BACKGROUND Adipose tissue is a source of stromal and vascular cells suitable for regenerative medical applications. Cell recovery depends on several factors, including the characteristics of the cannula used to harvest tissue. OBJECTIVES The authors assess whether aspiration of superficial layers of adipose tissue performed with a microcannula, rather than a standard cannula, allows for impro...

BACKGROUND The demand for a large amount of osteogenic cells required in bone tissue engineering warranted exploration of a new source of osteoprogenitor cells. Recent studies have demonstrated that adipose-derived stromal cells possess multiple differentiation capacities, including osteogenic potential, as bone marrow mesenchymal stem cells. In the present study, the authors compared the osteo...

Positive energy balance contributes to adipose tissue expansion and dysfunction, which accounts largely for obesity and related metabolic disorders. Thermogenic fat can dissipate energy, activation or induction of which may promote energy balance and address the pressing health issues. Recent studies have shown that stromal vascular fraction (SVF) from white adipose tissue (WAT) can develop bot...

OBJECTIVE MicroRNA (miR)-34a regulates inflammatory pathways, and increased transcripts have been observed in serum and subcutaneous adipose of subjects who have obesity and type 2 diabetes. Therefore, the role of miR-34a in adipose tissue inflammation and lipid metabolism in murine diet-induced obesity was investigated. METHODS Wild-type (WT) and miR-34a(-/-) mice were fed chow or high-fat d...

BACKGROUND Perturbations in abdominal fat secreted adipokines play a key role in metabolic syndrome. This process is further altered during the aging process, probably due to alterations in the preadipocytes (aka. stromal vascular fraction cells-SVF cells or adipose derived stem cells-ASCs) composition and/or function. Since microRNAs regulate genes involved both in development and aging proces...

Isoliquiritigenin (ILG) is a flavonoid derived from Glycyrrhiza uralensis and potently suppresses NLRP3 inflammasome activation resulting in the improvement of diet-induced adipose tissue inflammation. However, whether ILG affects other pathways besides the inflammasome in adipose tissue inflammation is unknown. We here show that ILG suppresses adipose tissue inflammation by affecting the parac...

Traditional adipose tissue transplantation has unpredictable viability and poor absorption rates. Recent studies have reported that treatment with platelet-rich plasma (PRP), adipose-derived stem cells (ASCs), and stromal vascular fraction (SVF) are related to increased survival of grafted adipose tissue. This study was the first simultaneous comparison of graft survival in combination with PRP...
