Self‐Organization Formation of Multicellular Spheroids Mediated by Mechanically Tunable Hydrogel Platform: Toward Revealing the Synergy of Chemo‐ and Noninvasive Photothermal Therapy against Colon Microtumor

Three‐dimensional (3D) tumor cell culture offers a more tissue‐recapitulating model in cancer treatment evaluation. However, conventional models based on cell‐substrate adhesion deprivation are still of insufficient real tumor mimic. In this work, a novel method is proposed for inducing multicellula...

Zusammenfassung:Three‐dimensional (3D) tumor cell culture offers a more tissue‐recapitulating model in cancer treatment evaluation. However, conventional models based on cell‐substrate adhesion deprivation are still of insufficient real tumor mimic. In this work, a novel method is proposed for inducing multicellular spheroids (MCSs) formation based on hydrogel with tunable microenvironmental properties. Colon tumor cells DLD1 cultured on hydrogel substrate with proper physical stimulation form MCSs via self‐organization. Chemotherapy based on clinical drug and far‐infrared photothermal therapy is evaluated with DLD1 MCSs obtained by this method. The synergism of chemotherapy and noninvasive photothermal therapy based on graphene device is further verified in MCSs model and it is believed this method holds potential in in vitro anti‐tumor strategies evaluation for precision medicine. A novel method for inducing multicellular spheroids (MCSs) formation is proposed based on hydrogel with tunable microenvironmental properties. The synergism of chemotherapy and noninvasive photothermal therapy based on graphene device is further verified in MCSs model and this method holds potential in in vitro anti‐tumor strategies evaluation for precision medicine.
