Microstructural Effects of Melt Electrowritten-Reinforced Hydrogel Scaffolds for Engineering Thick Skin Substitutes

ACS Applied Bio Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 25, 2025

Engineering thick skin tissue substitutes resembling the physiochemical and mechanical properties of native is a significant challenge. Melt electrowriting (MEW) powerful technique with capability fabricating highly ordered structures fine fiber diameters, closely replicating extracellular matrix (ECM). In this study, we constructed melt electrowritten porous polycaprolactone (PCL) scaffolds three different geometries by depositing fibers at 0–90 60–120° in mesh structure honeycomb-like orientation to assess effects microstructure on strength scaffold cellular behavior. These were subsequently infilled gelatin hydrogel, encapsulating human dermal fibroblasts (HSFs) umbilical vein endothelial cells (HUVECs). Mechanical tensile tests revealed that honeycomb hybrid PCL/gelatin exhibited greater elongation failure, along an acceptable elastic modulus suitable for applications. All provided cytocompatible microenvironment maintained over 90% cell viability preserved typical morphology. HSFs guided through PCL apical surface, while HUVECs distributed within hydrogel structure. Additionally, HSFs' alignment was regulated geometry. Notably, expression CD31 HUVECs─a key transmembrane protein capillary formation─increased significantly 14 day incubation period. Among those, 0–90° showed greatest upregulation CD31. findings demonstrate microstructural guidance their interaction play crucial role promoting vascularization. conclusion, MEW-gelatin demonstrates potential effectively both physicochemical essential full-thickness substitutes.
