摘要: An injectable nanofibrous hydrogel scaffold integrated with growth factors (GFs) loaded polysaccharide nanoparticles was developed that specifically allows for targeted adipose-derived stem cells (ASCs) encapsulation and soft tissue engineering. The produced via biological conjugation of biotin-terminated star-shaped poly(ethylene glycol) (PEG-Biotin) streptavidin-functionalized hyaluronic acid (HA-Streptavidin). were noncovalently assembled electrostatic interactions between low-molecular-weight heparin (LMWH) N,N,N-trimethylchitosan chloride (TMC). Vascular endothelial factor (VEGF) entrapped in the LMWH/TMC by affinity LMWH.
