Human adipose tissue serves as a valuable resource for studying disease mechanisms, offering diverse applications in toxicology and pharmacology. It plays a critical role in modeling chronic diseases like obesity and diabetes, aided by advancements such as organ-on-chip technology and 3D bioprinting. Adipose-derived stem cells are pivotal in regenerative medicine, while models are used extensively for drug screening, studying toxicants, and evaluating endocrine disruptors. Despite challenges like heterogeneity and scalability, collaborative efforts can unlock adipose tissue's full potential in translational research.

Advances in Adipose Tissue
DParit I• Osrgeana-ons-Cehi pM Tecohndoloegyl:s
⚬ Microfluidic platforms that simulate the structure and function of human adipose tissue.
⚬ Allows precise control of the microenvironment, enabling the study of adipose tissue interactions with
other organ systems like the liver (liver-adipose co-culture chips).
⚬ Useful in studying dynamic processes like lipid metabolism, drug response, and inflammation.
Part II
• 3D Bioprinting and Tissue Engineering:
⚬ Using adipose-derived cells to create 3D tissue constructs for in vitro modeling.
⚬ Enables the development of adipose tissue analogs with physiological properties, such as vascularization
and ECM deposition.
⚬ Applications include studying fibrosis, insulin resistance, and tissue regeneration.
Part III
• Co-culture Models:
⚬ Integration of adipocytes with immune cells, endothelial cells, or cancer cells to study cross-talk.
• Examples:
⚬ Adipocyte-macrophage interactions in chronic inflammation and obesity.
⚬ Adipocyte-cancer cell interactions in tumor microenvironments.
⚬ Advances understanding of complex systems like inflammation-driven insulin resistance or tumor growth.
Applications in Toxicology and
PPahrt aI rmacology
• Drug Screening:
⚬ Adipose tissue models are widely used to evaluate drug effects on adipogenesis, lipolysis, and
inflammation.
⚬ Enables identification of off-target effects, such as adipotoxicity or altered endocrine signaling.
⚬ Particularly important for metabolic drugs like anti-diabetics and anti-obesity medications.
Part II
• Environmental Toxicants:
⚬ Adipose tissue acts as a depot for lipophilic toxicants (e.g., pesticides, dioxins).
⚬ Models are used to study the long-term storage and release of toxicants, along with their
effects on lipid metabolism and inflammation.
⚬ Helps assess the impact of environmental pollution on metabolic health.
Part III
• Endocrine Disruptors:
⚬ Adipose tissue models enable studying compounds that interfere with hormonal pathways
(e.g., BPA, phthalates).
⚬ Focus on evaluating their effects on adipocyte differentiation, insulin signaling, and lipid
storage.
⚬ Critical for understanding links between environmental exposures and diseases like obesity or
diabetes.
