简介
Tissue engineering scaffolds should ideally mimic the natural ECM in structure and function. Electrospun nanofibrous scaffolds are easily fabricated and possess a biomimetic nanostructure. Scaffolds can mimic ECM function by acting as a depot for sustained release of growth factors. bFGF, an important growth factor involved in tissue repair and mesenchymal stem cell proliferation and differentiation, is a suitable candidate for sustained delivery from scaffolds. In this study, we present two types of PLGA nanofibers incorporated with bFGF, fabricated using the facile technique of blending and electrospinning (Group I) and by the more complex technique of coaxial electrospinning (Group II). bFGF was randomly dispersed in Group I and distributed as a central core within Group II nanofibers; both scaffolds showed similar protein encapsulation efficiency and release over 1–2 weeks. Although both scaffold groups …
