Optimized Platelet-Rich Plasma Preparations for a Consistently High Platelet Capture Rate, Bioformulation...

Area of Science:

• Biomedical Engineering
• Hematology
• Regenerative Medicine

Background:

• Platelet-rich plasma (PRP) preparation via centrifugation is crucial for optimal therapeutic outcomes.
• Commercial PRP systems show significant variability in platelet yield and cellular composition.
• Standardized PRP preparation is needed for consistent autologous regenerative medicine applications.

Purpose of the Study:

• To evaluate the performance of the XCELL 60 mL single-spin centrifugation platform for PRP preparation.
• To assess critical PRP performance metrics including platelet concentration, recovery, and cellular composition.
• To compare the efficacy of single-spin versus double-spin centrifugation systems.

Main Methods:

• Evaluation of 70 sequential PRP samples from two clinical facilities using the XCELL 60 mL system.
• Preparation of two distinct PRP types (PRP-1 and PRP-2) based on physician preferences.
• Analysis of platelet concentration, platelet capture rate (PCR), total available platelets (TAPs), hematocrit, and leukocyte content.

Main Results:

• Consistent 8-fold increase in platelet concentration and an average PCR of 83%.
• Significant reduction in red blood cells (<2-6% hematocrit), indicating efficient separation.
• Customizable leukocyte content achieved without compromising platelet yield, demonstrating performance parity with double-spin systems.

Conclusions:

• The XCELL single-spin system provides high-precision platelet recovery and consistent bioformulation.
• Optimized single-spin centrifugation enables standardized therapeutic dosing for regenerative medicine.
• This platform reduces processing time and steps compared to traditional double-spin methods.
