Figure 1. Convergence of MEW (PCL) and extrusion-based bioprinting (gelMA) into a single-step approach A) allows for control over spatial placement of cells. Control over positioning of cells (membrane-labeled eMSCs) while using MEW and extrusion-based bioprinting B) (top view) results in hierarchical structures C) (top view), and the ability to fabricate porous constructs while including MEW D) (top view) and layered distribution in z-direction E) (cross section; arrow indicates where MEW mesh was positioned). eMSCs stained with DiI (red), DiO (blue/yellow), and DiD (green). Scale bars = 400 μm.
