Summary: Encapsulation using GMA-gelatin as matrix material, combined with shaping and chemical crosslinking, successfully achieved microparticle encapsulation of adherent and non-adherent cells. Results showed that over 85% of cells survived under specific photopolymerization conditions and an encapsulation efficiency of around 75% was reached. The study also demonstrated the diffusivity of molecules in the matrix, as well as the proliferation and enzyme release of encapsulated cells in the microparticle matrix.

Summary: Hemoglobin plays a vital role in red blood cells, but when outside of these cells, it can cause adverse effects such as hypertension and nephrotoxicity. The development of hemoglobin-based oxygen carriers (HBOCs) as substitutes for blood transfusions has faced challenges, and so far, no HBOC has been approved by FDA and EMA. However, HBOCs have found successful applications in organ perfusion fluids.

Summary: Heart failure is a critical phase of cardiovascular disease that leads to disability and mortality. Myocardial infarction is a significant cause of heart failure, but its management remains difficult. A 3D bio-printed cardiac patch has emerged as a promising approach to replace damaged cardiomyocytes. In this study, we aimed to improve cell survival inside the bio-3D printed patch by constructing acoustically sensitive nano oxygen carriers. The results showed that the ultrasound-triggered phase transition of nanodroplets and the encapsulation of hemoglobin improved cell survival and cardiac function, making this a potential treatment for myocardial infarction.

Summary: In this study, hydrogels based on gelatin and lignin were fabricated as efficient drug carriers for Ribavirin. The pore structure, viscoelastic behavior, and swelling ability of the hydrogels were significantly influenced by varying lignin content and crosslinker ratio. Increasing the crosslinker content resulted in smaller pores, while increasing the lignin content led to larger pores. Moreover, increasing lignin content in the hydrogel structure enhanced the release rate of Ribavirin.

Summary: A hydrogel carrier was prepared by cross-linking gelatin and dialdehyde starch, and its gelation process, rheological properties, and mechanical properties with different concentrations of dialdehyde starch were investigated. The hydrogel showed adjustable gelation kinetics and good injectability, as well as self-healing and fatigue resistance properties. Additionally, it exhibited pH-dependent controlled-release ability for curcumin.

Summary: A method to completely polymerize hemoglobin almost without unpolymerized hemoglobin was developed in this study. Hemoglobin was adsorbed on anion-exchange resin and polymerized using a crosslinker made from glutaraldehyde and ethylene glycol. The optimized conditions resulted in almost complete polymerization of hemoglobin, and the polymerized hemoglobin did not induce hypertension or pathological changes in mice, offering potential implications for the development of new hemoglobin-based oxygen carriers.

Summary: A straightforward synthetic protocol was developed to anchor disaccharides, maltose and lactose, onto gelatin sponges for specific cell interactions. The resulting decorated sponges maintained their porous structure and showed significant differences in cellular morphology when HepG2 cells were cultured on them. This protocol could provide new insights into the influence of small carbohydrates on cell adhesion and differentiation processes.

Summary: The transplant community is still striving to improve graft quality and recipient prognosis, with a focus on enhancing oxygenation during organ preservation. The addition of HBOCs to traditional preservation protocols has shown promise in providing more oxygen to organs, reducing ischemia-reperfusion injury, and increasing the pool of transplantable donors.

Summary: 3D cell culture is a technique that mimics in vivo environment for cells to grow in vitro. This study proposes two independent 3D cell culture models for different applications. One uses porous spherical structures as carriers to retain cell shape, while the other uses 3D printed silk fibroin structures for directed cell growth. These models have advantages in cell research, such as drug discovery and treatment of neuropathies.

Summary: Various types of hemoglobin-based oxygen carriers have been developed as red blood cell substitutes for treating blood loss. Glutaraldehyde polymerized Hbs have attracted attention due to their ability to expand blood volume and deliver oxygen. However, PEGylation of Hb, while improving safety, also limits clinical application due to their relatively high oxygen affinity.

Summary: An innovative hybrid nanocarrier based on lipid-polymer coupling was proposed and validated for theranostics and multimodal imaging applications. The nanocarrier, prepared using Microfluidics, consists of a core-shell structure with a lipid bilayer enveloping a polymeric chitosan core, capable of co-encapsulating different compounds. The hybrid nanocarriers exhibit monodispersity, structural integrity in different environmental conditions, and high biocompatibility, making them suitable for MRI and Optical applications.

Summary: Cystic fibrosis is a common genetic disease that affects the respiratory system due to dysfunctional CFTR chloride channels. Researchers have developed an in vitro model on a chip to study the disease and guide treatment. The model successfully demonstrates the effects of dynamic flow on cilia distribution and mucus production, distinguishing between CF and non-CF epithelia. This model on a chip shows promise for studying CF and developing therapies.

Summary: The healing of deep skin wounds is a complex process involving the regulation of multiple biological events. The development of bioengineered full-thickness skin models can provide insights into the formation of fibrotic scars and aid in the identification of new drugs and therapeutic approaches. However, the current planar in vitro models lack the complexity of the closure process, and three-dimensional bioengineered models featuring an endogenous extracellular matrix are needed to better replicate the wound healing process.
