Novel clinical grade electrospinning methods could provide three-dimensional (3D) nanostructured biomaterials comprising of synthetic or natural biopolymer nanofibers. Such advanced materials could potentially mimic the natural extracellular matrix (ECM) accurately and may provide superior niche-like spaces on the subcellular scale for optimal stem-cell attachment and individual cell homing in regenerative therapies. The goal of this study was to design several novel “nanofibrous extracellular matrices” (NF-ECMs) with a natural mesh-like 3D architecture through a unique needle-free multi-jet electrospinning method in highly controlled manner to comply with good manufacturing practices (GMP) for the production of advanced healthcare materials for regenerative medicine, and …

Aim: Biomaterials that mimic the nanofibrous architecture of the natural extracellular matrix (ECM) are in the focus for stem cell hosting or delivery in tissue engineering of multilayered soft tissues such as skin, mucosa, or retina. Synthetic nanofibers for such ECM are usually produced by single-syringe electrospinning with only one needle-jet at very low production rates of 0.005–0.008 g·min−1. The aim of this study was to utilize a novel industrial needle-free multijet electrospinning device with the potential for mass production of nanofibrous ECM (NF-ECM) exhibiting a controlled three-dimensional (3D) morphology for large-scale applications such as large area skin regeneration in …
