The pathological expansion of white adipose tissue (WAT) in obesity involves adipocyte hypertrophy accompanied by expansion of collagen-rich pericellular extracellular matrix (ECM) and the development of crown-like structures (CLS). Traditionally, WAT morphology is assessed through immunohistochemical analysis of WAT sections. However, manual analysis of large histological sections is time-consuming, and available digital tools for analyzing adipocyte size and pericellular ECM...

Hyperandrogenemia (elevated testosterone, T) and metabolic dysfunction are hallmarks of polycystic ovary syndrome (PCOS), which can have varying degrees of ovulatory dysfunction. Adipocyte hypertrophy, induced by obesity and hyperandrogenemia, has been suggested to contribute to the systemic low-grade inflammation thought to be one of the drivers leading to reproductive dysfunction in women with PCOS. However, whether hyperandrogenemia and adipocyte hypertrophy per se induce a...
