The effectiveness of the HH-chip was demonstrated by simultaneously forming 50 mouse embryonic stem cell-derived embryonic bodies, which sequentially differentiated into 90% beating cardiac spheroids within 15 days of culture on the chip. A comparison of our HH-chip method with traditional hanging-drop and low-attachment plate methods revealed that the HH-chip could generate higher contracting proportions of cardiac spheroids with higher expression of cardiac markers. Additionally, we verified that the contraction frequencies of the cardiac spheroids generated from the HH-chip were sensitive to cardiotoxic drugs.

Enzyme-Linked Immunosorbent Assay (ELISA) as a gold standard approach for fecal calprotectin detection is time-consuming and impractical in point-of-care settings. Moreover, obtaining fecal samples from patients is challenging and inhibits longitudinal monitoring. To address these specific problems, we have developed a novel approach for detecting calprotectin which leverages clustered regularly interspaced short palindromic repeats (CRISPR)/Cas technology. We successfully developed a portable tube-based CRISPR/Cas assay for point-of-care testing of calprotectin. This assay showed a detection range from 1 to 10,000 ng/ml (over 4 log units), using both fluorescent and colorimetric analytical techniques. The established assay was further validated through measurements in mucosal samples obtained in an anesthetised preclinical rodent model of UC, with 2–3 times higher calprotectin concentration detected in UC rat samples compared to that of healthy control animals.

Here, we developed a novel biomimetic blood-gas system (BBGs) for preventing cell damage. This system mimics the cardiac cycle and features an adjustable inspiratory-to-expiratory (IE) ratio to mitigate acidosis caused by continuous oxygen inhalation. In our study, adipose stem cells (ADSCs) were cultured within the circulatory system for 10 min, 2, and 4 h. Compared to the peristaltic pump, the BBGs significantly reduced cell apoptosis and morphological injury while enhancing cell proliferation and adhesion. Additionally, when the supernatant from ADSCs was introduced to LPS-induced macrophages for 24 h, the BBGs group demonstrated a more pronounced anti-inflammatory effect, characterized by reduced M1 macrophage expression. Besides, with isolated rat livers from donation after circulatory death (DCD) perfusion with ADSCs for 6 h by the BBGs, we detected fewer apoptotic cells and a reduced inflammatory response, evidenced by down-regulated TNF-α expression.

Interventions targeting the inflammatory characteristics of atherosclerosis hold promising potential. Although interleukin (IL)-10 is widely acknowledged for its anti-inflammatory effects, systemic administration of IL-10 has limitations due to its short half-life and significant systemic side effects. In this study, we aimed to investigate the effectiveness of an approach designed to overexpress IL-10 in macrophages and subsequently introduce these genetically modified cells into ApoE<sup>−/−</sup> mice to promote atherosclerosis regression. We engineered RAW264.7 cells to overexpress IL-10 (referred to as IL-10M) using lentivirus vectors. The IL-10M exhibited robust IL-10 secretion, maintained phagocytic function, improved mitochondrial membrane potentials, reduced superoxide production and showed a tendency toward the M2 phenotype when exposed to inflammatory stimuli. IL-10M can selectively target plaques in ApoE<sup>−/−</sup> mice and has the potential to reduce plaque area and necrotic core at both early and late stages of plaque progression. Moreover, there was a significant reduction in MMP9, a biomarker associated with plaque rupture, in IL-10M-treated plaques from both the early and late intervention groups. Additionally, the administration of IL-10M showed no obvious side effects.

To mimic the three-dimensional architecture and dynamic expansion and relaxation of the air-blood-barrier, they are grown on a stretchable microphysiological lung-on-chip. For validating the in vitro model, three different protocols have been developed to demonstrate the clinically established anti-inflammatory effect of glucocorticoids to reduce certain inflammatory markers after different pro-inflammatory stimuli: (1) an inflammation caused by bacterial LPS (lipopolysaccharides) to simulate an LPS-induced acute lung injury measured best with cytokine IL-6 release; (2) an inflammation caused by LPS at ALI (air-liquid interface) to investigate aerosolized anti-inflammatory treatment, measured with chemokine IL-8 release; and (3) an inflammation with a combination of human inflammatory cytokines TNFα and IFNγ to simulate a critical cytokine storm leading to epithelial barrier disruption, where the eventual weakening or protection of the epithelial barrier can be measured. In all cases, the presence of macrophages appeared to be crucial to mediating inflammatory changes in the alveolar epithelium.

Double emulsion solvent evaporation is one of the most common techniques to formulate cytokines into vehicles made from hydrophobic polymers; however, the liquid–liquid interfaces formed during emulsification can greatly affect the stability and therapeutic performance of encapsulated cytokines. To develop more effective cytokine-delivery systems, a clear molecular understanding of the interactions between relevant proteins and solvents used in the preparation of such particles is needed. We utilized an integrated computational and experimental approach for studying the governing mechanisms by which interleukin-12 (IL-12), a clinically relevant cytokine, is protected from denaturation by albumin, a common stabilizing protein, at an organic-aqueous solvent interface formed during double emulsification. We investigated protein–protein interactions between human (h)IL-12 and albumin and simulated these components in pure water, dichloromethane (DCM), and along a water/DCM interface to replicate the solvent regimes formed during double emulsification. We observed that (i) hIL-12 experiences increased structural deviations near the water/DCM interface, and (ii) hIL-12 structural deviations are reduced in the presence of albumin. Experimentally, we found that hIL-12 bioactivity is retained when released from particles in which albumin is added to the aqueous phase in molar excess to hIL-12 and sufficient time is allowed for albumin-hIL-12 binding.
