Cell-Free Fat Extract (CEFFE) as a Versatile Cell-Free Biologic for Multitissue Regeneration: From Skin and Bone to...

Area of Science:

• Regenerative Medicine
• Biologics
• Tissue Engineering

Background:

• Cell-free fat extract (CEFFE) is an adipose-derived biologic offering a cell-free alternative to stem cell therapies.
• CEFFE delivers growth factors and regulatory proteins, avoiding risks like tumorigenicity and immunogenicity.
• It presents a potent therapeutic option without ethical concerns associated with stem cells.

Purpose of the Study:

• To systematically evaluate the regenerative efficacy of CEFFE across various tissue systems.
• To synthesize the underlying molecular mechanisms, clinical outcomes, and translational challenges of CEFFE.
• To explore CEFFE's potential in musculoskeletal, neural, reproductive, dermal, ocular, and systemic applications.

Main Methods:

• A comprehensive literature review of preclinical and clinical studies from January 2018 to May 2026.
• Analysis of over 55 articles using databases like PubMed, Scopus, and Web of Science.
• Evaluation of CEFFE's efficacy, dosage-response patterns, and molecular pathways.

Main Results:

• CEFFE accelerates tissue repair via antiapoptotic survival, immunomodulation, and ECM remodeling with angiogenesis.
• Evidence shows CEFFE efficacy in intervertebral disc degeneration, corneal neurodegeneration, sepsis, and IVF.
• Clinical trials confirm safety and efficacy in dermatology and superiority over hyaluronic acid for osteoarthritis.

Conclusions:

• CEFFE is a versatile cell-free biologic driving multitissue regeneration.
• Standardized dosing, key-molecule quantification, and large-scale trials are crucial for clinical and commercial success.
• Addressing donor variability is essential to realize CEFFE's full potential.
