Effects of multiwalled carbon nanotubes on electrospun poly(lactide-co-glycolide)-based nanocomposite scaffolds on neural cells proliferation.

The repair of nerves remains a major challenge in neuron-regeneration. In this study, poly(lactic-co-glycolic acid)/multi-walled carbon nanotubes (PLGA/MWCNTs) nanofibrous scaffolds were fabricated by electrospinning method. The surface morphology, physical, and mechanical properties were characterized through scanning electron microscopy (SEM), transmission electron microscopy, and tensile tests, respectively.

Potential Neurogenesis of Human Adipose-Derived Stem Cells on Electrospun Catalpol-Loaded Composite Nanofibrous Scaffolds.

Catalpol, a natural active ingredient extracted from the traditional Chinese medicine, was verified exhibiting beneficial effects on neural differentiation compared with commonly used chemical inducers by our previous studies. The aim of this study was to evaluate the effects of catalpol-loaded scaffold on guiding neuronal differentiation of human adipose tissue-derived stem cells (hASCs). Fabrication technique of catalpol loading into the electrospun poly(lactic-co-glycolic acid)/multi-walled carbon nanotubes/silk fibroin nanofibrous scaffolds was successfully established.
