چکیده
A major challenge in the use of HepG2 cell culture models for drug toxicity screening is their lack maturity 2D culture. 3D Matrigel promotes formation spheroids that express liver-relevant markers, yet they still various primary hepatocyte functions. Therefore, alternative matrices where chemical composition and materials properties are controlled to steer maturation remain desired. Herein, a modular approach taken based on fully synthetic minimalistic supramolecular matrix squaramide synthons outfitted with cell-adhesive peptide, RGD spheroid Co-assemblies RGD-functionalized squaramide-based native monomers resulted soft self-recovering hydrogels tunable concentration. self-assembled grown (≈150 µm) within high viability differentiation over 21 days Importantly, significantly higher mRNA protein expression levels phase I II metabolic enzymes, transporters, liver markers found comparison Matrigel. Overall, proven be synthetically accessible effective showcasing potential this rival replace naturally-derived classically used high-throughput screening.

متن کاملSilica bioreplication preserves three-dimensional spheroid structures of human pluripotent stem cells and HepG2 cells
Three-dimensional (3D) cell cultures produce more in vivo-like multicellular structures such as spheroids that cannot be obtained in two-dimensional (2D) cell cultures. Thus, they are increasingly employed as models for cancer and drug research, as well as tissue engineering. It has proven challenging to stabilize spheroid architectures for detailed morphological examination. Here we overcome t...
متن کاملSupramolecular Interfacial Polymerization: A Controllable Method of Fabricating Supramolecular Polymeric Materials
A new method of supramolecular polymerization at the water-oil interface is developed. As a demonstration, an oil-soluble supramonomer containing two thiol end groups linked by two ureidopyrimidinone units and a water-soluble monomer bearing two maleimide end groups are employed. Supramolecular interfacial polymerization can be implemented by a thiol-maleimide click reaction at the water-chloro...
