Decellularization is a process that involves the removal of cellular material from the tissues and organs while maintaining the structural, functional, and mechanical properties of extracellular matrix. The purpose of this study was to carry out decellularization of rat adipose tissue, diaphragm, and heart by using two different methods in order to compare their efficiency and investigate proliferation profiles of rat adipose-tissue-derived mesenchymal stem cells (AdMSCs) on these scaffolds. Tissues were treated with an optimized detergent-based decellularization (Method A) and a freeze-and-thaw-based decellularization (Method B). AdMSCs were then seeded on scaffolds having a density of 2 × 10 cells/scaffold and AO/PI double-staining and MTT assays were performed in order to determine cell viability. In this study, which is the first research comparing two methods of decellularization of an adipose tissue, diaphragm, and heart scaffolds with AdMSCs, Method A provided efficient decellularization in these three tissues and it was shown that these porous scaffolds were cyto-compatible for the cells. Method B caused severe tissue damage in diaphragm and insufficient decellularization in heart whereas it also resulted in cyto-compatible adipose tissue scaffolds.

A high-fat diet and physical inactivity are key contributors to obesity, predisposing individuals to various chronic diseases, such as cardiovascular disease and diabetes, which involve multiple organs and tissues. To better understand the role of multi-organ interaction mechanisms in the rising incidence of obesity and its associated chronic conditions, treatment and prevention strategies are being extensively investigated. This review examines the signaling mechanisms between different tissues and organs, with a particular focus on the crosstalk between adipose tissue and the muscle, brain, liver, and heart, and potentially offers new strategies for the treatment and management of obesity and its complications.

This study aimed to investigate the temporal accumulation of odor fatty acids (OFAs) in the dorsal subcutaneous adipose tissue, and uncover their dynamic regulatory metabolic pathways from the transcriptomic perspective in lambs from birth to market. Thirty-two Hulun Buir lambs were selected and randomly assigned to four different sampling stages following their growth trajectories: neonatal (day 1), weaning (day 75), mid-fattening (day 150), and late-fattening (day 180) stages. Results indicated that the contents of three OFAs increased progressively as lambs matured, with the most drastic change occurred at mid-fattening vs.

Background/aim: This study aimed to investigate the safety and efficacy of deferoxamine (DFO) pretreated feline adipose tissue derived mesenchymal stem cells (fATMSCs) for the treatment of inflammatory disorders.
Materials And Methods: fATMSCs were isolated from feline adipose tissue and characterized using flow cytometry for surface marker expression and differentiation assays for adipogenic, osteogenic, and chondrogenic lineages. Different concentrations of DFO were used to evaluate its impact on fATMSC activity.

Background/aim: Cancer cachexia is characterized by weight loss with a specific decrease in skeletal muscle and adipose tissue. In Japan, anamorelin, which has a novel mechanism of action, was approved in 2021 for the treatment of cancer cachexia. However, little information is available on its safety in routine clinical care, in particular the occurrence of conduction defects as adverse reactions.
