3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

Advanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

3D Bioprinted Alginate-Gelatin-Collagen Based Hydrogels Laden With Fibroblast and Keratinocyte Cells Show Potential for Regeneration of Injured Skin. [PDF]

Macromol Biosci
Engineered skin tissue by 3D bioprinting of hydrogels comprising alginate‐gelatin‐collagen and laden with human dermal fibroblasts and keratinocytes were successfully produced. The viability and phenotypes of the fibroblasts and keratinocytes were all well maintained within the printed constructs using MTT, live/dead and immunofluorescence assays.
