The construction of three-dimensional composite fibrous macrostructures with nanotextures for biomedical applications.
Biofabrication 2016 August 27
The development of modern biomedical nanotechnology requires three-dimensional macrostructures with nanotextures to meet the requirements for practical applications in intricate biological systems. Additionally, the restoration and regeneration of some specific body tissues and organs rely on the function of conductive polymers, which can provide electrical cues for cells. In this study, we fabricated three-dimensional composite nanofibre macrostructures of polycaprolactone (PCL) with different concentrations of polyaniline (PANi) by employing an improved electrospinning technology with a specially designed collector. The 3D structures possessed cap-like macrostructures with centimetre-scale thickness and interconnected pore nanotextures with nanometre-scale nanofibres. To estimate the biocompatibility of the 3D PCL/PANi composite nanofibre macrostructures, mouse myoblasts (C2C12 cells) were cultured as model cells. The initial responses of C2C12 cells to the 3D PCL/PANi composite macrostructures were significantly superior to those to pure PCL, that is, the cells exhibited typical myoblast-like morphologies with obvious pseudopodia and the moderate incorporation (less than 2.0 wt%) of conductive PANi facilitated cell proliferation, which indicated that PANi has appreciable cell affinity. Moreover, the addition of conductive PANi to the 3D composite nanofibre macrostructures considerably enhanced myoblast differentiation and myotube maturation. These results suggest that electrospun 3D PCL/PANi composite nanofibre macrostructures would have promising applications in tissue engineering.
