Microtubes with gradient decellularized porcine sciatic nerve matrix from microfluidics for sciatic nerve regeneration.

Long-range peripheral nerve defect is a severe and worldwide disease. With the increasing development of tissue engineering, the excellent ability of nerve extracellular matrix (ECM) in peripheral nerve injury (PNI) has been widely studied and verified. Here, we present a novel microtube that contains gradient decellularized porcine sciatic nerve ECM hydrogel (pDScNM-gel) from microfluidics for sciatic nerve regeneration.
