Fig. 3From: Generation of a novel human dermal substitute functionalized with antibiotic-loaded nanostructured lipid carriers (NLCs) with antimicrobial properties for tissue engineeringHistochemical analysis of dermal fibroblast cells in the different groups using picrosirius red (for collagen identification) and alcian blue (for proteoglycans). SS: non-functionalized human dermal skin substitutes, FSS: functionalized human dermal skin substitutes containing different types of NLCs (AMK, SCM or CTR) at different concentrations (10, 100, 300 or 1000 µg/ml).
