Cellular therapies hold promise to alleviate liver diseases. This study explored the potential of allogenic serum isolated from rat with acute CCl injury to differentiate adipose derived stem cells (ADSCs) towards hepatic lineage. Acute liver injury was induced by CCl which caused significant increase in serum levels of VEGF, SDF1α and EGF. ADSCs were preconditioned with 3% serum isolated from normal and acute liver injury models. ADSCs showed enhanced expression of hepatic markers (AFP, albumin, CK8 and CK19). These differentiated ADSCs were transplanted intra-hepatically in CCl-induced liver fibrosis model. After one month of transplantation, fibrosis and liver functions (alkaline phosphatase, ALAT and bilirubin) showed marked improvement in acute injury group. Elevated expression of hepatic (AFP, albumin, CK 18 and HNF4a) and pro survival markers (PCNA and VEGF) and improvement in liver architecture as deduced from results of alpha smooth muscle actin, Sirius red and Masson's trichome staining was observed.

The liver plays a crucial role in regulating lipid metabolism. Our study examined the impact of Exosomes derived from adipose mesenchymal stem cells (ADSCs-Exo) on lipid metabolism following liver ischemia-reperfusion injury (IRI) combined with partial hepatectomy. We developed a miniature swine model for a minimally invasive hemi-hepatectomy combined with liver IRI.

Article Synopsis
- - This study explores the potential of using adipose-derived stem cells (ADSCs) to create induced hepatocyte-like cells (iHEPs) for treating liver diseases caused by Echinococcus multilocularis.
- - After generating iHEPs through a three-step process, they were transplanted into mice infected with the parasite, and their effectiveness was evaluated through various histological and liver function tests.
- - The findings indicated that iHEPs not only improved liver function and repaired liver damage but also activated important signaling pathways, suggesting they could be a promising treatment for severe liver conditions like hepatic alveolar echinococcosis.

Hepatic ischemia/reperfusion injury (IRI) is an important factor affecting liver regeneration and functional recovery postoperatively. Many studies have suggested that mesenchymal stem cells (MSCs) contribute to hepatic tissue repair and functional recovery through paracrine mechanisms mediated by exosomes. Minipigs exhibit much more similar characteristics of the liver to those of humans than rodents.

Obesity is a multifaceted medical condition characterized by the pathological accumulation of excessive lipids in the body. We investigated the effects of morroniside, a bioactive compound derived from Cornus officinalis, on adipogenesis. We used a preadipocyte 3T3-L1 stable cell line and primary cultured adipose-derived stem cells (ADSCs) in vitro and ovariectomized (OVX) and a high-fat diet (HFD)-fed obese mouse model in vivo.

Background: Gestational diabetes mellitus (GDM) is a highly prevalent disease and poses a significant risk to the health of pregnant women. Abdominal adipose tissue (AT) contributes to insulin resistance (IR) associated with GDM. However, the underlying mechanisms remain unclear.
