Liver tissue engineering aims at the possibility of reproducing a fully functional organ for the treatment of acute and chronic liver disorders. Approaches in this field endeavor to replace organ transplantation (gold standard treatment for liver diseases in a clinical setting) with in vitro developed liver tissue constructs. However, the complexity of the liver microarchitecture and functionality along with the limited supply of cellular components of the liver pose numerous challenges. This review provides a comprehensive outlook onto how the physicochemical, mechanobiological, and spatiotemporal aspects of the substrates could be tuned to address current challenges in the field. We also highlight the strategic advancements made in the field so far for the development of artificial liver tissue. We further showcase the currently available prototypes in research and clinical trials, which shows the hope for the future of liver tissue engineering.

Background: We aim to comprehensively analyze and validate the prognostic efficacy of tetraspanin 4 (TSPAN4) and several other migrasome-related markers in hepatocellular carcinoma (HCC).
Methods: The expression, diagnostic, and prognostic efficacy of five migrasome-related genes in HCC were analyzed using several databases. Five pairs of adjacent non-tumor tissues and HCC tissues were used to validate the expression.

This study attempts to prove that the antioxidant effect of fucoxanthin nanoparticles can prevent streptozotocin-induced rat liver damage. Fucoxanthin nanoparticles are synthesized using the high-energy ball milling method. Dynamic Light Scattering (DLS) was then used to describe the sizes of the fucoxanthin nanoparticles.

Obesity, often driven by high-fat diets (HFD), is a major global health issue, necessitating effective preventive measures. Tetragonia tetragonoides, a plant with known medicinal properties, has not been extensively studied for its effects on HFD-induced obesity and related genetic changes in mice. This study explores the impact of Tetragonia tetragonoides extract (TTE; 300 mg/kg) on obesity-related traits in C57BL/6J male mice, with a focus on transcriptomic changes in the liver and white adipose tissue (WAT).
