A wide variety of hydrogels have been proposed for tissue engineering applications, cell encapsulation, and bioinks for bioprinting applications. Cell-laden hydrogel constructs rely on natural hydrogels such as alginate, agarose, chitosan, collagen, gelatin, fibroin, and hyaluronic acid (HA), as well as on synthetic hydrogels such as poloxamers (Pluronics) and polyethylene glycol (PEG). Alginate has become more and more important in the last years, thanks to the possibility to prepare alginate hydrogels suitable for cell encapsulation mainly because of the mild and reversible cross-linking conditions. In this paper alginate will be described in detail with respect to its chemistry, cross-linking behavior, biocompatibility, manufacturing capacity, and possible modifications.

Pancreatic islet transplantation is a crucial treatment for managing type 1 diabetes (T1D) in clinical settings. However, the limited availability of human cadaveric islet donors and the need for ongoing administration of immunosuppressive agents post-transplantation hinder the widespread use of this treatment. Stem cell-derived islet organoids have emerged as an effective alternative to primary human islets.

Objective: Colorectal cancer (CRC) is the second leading cause of cancer-related deaths worldwide. Engineered biomolecules can be used as a targeted tool to deliver drugs directly to tumors that reduce the adverse effects of conventional treatments. We aimed to prepare non-targeted oxaliplatin-loaded chitosan nanoparticles (OXPT-CS NPs) and targeted OXPT-CS NPs decorated with cetuximab single-chain variable fragment (scFv) to send both NPs to epidermal growth factor receptor (EGFR) overexpressing HCT 116 cells, a human colorectal carcinoma cell line, for comparing their cytotoxicity.

Foreign body giant cells (FBGCs) are crucial in the foreign body reaction at the biomaterial-tissue interface, forming through the fusion of cells from the monocyte/macrophage lineage and performing functions such as material degradation and fibrous encapsulation. Yet, their presence and role in biomaterials research is only slowly unveiled. This review analyzed existing FBGC literature identified through a search string and sources from FBGC articles to evaluate the most commonly used methods and highlight the challenges in establishing a standardized protocol.

Usnic acid (UA) is one of the most abundant secondary metabolites of lichens. Its antibacterial, anti-inflammatory, antiviral, and antitumor properties make it one of the few commercially available lichens compounds. Owing to its low solubility it has limited application, for that reason encapsulation in polymeric micelles (UA-PM) has been used to solve this aspect.

Background: Bladder cancer is one of the most common malignancies of the urinary system. Despite significant advances in diagnosis and treatment, the compromised therapeutic effect of chemotherapeutic agents, such as Oxaliplatin (OXA), remains a major clinical challenge. Thus, a combination therapy is required to enhance the OXA's therapeutic effectiveness and improve patient outcomes.
