Engineered Tissues Made from Human iPSC-Derived Schwann Cells for Investigating Peripheral Nerve Regeneration In Vitro.

Peripheral nerves have a limited ability to regenerate and current clinical approaches involving microsurgery give suboptimal recovery. Engineered tissues using aligned cellular collagen hydrogels can be used as in vitro models through the incorporation of human Schwann cells. However, primary human Schwann cells are difficult to obtain and can be challenging to culture. The ability to generate Schwann cells from human-induced pluripotent stem cells (hiPSCs) provides a more reliable cell source for modeling peripheral nerve tissue. Here, we describe protocols for generating hiPSC-derived Schwann cells and incorporating them into 3D engineered tissue culture models for peripheral nerve research.
