Supercharged Mechanical Stromal-cell Transfer (MEST)

Area of Science:

• Regenerative Medicine
• Biotechnology
• Cell Biology

Background:

• Platelet-rich plasma (PRP) and fat-derived stromal cells are leading methods in regenerative medicine.
• Mechanical processing enhances fat-derived stromal cell applications.
• Combining PRP and stromal cells improves outcomes, but current methods involve separate product mixing.

Purpose of the Study:

• To develop and evaluate a novel method for combining PRP and fat-derived stromal cells.
• To enhance cell yield and viability in regenerative medicine applications.
• To investigate the efficacy of pre-mixing plasma with adipose tissue before mechanical stromal cell isolation.

Main Methods:

• Adipose tissue and blood samples from eight volunteers were used.
• Fat tissue was mixed with platelet-poor plasma (PPP) before mechanical stromal cell isolation using sharp blades.
• Isolated PRP was added to the processed stromal cells, creating a "supercharged" product.
• Cell number and viability were assessed using dual fluoroscopy and statistical analysis.

Main Results:

• The novel method yielded twice the volume and 4.7 times more cells compared to the saline control group (P < 0.001).
• The enhanced cell yield is attributed to the "binding" effect of plasma proteins.
• Utilizing PPP, a "waste product," increased cell count and overall potential efficiency when combined with PRP.

Conclusions:

• The "supercharged" method significantly boosts cell yield and volume by integrating PRP with fat-derived stromal cells early in the process.
• This innovative approach optimizes the use of biological "waste" products like PPP to enhance regenerative therapies.
• Further clinical studies are necessary to validate the clinical efficacy of this novel technique.
