Influence of F incorporation into the SiO2 matrix was studied during SiOF film deposition using a conventional r.f.
The extracellular calcified matrix deposition was measured using Alizarin Red-S staining.
Matrix deposition was carried out using three different techniques: airbrush (Paasche Airbrush Company, Chicago, IL, USA) coupled with a 75 mL steel container, TM-Sprayer system (HTX Technologies, LLC, Carrboro, NC, USA), and a sublimation apparatus (Chemglass Life Science, Vineland, NJ, USA).
On the other hand, 4 frames with a total of 940 µm2 frame size were used to count glomerular injury (collapse, matrix deposition, thrombi).
We then examined mineralized matrix deposition by 2% alizarin red S (ARS) staining and used an ARS-based spectrophotometric method for quantitative assessment [ 17].
This peripheral nervous system involvement in tissue repair has likewise been shown in the liver, where in this organ, in an experimental model of fibrosis using carbon tetrachloride treatment, chemical denervation significantly reduces matrix deposition and myofibroblastic differentiation [ 14].
Inhibition of BMP activity using the BMP antagonist, noggin, caused a reduction in blastema cell proliferation and a reduction in bone matrix deposition.
Over the period of culture (1 28 d), cells were examined, using immunohistochemical techniques, for the appearance of a range of bone protein markers that assisted in defining the start of matrix deposition and confirmed the synthesis of bone-related proteins.
Similar phenotypic changes were observed using a human prostate epithelium tissue recombination xenograft model, where epithelial cells engineered to overexpress TGF-β1 induced fibrosis and altered matrix deposition concurrent with inflammation in the stromal compartment.
The device, in combination with SIMS imaging, was used to measure matrix crystal size, analyte incorporation to the matrix, and the chemical displacement of the analyte after matrix deposition.
