Looking at the expression of hypertrophic genes, at day 28 collagen type 10 ( COL10 ), a hallmark of hypertrophic phenotype, [ 25 ] showed an almost significantly higher expression compared to day 14, suggesting that a two-week differentiation period of SPH in 96-well plates increased its expression but may not be sufficient to reach a fully hypertrophic stage.
Notwithstanding, the expression of other key hypertrophic markers such as RUNX2 and matrix metallopeptidase 13 ( MMP13) showed a significant or almost significant increase, consistent with the progression of the ECO process.
