Fig. 3From: Experimental Study of 5-fluorouracil Encapsulated Ethosomes Combined with CO2 Fractional Laser to Treat Hypertrophic ScarCO2 fractional laser promotes permeability through hypertrophic scars in vitro. a The red fluorescence is labeled ethosomes permeated hypertrophic scar tissues after 1, 6, and 24 h in vitro. b The fluorescence intensity of Rhodamine 6GO labeled ethosomes on hypertrophic scar tissue in vitro after 1, 6, and 24 h. ****p value < 0.0001 was considered statistically highly extremely significantBack to article page
