570. Gelatin-based bioinks and bioresins for advanced light-driven biofabrication

Riccardo Levato (Utrecht University)

invited lecture

Photoresponsive gelatin derivatives are among the most used biomaterials to produce bioink and bioresins for biofabrication. The unique thermoreversible gelation properties of gelatin, combined with covalent crosslinking strategies via the incorporation of i.e. acrylates groups offers a broad range of rheological performances suitable for both extrusion and light-based printing applications....

439. Finetuning the properties of GelMA-dextran aqueous two-phase systems to create unique interconnected porous hydrogels via inkjet 3D printing

podium presentation

Hydrogels with tailored porosity and microstructure are essential for biomedical applications such as drug delivery and tissue engineering. However, controlling their internal architecture remains a challenge. A promising approach leverages polymer phase separation in water to create hydrogels with large interconnected pores, enhancing cell growth or migration, nutrient transport, and cellular...

414. GelMA-Based Hydrogels for in vitro Cholangiocarcinoma Modeling and Drug Testing

Désirée Baruffaldi (Politecnico di Torino)

podium presentation

Introduction
Cholangiocarcinoma (CCA) is a rare but deadly disease that arises from epithelial cells in the liver (intrahepatic) or the biliary tract (extrahepatic). The absence of specific symptoms leads to late diagnosis, which is associated with a poor prognosis due to disease progression, metastasis, and the emergence of drug resistance. The heterogeneity of CCA makes the drug discovery...

337. Towards scaling up two-photon 3D bioprinting of gelatin-based polymers

Silvia Santoni (University of Nottingham)

17/09/2025, 14:30

podium presentation

Introduction
Bioprinting offers the opportunity to reproduce tissue structures in-vitro to support the reconstruction of functional tissue constructs. Among the different bioprinting techniques, two photon polymerization (2PP) allows the generations of the smallest features up to the submicron range. However, the low volume throughput is the main drawback to obtaining constructs of a relevant...

542. Advancing Cartilage Regeneration with Reproducible GelMA Bioinks

Aysu Arslan (BIO INX BV)

podium presentation

Gelatin Methacryloyl (GelMA) is widely used in biofabrication, yet its lack of reproducibility remains a major barrier for translation. This issue originates from a variety of reasons including inconsistent selection of raw materials, variations in modification strategies, varying degrees of substitution, and differences in solvent and photoinitiator concentrations employed in various studies....
