Adipose tissue (AT) can influence whole body homeostasis, therefore understanding the molecular mechanisms of adipocyte differentiation and function is of importance. We provide a protocol for gaining new insights into these processes by analyzing adipocyte homeostasis, differentiation and hypoxia exposure as a model for induced adipocyte apoptosis.

The protocol uses an adipocyte-specific CD63-GFP reporter mouse line to visualize and quantify the secretion of adipocyte-derived extracellular vesicles (EVs) and demonstrate their uptake by progenitor cells, revealing a paracrine pathway within adipose tissue.

In Vitro Mouse Bone Marrow Stromal Cell Differentiation into Adipocytes

This video demonstrates the differentiation of bone marrow stromal cells (BMSCs) into adipocytes. In the two-step process, in the presence of specific growth factors and hormones, undifferentiated BMSCs first differentiate into preadipocytes. The second step involving treatment with glucose and insulin leads to the formation of mature adipocytes with multiple lipid droplets.

Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.

Exogenous Mitochondrial Transfer in Differentiating Brown Adipocytes and AGPAT2-Deficient Preadipocytes
0 Views •
2026
Exogenous mitochondria of human and murine origin can be internalized by differentiating preadipocytes and tracked throughout adipogenic differentiation using imaging and genetic tools. While these mitochondria physically interact with the endogenous mitochondrial network, they do not increase the expression of markers associated with mature brown adipocytes.
FAQs
Insulin shifts adipocytes toward energy storage by increasing glucose uptake and supporting the conversion of glucose and fatty acids into triglycerides. This response packages incoming energy in a form the cells can retain rather than immediately release. Examining that shift helps researchers connect nutrient handling in fat tissue with broader changes in energy balance and insulin sensitivity.
During fasting or sympathetic stimulation, adipocytes activate lipolysis, the breakdown of stored triglycerides into fatty acids and glycerol. These products can leave the storage state and serve as fuels for other tissues. The contrast with insulin-driven storage provides a useful framework for studying how physiological conditions redistribute energy throughout the body.
Adipokines and inflammatory signals make adipose tissue an active regulator of physiology rather than a passive energy depot. By influencing appetite, insulin sensitivity, and immune function, these secreted factors can connect changes within adipocytes to effects in distant tissues. Their signaling role is therefore central when biology studies systemic consequences of altered fat-cell metabolism.
That balance determines whether adipocytes retain energy or release fatty acids and glycerol that can fuel other tissues. It therefore links cellular metabolism with whole-body energy balance, especially as conditions shift between insulin exposure, fasting, and sympathetic stimulation. Tracking this balance helps distinguish storage-dominant from mobilization-dominant physiological states.
Its pathways provide a framework for examining obesity, type 2 diabetes, and metabolic syndrome. Researchers can ask how altered storage, mobilization, adipokine signaling, or inflammatory signals correspond to changes in insulin sensitivity and broader metabolic dysfunction. This makes fat-cell biology relevant to disease mechanisms rather than limiting analysis to body-fat quantity alone.
Because these pathways govern energy storage, fuel mobilization, adipokine signaling, and inflammatory communication, they identify biological processes relevant to metabolic dysfunction. Studying them supports research aimed at improving metabolic health, particularly in obesity, type 2 diabetes, and metabolic syndrome. The goal is to connect cellular mechanisms with measurable whole-body outcomes.
