Figure 1. Preparation and characterization of I-ADF at four dilution ratios. (A) ADF was cut into small fragments and mixed with physiological saline at the four dilution ratios; (B) Gross morphology of I-ADF at the four dilution ratios; (C) H&E staining of I-ADF formulations; (D) Masson’s trichrome staining of I-ADF formulations. Scale bars are shown in each micrograph in (C and D) and represent 100 μm. ADF: Adipose-derived matrix film; I-ADF: injectable adipose-derived matrix film fragments; H&E: hematoxylin and eosin.
