abstract = {Glioblastoma (GBM) is a devastating brain tumor with
limited treatment success, partly because in vitro models
poorly mimic in vivo complexity. This study introduces a
high-throughput 3D culture platform utilizing modular
starPEG–glycosaminoglycan (GAG) hydrogels that enable
independent control of extracellular matrix (ECM) cues:
stiffness, cytokine affinity, matrix
metalloproteinase-responsive remodeling, and cell
adhesiveness via integrin-binding RGD peptides. This
platform supports encapsulation of patient-derived GBM
cells, recreates physiologically relevant tumor
microenvironments in 384-well plates, and enables automated
drug testing on primary cells. Transcriptomic analyses show
that 3D cultures recapitulate primary and recurrent GBM
programs- including hypoxia-, immune-, and ECM-regulatory
pathways driving growth, invasion, and resistance, without
externally imposed hypoxia. The platform's versatility
extends to drug screening, where single and combinatorial
treatments produce reproducible cytoskeletal and
transcriptomic responses. Notably, the system revealed
dose-dependent reductions in invasive filaments and spheroid
architecture with 5-fluorouracil/uridine and carmustine,
demonstrating its potential for optimizing combinatorial
therapies. This 3D model surpasses 2D cultures, capturing
tumor-specific molecular programs and offering a robust tool
for translational research. Despite lacking vascular or
immune components, its tunability, scalability, and clinical
relevance make it a strong basis for advanced co-cultures.
By delivering reliable, individualized therapeutic data
within a short timeframe, this model holds transformative
potential for personalized GBM treatment.},
