In this study, we investigated the dual-pore kagome-structure design of a 3D-printed scaffold with enhanced in vitro cell response and compared the mechanical properties with 3D-printed scaffolds with conventional or offset patterns. The compressive modulus of the 3D-printed scaffold with the proposed design was found to resemble that of the 3D-printed scaffold with a conventional pattern at similar pore sizes despite higher porosity. Furthermore, the compressive modulus of the proposed scaffold surpassed that of the 3D-printed scaffold with conventional and offset patterns at similar porosities owing to the structural characteristics of the kagome structure. Regarding the in vitro cell response, cell adhesion, cell growth, and ALP concentration of the proposed scaffold for 14 days was superior to those of the control group scaffolds. Consequently, we found that the mechanical properties and in vitro cell response of the 3D-printed scaffold could be improved by kagome and dual-pore structures through DfAM. Moreover, we revealed that the dual-pore structure is effective for the in vitro cell response compared to the structures possessing conventional and offset patterns.

The development of in vitro hepatocyte cell culture systems is crucial for investigating drug-induced liver injury (DILI). One prerequisite for monitoring DILI related immunologic reactions is the extension of primary human hepatocyte (PHH) cultures towards the inclusion of macrophages. Therefore, we developed and characterized an autologous co-culture system of PHH and primary human hepatic macrophages (hepM) (CoC1).

Introduction: Chronic alcohol consumption and tobacco usage are major risk factors for esophageal squamous cell carcinoma (ESCC). Excessive tobacco and alcohol consumption lead to oxidative stress and the generation of reactive carbonyl species (RCS) which induce DNA damage and cell apoptosis. This phenomenon contributes to cell damage and carcinogenesis in various organs including ESCC.

Sepsis, caused by infections, sparks a dangerous bodily response. The transcriptional expression patterns of host responses aid in the diagnosis of sepsis, but the challenge lies in their limited generalization capabilities. To facilitate sepsis diagnosis, we present an updated version of single-cell Pair-wise Analysis of Gene Expression (scPAGE) using transfer learning method, scPAGE2, dedicated to data fusion between single-cell and bulk transcriptome.

Excessive inflammatory responses to viral infections, known as cytokine storms, are caused by overactivation of endolysosomal Toll-like receptors (TLRs) (TLR3, TLR7, TLR8, and TLR9) and can be lethal, but no specific treatment is available. Some quinoline derivatives with antiviral activity were tried during the recent coronavirus disease 2019 (COVID-19) pandemic, but showed serious toxicity, and their efficacy for treating viral cytokine storms was not established. Here, in order to discover a low-toxicity quinoline derivative as a candidate for controlling virally induced inflammation, we synthesized a series of derivatives of amodiaquine (ADQ), a quinoline approved as an antimalarial, and tested their effects on TLRs-mediated production of inflammatory cytokines and cell viability in vitro.

Compared to conventional polymer-based and biomaterial carriers, cells as vehicles for delivering bioactive molecules in the treatment of tumor diseases offer characteristics such as non-toxicity, biocompatibility, low immunogenicity, and prolonged in vivo circulation. However, the focus of current cell drug delivery systems predominantly lies on live cells, such as red blood cells, white blood cells and others. Here, a drug delivery strategy targeting liver cancer utilizing cryo-shocked liver cancer cells (HepG2) as carriers was presented, and non-proliferative HepG2 cells particles loaded with DOX (HepG2-DOX) was effectively prepared, which has good homologous targeting.
