Mechanosensation is essential for perceiving the external world and social exchange. The skin is our largest sensory organ and is densely populated with nerve endings responsible for senses, such as touch, pain, pressure, and vibration. The molecular and cellular mechanisms underlying the specific types of mechanosensation are well-characterized. Yet, there is limited knowledge about what determines and instructs the branching patterns and proper innervation of somatosensory neurons (SSN) and sensory end-organs in the skin to mediate mechanosensation.

Dr. Metin Uz from CSU CBE and Dr. Hasan Erbil Abaci from Columbia University Dermatology Department have teamed up to address this scientific knowledge gap, and recently received $503,973 of funding for three years from NSF- Chemical, Bioengineering, Environmental and Transport Systems (CBET).

Bringing together the complementary expertise of Dr. Uz and Dr. Abaci, the goal of this collaborative project is to induce and control the level of innervation in engineered skin through spatially-controlled microenvironmental cues, including 3D-patterned dermal extracellular matrix (ECM) conduits, follicular epidermal signals (e.g., hair follicles), and Schwann cells (SCs) differentiated via wireless electrical stimulation in defined patterns.

In the long-term, this project aims to integrate sensory neurons into bioengineered 3D skin constructs (BESCs) to enable studying skin mechanosensation and regeneration using human cells. In a broader sense, the cue-driven strategy involving environmental guidance signals and integrated wireless electrical biointerfaces can further be adapted for spatially-controlled innervation and engineering of other organs.
