HDFs embedded within both modalities of advanced dressings showed moderate expression of COL1A1, COL1A2 and COL3A1 relative to GAPDH, without variations over time. The expression of fibronectin was high in both dressing types (RNA from the 11-day construct was lost), whereas the expression of COL4A1 and COL4A2 was low. There were no significant changes in gene expression over time and no differences between the two dressing modalities.
