Article Snippet: The crucial role of mesoscale collagen architecture in establishing and expanding patient-derived tumor organoids is well recognized.. However, obtaining sufficient mesoscale collagen bundles from patient cancer tissues is challenging due to the limited availability of such bundles, which depends on the tumor tissue size and digestion efficiency.. In this study, we employed cellulose microfibers (CMFs) with micron-scale thickness to mimic the mesoscale collagen architecture and developed a biomimetic hydrogel termed MF-gel by combining CMFs with microbial transglutaminase-cross-linked gelatin for culturing lung cancer organoids (LCOs). |
