SPS-coated and uncoated substrates. The mineralizing subclone also produced comparable amounts of collagen on both substrates; however, mineralization was significantly higher in the SPS culture. The nonmineralizing subclone produced comparable amounts of collagen on day 1 but much less on day 21. Collagen maturity ratio increased in the mineralizing subclone from day 1 to day 21, but remained unchanged in the nonmineralizing subclone. In conclusion, these results suggest that SPS-treatment of the substrate surface may alter collagen remodeling; however, other factors may also influence osteoblast mineralization in the long term.},

Biomineralization of a Self-Assembled Extracellular Matrix for Bone Tissue Engineering

Journal Article Yizhi, M ; Yi-Xian, Q ; DiMasi, E ; ... - Tissue Engineering, Part A

Understanding how biomineralization occurs in the extracellular matrix (ECM) of bone cells is crucial to the understanding of bone formation and the development of a successfully engineered bone tissue scaffold. It is still unclear how ECM mechanical properties affect protein-mineral interactions in early stages of bone mineralization. We investigated the longitudinal mineralization properties of MC3T3-E1 cells and the elastic modulus of their ECM using shear modulation force microscopy, synchrotron grazing incidence X-ray diffraction (GIXD), scanning electron microscopy, energy dispersive X-ray spectroscopy, and confocal laser scanning microscopy (CLSM). The elastic modulus of the ECM fibers underwent significant changes for the mineralizingmore »« less
The aryl hydrocarbon receptor suppresses osteoblast proliferation and differentiation through the activation of the ERK signaling pathway

Journal Article Yu, Haitao ; Du, Yuxuan ; Zhang, Xulong ; ... - Toxicology and Applied Pharmacology

Ahr activation is known to be associated with synovitis and exacerbated rheumatoid arthritis (RA), but its contributions to bone loss have not been completely elucidated. Osteoblast proliferation and differentiation are abnormal at the erosion site in RA. Here, we reported that the expression of Ahr was increased in the hind paws' bone upon collagen-induced arthritis (CIA) in mice, and the levels of Ahr were negatively correlated with bone mineral density (BMD). In addition, immunofluorescent staining showed that the high expression of Ahr was mainly localized in osteoblasts from the CIA mice compared to normal controls. Moreover, the luciferase intensity ofmore »« less

Osteocalcin, a marker of differentiated function during calcification of cultured chick osteoblasts

Conference Lian, J ; Chipman, S ; Glowacki, J ; ... - Fed. Proc., Fed. Am. Soc. Exp. Biol.; (United States)

The expression of differentiated function was examined in cultured osteoblasts isolated from 17-day embryonic chicken calvarie. Cell cultures grown in the absence (control) or presence of 10 mM ..beta..-Glycerol Phosphate (..beta..GP) (stimulus for calcification) were analyzed at 6-day intervals over a 30-day period for total mineral, alkaline phosphatase (AP) activity, osteocalcin levels and collagen. AP was first detected in both cultures between days 6 and 9 when cells became crowded. Control cultures maintained high levels of enzyme activity (30-50 fold) while ..beta.. GPO/sub 4/ culture activity declined after day 18 when extensive mineralization occurred. Osteocalcin, the vitamin K-dependent, bone-specific, calcium-bindingmore »« less
Effects of C-terminal amelogenin peptides on the metabolism of osteoblasts

Journal Article Awada, Tetsuya ; Kunimatsu, Ryo ; Yoshimi, Yuki ; ... - Biochemical and Biophysical Research Communications

Objectives: Amelogenins, enamel matrix proteins secreted by ameloblasts, comprise 90% of the developing extracellular enamel matrix. Recent evidence suggests that amelogenins might induce the proliferation of various cells. However, the residues comprising the active site of amelogenin remain unclear. Therefore, this study aimed to examine the effects of a human amelogenin C-terminal peptide (amgCP) on the metabolism of osteoblasts. Materials and methods: Mouse calvarial osteoblastic cells (MC3T3-E1) were cultured and treated with amgCP. Cell proliferation was measured using MTS and BrdU assays. After confluence was reached, the cells were cultured in osteogenic differentiation medium and treated with 0, 100, ormore »« less

Use of green fluorescent fusion protein to track activation of the transcription factor osterix during early osteoblast differentiation

Journal Article Guangping, Tai ; Christodoulou, Ioannis ; Bishop, Anne E ; ... - Biochemical and Biophysical Research Communications

Osterix (Osx) is a transcription factor required for the differentiation of preosteoblasts into fully functioning osteoblasts. However, the pattern of Osx activation during preosteoblast differentiation and maturation has not been clearly defined. Our aim was to study Osx activation during these processes in osteoblasts differentiating from murine and human embryonic stem cells (ESC). To do this, we constructed an Osx-GFP fusion protein reporter system to track Osx translocation within the cells. The distribution of Osx-GFP at representative stages of differentiation was also investigated by screening primary osteoblasts, mesenchymal stem cells, synoviocytes, and pre-adipocytes. Our experiments revealed that Osx-GFP protein wasmore »« less
