Hybrid Biofabrication of a Hierarchically Organized Periosteum‐Inspired In Vitro Platform

Advanced Healthcare Materials, EarlyView.
A hybrid biofabrication strategy integrates melt electrowriting with extrusion‐based 3D bioprinting to create a hierarchically organized periosteum‐inspired in vitro platform. Spatially defined osteogenic, fibrous, and endothelial cell‐containing compartments support long‐term culture, osteogenic maturation, and CD31+ endothelial cell organization ...

A 3D‐Printed Model of Human Lactation

Advanced Healthcare Materials, EarlyView.
Breastfeeding supports infant and maternal health, yet in vitro models that mimic human lactation remain scarce. Here, light‐based 3D printing creates high‐resolution, alveoli‐inspired microwells that guide breast cells into polarized microtissues. The printed scaffolds embed slow‐release prolactin microcrystals to deliver hormonal cues, enabling human
