Design and characterization of cationic SAPs.

Notes: (A) Fabrication of HGF-loaded cationic SAP/heparin (SAP/Hep-HGF) gel for β-cell transplantation. (B) Determination of the diameter of SAP nanofibers by DLS. (C) Evaluation of the gel formation of SAPs (5 mg/mL). (D) TEM micrographs of SAP solution (0.5 mg/mL). (E) SEM micrographs of SAP hydrogel (5 mg/mL). The scale bar is 500 nm (D) and 1 μm (E), respectively. The magnification is 8,000× (D) and 10,000× (E), respectively.

Abbreviations: K, lysine; L, leucine; D, aspartate; R, arginine; SAP, self-assembling peptide; HGF, hepatocyte growth factor; DLS, dynamic light scattering; TEM, transmission electron microscope; SEM, scanning electron microscope; PBS, phosphate-buffered saline.
