Hydrogel‐Mediated Preservation of Live Tumor Explants for Drug Development in Peritoneal Metastases

open access: yesAdvanced Materials, EarlyView.
This study presents a hyaluronan‐based hydrogel platform preserving the native tumor microenvironment (morphology, tissue composition, histology) of patient‐derived explants from peritoneal metastases, enabling clinically relevant drug screening. Hydrogel properties such as stiffness and degradation are crucial for longer‐term histoculture.
