WebAdipocytes, also known as lipocytes and fat cells, are the cells that primarily compose adipose tissue, specialized in storing energy as fat. [1] Adipocytes are derived from mesenchymal stem cells which give rise to … WebAging usually comes associated with increased visceral fat accumulation, reaching even an obesity state, and favoring its associated comorbidities. One of the processes involved in aging is cellular senescence, which is highly dependent on the activity of the regulators of the cell cycle. The aim of this study was to analyze the changes in the expression of p27 …
WebApr 4, 2024 · Liu et al. reveal that glucocorticoids directly induce cellular senescence of bone-marrow adipocytes (BMAds) through a prostaglandin-PPARγ-INK positive feedback loop. The senescent BMAds trigger a secondary senescence in the surrounding bone cells by producing senescence-associated secretory phenotype (SASP) factors, leading to … WebMay 3, 2024 · In this study, we demonstrate that adipocyte senescence is an important pathway in the pathological remodeling of obese adipose tissue.
