研究目的
Investigating changes in bone quality using the Raman spectroscopic technique in a model of disuse osteoporosis induced by sciatic neurectomy in mice.
研究成果
Raman spectroscopy effectively identified chemical changes in bone mineral and matrix content in a mouse model of disuse osteoporosis. The technique provided insights into the mechanisms of bone quality reduction, suggesting its potential as a diagnostic tool for osteoporosis.
研究不足
The study is limited by the use of a mouse model, which may not fully replicate human osteoporosis conditions. The sample size was small, and the study focused on cortical bone, potentially overlooking trabecular bone changes.
1：Experimental Design and Method Selection:
Sciatic neurectomy (NX) was performed in male C57/BL6J mice as a model of disuse osteoporosis, with sham surgery as a control. Raman spectroscopy was used to analyze bone quality.
2：Sample Selection and Data Sources:
Hindlimbs were harvested from mice eight months post-surgery for analysis.
3：List of Experimental Equipment and Materials:
Raman microscope (inVia, Renishaw), single-energy X-ray absorptiometry (DCS-600EX-III; ALOKA), micro-CT system (Scanco Medical μCT35 System).
4：Experimental Procedures and Operational Workflow:
Raman spectra were collected from the anterior cortical surface of the proximal tibia. BMD and micro-CT measurements were performed post-Raman analysis.
5：Data Analysis Methods:
Quantitative analysis of Raman peak intensities, principal component analysis (PCA) of spectral data, and statistical analysis using Student’s t-test.
