Culture of Tumorigenic Cells on Protein Fibers Reveals Metastatic Cell Behaviors.

abstract：:Amyloid-like fibrils are prepared from protein in the lab by controlled heat treatments, yet these must be further assembled to match the desirable mechanical and structural properties of biological fibers. Here, β-lactoglobulin fibrils were incorporated into poly(ethylene oxide) fibers of 40-180 nm diameter by electr...
