Mesenchymal stem cells (MSCS) from chicken fetal liver are multipotent stem cells that can differentiate in vitro into various terminally differentiated cells. The majority of studies have focused on rats and mice now. Reports from other animals are less and analyses on domestic animals are few. In this study, chicken liver-derived MSCs were isolated from 7-day-old embryo of Beijing fatty chickens. Primary liver-derived MSCs were subcultured to passage 15. The surface markers of liver-derived MSCs, CD29, and CD44 were detected by immunofluorescence and the surface markers CD34 and CK19 of hematopoietic progenitor cells/hepatic oval cells were not detected. RT-PCR analysis detected positive expression of CD29, CD44, CD71, and CD73. The growth curves were typically sigmoidal. Liver-derived MSCs of different passages were successfully induced and differentiated into neuronal and osteoblast cells. The results suggest that the MSCs isolated from chicken fetal liver possess similar biological characteristics with those derived from mice, and their multilineage differentiation provides many potential applications.

Background: Mesenchymal stem/stromal cells (MSCs) can regenerate tissues through engraftment and differentiation but also via paracrine signalling via extracellular vesicles (EVs). Fetal-derived MSCs (fMSCs) have been shown, both in vitro and in animal studies, to be more efficient than adult MSC (aMSCs) in generating bone and muscle but the underlying reason for this difference has not yet been clearly elucidated. In this study, we aimed to systematically investigate the differences between fetal and adult MSCs and MSC-derived EVs at the phenotypic, RNA, and protein levels.

Promising preclinical data suggested that bone marrow-derived mesenchymal stem cells (BM-MSC) can reduce hepatic fibrosis and stimulate liver regeneration. Preclinical studies moreover suggested that the immunomodulatory and anti-inflammatory functions of MSCs may reduce hepatic inflammation, improve liver function, and decrease infection incidences which are deemed especially important in the case of acute-on-chronic liver failure (ACLF). Studies in patients with decompensated cirrhosis demonstrated that injection of BM-MSC resulted in an improvement of biochemical tests and led to a survival benefit in ACLF.

Epithelial cell therapies have been at an impasse because of inefficient methods of transplantation to solid organs. Patch grafting strategies were established enabling transplantation of ≥10 organoids/patch of porcine GFP+ biliary tree stem/progenitors into livers of wild type hosts. Grafts consisted of organoids embedded in soft (~100 Pa) hyaluronan hydrogels, both prepared in serum-free Kubota's Medium; placed against target sites; covered with a silk backing impregnated with more rigid hyaluronan hydrogels (~700 Pa); and use of the backing to tether grafts with sutures or glue to target sites.

Mesenchymal stem/stromal cells (MSCs) have been investigated extensively for their immunotherapeutic and regenerative properties, which may differ by cell source. In MSCs harvested from donors matched for sex, age, and body mass index, we compared the proliferative and migration functions of liver-derived MSCs (L-MSCs) and adipose tissue-derived MSCs (A-MSCs) ( = 6 donors each). Cellular senescence was evaluated by senescence-associated beta-galactosidase enzyme activity and expression of senescence-associated secretory phenotype (SASP) factors using real-time quantitative polymerase chain and by western blot assay.

Article Synopsis
- Recent research indicates that the oxidative environment in fibrotic liver reduces the effectiveness of mesenchymal stem cell (MSC) therapy, suggesting that pharmacological pretreatment can enhance their therapeutic potential.
- The study specifically explored whether Vitamin E pretreatment could improve the antifibrotic effects of Wharton's jelly-derived MSCs (WJMSCs) by co-culturing them with injured rat liver cells and monitoring various markers of liver injury.
- Results showed that Vitamin E-pretreated WJMSCs not only rescued injured hepatocytes and decreased fibrosis markers but also demonstrated better integration into the liver compared to untreated WJMSCs, indicating that Vitamin E enhances the durability and efficacy of MSC treatments for liver fibrosis.
