MicroRNAs (miRNAs) are small non-coding RNAs involved in the regulation of gene expression. MiR-1908 is a recently identified miRNA that is highly expressed in human adipocytes. However, it is not known what role of miR-1908 is involved in the regulation of human adipocytes. In this study, we demonstrate that the level of miR-1908 increases during the adipogenesis of human multipotent adipose-derived stem (hMADS) cells and human preadipocytes-visceral. Overexpression of miR-1908 in hMADS cells inhibited adipogenic differentiation and increased cell proliferation, suggesting that miR-1908 is involved in the regulation of adipocyte cell differentiation and metabolism, and, thus, may have an effect on human obesity.
The induction of adipose thermogenesis plays a critical role in maintaining body temperature and improving metabolic homeostasis to combat obesity. β3-adrenoceptor (β3-AR) is widely recognized as a canonical β-adrenergic G-protein-coupled receptor (GPCR) that plays a crucial role in mediating adipose thermogenesis in mice. Nonetheless, the limited expression of β3-AR in human adipocytes restricts its clinical application.
Immune cell infiltration into adipose tissue (AT) is a key factor in type 2 diabetes (T2DM). However, research on the impact of fat distribution on immune cells and immune responses in women is still lacking. This study used enrichment, protein-protein interaction network, immune cell infiltration, and correlation analysis to compare the similarities and differences between the transcriptome data of visceral AT (VAT) and subcutprotein-proteinaneous AT (SAT) obtained from the omprehensive database of gene expression in women with non-T2DM and T2DM.

In obesity, C-C chemokine ligand 2 (CCL2) plays a critical role in recruiting macrophages to white adipose tissue (WAT), contributing to chronic inflammation. In this study, we sought to explore the effects of fish oil (FO) on CCL2 expression and histone (H3K27)-modifying enzymes in both human model of preadipocytes and primary adipose-derived stem cells (ASCs). Present findings in preadipocytes lineage evidenced that lipopolysaccharide (LPS) increased (∼5.
Background: Intrauterine adhesion (IUA), resulting from uterine trauma, is one of the major causes of female infertility. Previous studies have demonstrated that endometrial mesenchymal stem cells (eMSC) have therapeutic effects on IUA through cellular secretions. It is particularly true for most of the pre-clinical experiments performed on multiple animal models, as human-derived eMSC cannot maintain long-term engraftment in animals.
Hematopoietic stem cells (HSCs) reside in a milieu that supports their functions, differentiation, and survival. This niche consists of several types of cells, including mesenchymal stem/stromal cells, endothelial cells, osteoblasts, megakaryocytes, macrophages, adipocytes, lymphoid cells, and nerve fibers. The interactions between these cells and HSCs have a role in HSC fate.
