Modeling of three-dimensional innervated epidermal like-layer in a microfluidic chip-based coculture system

Abstract

Skin-nerve crosstalk is a major element of skin physiological pathology. Here the authors report a 3D innervated epidermal keratinocyte layer as a sensory neuron-epidermal keratinocyte coculture model on a microfluidic chip using the slope-based air-liquid interfacing culture and spatial compartmentalization.
