Cyanidin suppresses autophagic activity regulating chondrocyte hypertrophic differentiation

Cao Z, Huang S, Dou C, Xiang Q, Dong S · Journal of Cellular Physiology

Cyanidin suppressed the hypertrophic markers Runx2 and Col10a1 — the shift that makes engineered cartilage behave like bone — but suppressed the chondrogenic markers Sox9 and Col2a1 alongside them, via reduced autophagy. A reminder that the same compound can look chondroprotective and anti-chondrogenic in one experiment.

Population

Mesenchymal stem cells differentiating toward chondrocytes

Intervention

Cyanidin during chondrogenic and hypertrophic differentiation

Comparator

Untreated differentiating cells

Limitations

Cell culture in a tissue-engineering context, not a model of dietary intake or of osteoarthritis.
