Figure Lengend Snippet: Proliferation rate of normal human dermal fibroblast (NHDF) cells as measured via MTT assay. NHDF cells ( a ) were treated with 0.0156–0.5 mg/mL concentrations of DMM-11-encapsulated liposomes, ( b ) were treated with 0.125–0.5 mg/mL concentrations of DMPM-11-encapsulated liposomes, ( c ) were treated with 0.125–0.5 mg/mL concentrations of DMGM-14-encapsulated liposomes for 24 h and 48 h. Cells were incubated with MTT, and the number of viable cells was measured spectrophotometrically at 570 nm. The bars represent the means ± SD of triplicate values for independent experiments. * 0.05 > p > 0.01, ** 0.01 > p > 0.001.

Figure Lengend Snippet: Vessel-like network development in vitro. a Schematic illustration of four stages of developing vessels: single cells, clusters, initial vessels and advanced vessels. The stages for development were manually scored using a percentage scale (0–100 %), where a higher percentage was given to more developed vessel-like networks. b Comparison of vessel development in scaffolds bearing different cell combinations, assessed at different time points in culture.
