Enhancement of neurite adhesion, alignment and elongation on conductive polypyrrole-poly(lactide acid) fibers with cell-derived extracellular matrix

ECMs-coated PLLA-PPy fibers with conductivity of ∼10 S cm−1 was fabricated by electrochemical deposition, L929 cells culture and lysing, and the combination of ECM-CFF with ES could improve the nerve cell adhesion, neurite outgrowth and extension.
