“…However, higher concentrations (>5 μg/mL) of TA can harm MHs, whereas lower concentrations (<0.1 μg/mL) might not yield positive effects. These findings are consistent with those of our previous study conducted in microfluidic system cultures [ 13 ]. Thus, this condition was subsequently used for further experiments.…”

“…These findings demonstrated that TA exerted positive effects on hepatocyte culture, enhancing both cell viability and function. Furthermore, our finding of the ability of SHs to sustain their functions over an extended period aligns with that of a previous study [ 13 ].…”

“…Tannic acid (TA), which is primarily found in various plants used as food and feed, such as food grains, fruits, wine, and tea [ 13 , 14 ], is a natural polyphenol with diverse therapeutic properties, including antioxidant, antitumor, and anti-inflammatory effects [ 15 ]. The hepatoprotective effects of TA on APAP-induced hepatotoxicity were previously investigated due to its anti-oxidation, anti-inflammation, and anti-apoptosis properties.…”

“…Their study further demonstrated that TA treatment could alleviate hepatotoxicity in APAP-induced mice, ameliorating hepatic dysfunction and mitigating histopathological changes [ 3 ]. Although TA shows promise in anticancer applications, its mechanisms for enhancing hepatic functions in vivo remain unclear [ 13 ]. Furthermore, the dual hepatoprotective and hepatocurative effects of TA remain relatively unexplored.…”

“…Numerous phytoconstituents have been demonstrated to protect against liver diseases in both in vitro and in vivo settings [ 20 ]. However, few of these studies have examined specific components within herbal medicine or their role in facilitating the recovery of liver function, including albumin, following toxin-induced liver injury [ 13 ].…”

This study investigated the effect of tannic acid (TA), a natural plant-derived polyphenol, on hepatocyte viability and function, focusing on both hepatoprotective and hepatocurative aspects within liver failure models. In an in vitro prevention model, the TA-containing group exhibited 1.5-fold and 59-fold higher relative cell viability and albumin synthesis, respectively, in injured mature hepatocytes (MHs) and 1.14-fold and 1.10-fold higher values in injured small hepatocytes (SHs), compared with the TA-free group. In the in vitro curative model, the TA-containing group exhibited 3.25-fold and 113-fold higher relative cell viability and albumin synthesis, respectively, in injured MHs and 0.36-fold and 3.55-fold higher values in injured SHs, compared with the TA-free group. In the in vivo disease model, the administration of 300 μL of 1 μg/mL TA significantly mitigated acute liver failure damage and post-APAP toxicity in mice. This was evident in serum analysis, where the levels of alanine transaminase, aspartate aminotransferase, and total bilirubin notably decreased, in agreement with histological observations. The study findings reveal that TA can enhance hepatic function at specific additive concentrations. Furthermore, even when injured by APAP, hepatocytes could revert to their preinjury state after additional TA supplementation. Additionally, pretreating hepatocytes with TA can alleviate subsequent damage. Thus, TA holds clinical potential in the treatment of APAP-induced liver failure.

This article primarily introduces a new treatment for liver fibrosis/cirrhosis. We developed a hepatic patch by combining decellularized liver matrix (DLM) with the hepatocyte growth factor (HGF)/heparin–complex and evaluated its restorative efficacy. In vitro prophylactic results, the HGF/heparin–DLM patches effectively mitigated CCl4‐induced hepatocyte toxicity and restored the cytotoxicity levels to the baseline levels by day 5. Furthermore, these patches restored albumin synthesis of injured hepatocytes to more than 70% of the normal levels within 5 days. In vitro therapeutic results, the urea synthesis of the injured hepatocytes reached 91% of the normal levels after 10 days of culture, indicating successful restoration of hepatic function by the HGF/heparin–DLM patches in both prophylactic and therapeutic models. In vivo results, HGF/heparin–DLM patches attached to the liver and gut exhibited a significant decrease in collagen content (4.44 times and 2.77 times, respectively) and an increase in glycogen content (1.19 times and 1.12 times, respectively) compared to the fibrosis group after 1 week, separately. In summary, liver function was restored and inflammation was inhibited through the combined effects of DLM and the HGF/heparin–complex in fibrotic liver. The newly designed hepatic patch holds promise for both in vitro and in vivo regeneration therapy and preventive health care for liver tissue engineering.

Liver fibrosis occurs in many chronic liver diseases, while severe fibrosis can lead to liver failure. A chitosan‐phenol based self‐healing hydrogel (CP) integrated with decellularized liver matrix (DLM) is proposed in this study as a 3D gel matrix to carry hepatocytes for possible therapy of liver fibrosis. To mimic the physiological liver microenvironment, DLM is extracted from pigs and mixed with CP hydrogel to generate DLM‐CP self‐healing hydrogel. Hepatocyte spheroids coated with endothelial cells (ECs) are fabricated using a customized method and embedded in the hydrogel. Hepatocytes injured by exposure to CCl4‐containing medium are used as the in vitro toxin‐mediated liver fibrosis model, where the EC‐covered hepatocyte spheroids embedded in the hydrogel are co‐cultured with the injured hepatocytes. The urea synthesis of the injured hepatocytes reaches 91% of the normal level after 7 days of co‐culture, indicating that the hepatic function of injured hepatocytes is rescued by the hybrid spheroid‐laden DLM‐CP hydrogel. Moreover, the relative lactate dehydrogenase activity of the injured hepatocytes is decreased 49% by the hybrid spheroid‐laden DLM‐CP hydrogel after 7 days of co‐culture, suggesting reduced damage in the injured hepatocytes. The combination of hepatocyte/EC hybrid spheroids and DLM‐CP hydrogel presents a promising therapeutic strategy for hepatic fibrosis.
