Introduction: Peripheral nerve damage causes loss of quality of life due to loss of function. An innovative and promising solution has been the "nerve guide conduits" (NGC) that morphologically must mimic the characteristics of the extracellular matrix to enhance nerve regeneration. Objective: To gather and describe the main features that should...

Cellular behavior in nerve regeneration is affected by the architecture of the polymeric nerve guide conduits (NGCs); therefore, design features of polymeric NGCs are critical for neural tissue engineering. Hence, the purpose of this scoping review is to summarize the adequate quantitative/morphometric parameters of the characteristics of NGC that...
