Raw Raman Spectra of Minipig Articular Cartilage Across Four Age Stages

Offering raw, uncorrected Raman spectral data of minipig articular cartilage across four distinct developmental stages. Created by Nathan Castro and hosted on Harvard Dataverse, the collection enables the study of biochemical changes in tissue from fetal development through maturity. The data is categorized into four specific age groups: Fetal (day 80), Neonatal, Juvenile, and Mature.

Use Cases

• Classification of tissue maturity using the F7, F14, J, and M age labels
• Identification of biochemical markers in cartilage using Raman spectral peaks
• Benchmarking signal processing algorithms for uncorrected spectroscopic data

Strengths

• Includes rare fetal-stage (day 80) cartilage spectral data
• Provides raw, uncorrected signals allowing for custom baseline subtraction
• Categorized by four distinct biological maturation phases

Limitations

• Raw format requires significant preprocessing and noise reduction before analysis
• Small number of age-based classes may limit high-granularity temporal modeling
• Lack of specific anatomical metadata for the cartilage harvest sites
