Matrix deposition by ASCs cultured on aligned scaffolds. (A) Immunofluorescent staining for collagen type I (green) found denser collagen fibrils deposited by cells treated with tECM compared to tECM-free group. (B) Hydroxyproline assay showed higher collagen content in the tECM-treated group. Collagen content of each group was normalized to that of the corresponding cell-free group. **p < 0.01; N = 3.
