The Claim
High-throughput gene expression analysis using RT-PCR arrays is feasible on small human osteoarthritis cartilage explants (20–40 mg) with low RNA yield (mean 2.5 μg), achieving high reproducibility (average CV 0.66%) and detecting significant gene expression changes after mechanical loading.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
RT-PCR arrays can reliably measure gene expression changes in small pieces of human cartilage from osteoarthritis patients, even when starting with very little RNA, after the tissue is mechanically loaded.

When cartilage is squeezed, cells inside it sense the pressure through special surface proteins, which turn on a chemical signal that changes the activity of hundreds of genes involved in repair and inflammation control. This happens even in tiny pieces of damaged cartilage and produces the same gene patterns every time the tissue is loaded.
What the research says
1 studyScientists squeezed tiny pieces of damaged knee cartilage and found that hundreds of genes changed in a clear, consistent way — proving you can measure gene activity even in very small samples. This means even small bits of damaged cartilage can tell us how they respond to stress.
