Development and analysis of scaffold-free adipose spheroids

Area of Science:

• Biotechnology
• Tissue Engineering
• Cell Biology

Background:

• Adipose tissue is vital in metabolic syndrome, autoimmune diseases, and cancer.
• Traditional 2D monolayer cell cultures inadequately mimic adipose tissue architecture and function.
• 3D models offer improved adipocyte differentiation, lipid droplet accumulation, and cytokine secretion compared to 2D models.

Purpose of the Study:

• To introduce a simple and accessible protocol for generating adipose organoids.
• To provide an improved in vitro model for studying adipose tissue.
• To enable diverse applications in drug testing, toxicology, and tissue engineering.

Main Methods:

• Development of a scaffold-free spheroid model for adipose organoid generation.
• Utilizing either 96-well spheroid plates or agarose micromolds for spheroid formation.
• Isolation, expansion, and characterization of stromal vascular fraction cells.

Main Results:

• The scaffold-free spheroid method offers increased throughput, uniformity, and ease of handling.
• Adipose organoids generated exhibit enhanced structural and functional characteristics compared to traditional models.
• The protocol is adaptable for various experimental needs, with distinct advantages for each method (96-well plate vs. micromold).

Conclusions:

• The developed protocol provides a robust and versatile platform for adipose organoid generation.
• This 3D model serves as a valuable tool for advancing research in metabolic diseases, cancer, and regenerative medicine.
• The scaffold-free spheroid approach represents a significant improvement over existing in vitro adipose tissue models.
