Cover Story: Three-dimensional scaffolding materials, such as electrospun fibers, have been used for in vitro cell cultures with more representative in vivo results. However, the mechanisms of how such a material modulates intracellular activities remain largely unknown. Here, we investigated the roles of a commonly used scaffold in modulating amino acid levels in hepatocytes. Amino acids play a fundamental role in supporting liver functions such as metabolism. We found that the fibrous scaffold generally upregulated the amino acid contents. Further studies revealed that integrin was the bridge between the extracellular and intracellular conditions. These results open new avenues to better understand cell–extracellular matrix interactions. View this paper
