Comparison of Transforming Growth Factor-Beta 1 Levels in Platelet Rich Plasma Using Pure and Buffy Coat Methods in a Healthy Population

The researchers reported that freeze-dried collagen-activated platelet-rich plasma increased transforming growth factor-β1 levels compared to non freeze-dried PRP with collagen, suggesting a potential benefit for tissue regeneration.

This study found that while both buffy coat and apheresis PRP improved androgenetic alopecia, the buffy coat method was linked to greater patient-reported improvement despite having lower platelet counts.

This study found that both buffy coat and apheresis PRP are effective for treating androgenetic alopecia, with buffy coat PRP associated with higher patient-reported improvement despite lower platelet counts.

The study suggests that variability in platelet-derived growth factors in PRP is influenced by both patient-to-patient differences and the devices used for PRP preparation, contributing to inconsistent clinical outcomes in hair loss treatments.

PRP preparation partially activates platelets, causing varied growth factor release.
