The efficacy of a scaffold-free Bio 3D conduit developed from human fibroblasts on peripheral nerve regeneration in a rat sciatic nerve model - Fig 1

<p>A: The pre-designed 3D tube-like structure. The green spheres represent homogeneous multicellular spheroids that were developed using only human normal dermal fibroblasts. B: The Bio 3D conduit according to the pre-designed 3D model. The conduit was cannulated via a 18-gauge intravenous catheter (SURFLO: NIPRO, Osaka, Japan). Scale bar = 10 mm.
