Processing techniques of the adipose tissue: centrifugation vs decantation.

Area of Science:

• Biomaterials Science
• Tissue Engineering
• Regenerative Medicine

Background:

• Adipose tissue processing is a critical step in regenerative medicine and plastic surgery.
• Standard Coleman centrifugation method faces debate, prompting exploration of alternatives.
• Techniques like decantation, filtration, and water jet offer potential advantages.

Purpose of the Study:

• To review and compare clinical evidence for adipose tissue processing techniques.
• Specifically evaluate centrifugation and decantation methods.
• Assess histological data, tropism, and mesenchymal stem cell viability.

Main Methods:

• Comparative analysis of existing literature on adipose tissue processing.
• Evaluation of histological findings related to tissue integrity.
• Assessment of cell viability and functional markers post-processing.

Main Results:

• Centrifugation and decantation exhibit distinct effects on adipose tissue microstructure.
• Differences observed in the maintenance of tissue tropism and vascularity.
• Mesenchymal stem cell populations show varying survival rates depending on the technique.

Conclusions:

• Centrifugation and decantation are not interchangeable processing methods for adipose tissue.
• The choice of technique impacts histological outcomes and cellular viability.
• Further research is needed to optimize processing for specific clinical applications.
