Additional file 1 of Combination of lyophilized adipose-derived stem cell concentrated conditioned medium and polysaccharide hydrogel in the inhibition of hypertrophic scarring

Additional file 1: Figure S1. The graphical abstract of ADSCC-CM combined with polysaccharide hydrogel: The concentration of therapeutic cytokines in stem cell-conditioned medium was elevated by lyophilization and rehydration. Simultaneously, the ionic molecules in the conditioned medium helped connect the short nanofibers in the polysaccharide hydrogel, forming a semi-solid drug reservoir for scarring’s remission. Figure S2. Freeze-drying of ADSC-CM: (A)Complete lyophilization of ADSC-CM in the tested volume of 10 ml and 15 ml. (B) Comparison of the ADSC-CM weight before and after freeze-drying.
