Fig 1: Collagen expression in equine MSCs. a Heatmap representation of collagen genes from RNA-sequencing for untreated and TGF-β2-treated equine MSCs. Data shown are Z scores, log2 fold change, and the adjusted p value for each gene for n = 4. b Representative western blot of Col1A1 and ACTB protein expression in untreated and TGF-β2-treated equine MSCs and the densitometric comparison of the relative expression of Col1A1 to ACTB. Data shown are mean ± SD for n = 4, ****p = 0.0001 by a one-tailed t test
