Depot-Specific Adipose Biology: Visceral vs Subcutaneous Differential Responses
Visceral and subcutaneous adipose depots differ fundamentally in their developmental origin (splanchnic vs paraxial mesoderm), adrenergic receptor expression (β-AR density higher in visceral), GHR abundance (higher in visceral), inflammatory macrophage burden,

- Visceral and subcutaneous adipose depots differ fundamentally in their developmental origin (splanchnic vs paraxial mesoderm), adrenergic receptor expression (β-AR density higher in visceral), GHR abundance (higher in visceral), inflammatory macrophage burden, adipokine secretion profile, and metabolic fate of secreted fatty acids (portal drainage in visceral vs systemic in subcutaneous). These differences make depot-specific dissection essential in GH-axis adipose research.
- CJC-1295 in DIO mice produces VAT:SAT ratio reduction — a more favourable fat distribution associated with lower metabolic risk — through preferential visceral lipolysis. Depot-specific fatty acid oxidation (β-HAD enzyme activity in VAT vs SAT homogenates), depot-specific HSL Ser-660 phosphorylation by phospho-specific western blot, depot-specific adipocyte size distributions by Adiposoft, and depot-specific inflammatory macrophage burden by flow cytometry characterise the depot-differential response profile.
- Mesenteric adipose — a visceral depot with direct portal venous drainage and high portal NEFA delivery to the liver — deserves separate characterisation from epididymal adipose, given its anatomical position in NAFLD pathogenesis. Portal NEFA flux quantification using hepatic portal-systemic NEFA concentration gradient measurement at cull provides a functional readout of mesenteric adipose lipolytic output.
