Abstract
This review explores the dual regenerative and antimicrobial properties of platelet- and marrow-derived biologics, including platelet-rich plasma (PRP), bone marrow aspirate concentrate (BMAC), autologous protein solutions, and plasma fractions. These biologics, widely used in regeneration and tissue repair, offer multiplex bioactivity through growth factors, cytokines, and cellular components that promote healing while reducing infection risk. PRP and BMAC demonstrate significant regenerative effects in musculoskeletal conditions, wound healing, and cartilage repair, with platelets and leukocytes contributing antimicrobial peptides and immune modulation for more indirect regenerative mechanisms. Preparation methods, patient factors, and lack of standardization impact clinical outcomes and efficacy. While promising for reducing reliance on chronic pain medications and improving function, these therapies face limitations including inconsistent preparation and utilization protocols, limited long-term safety data, and regulatory challenges. Here, we review the need for consensus-building, standardized procedures, and robust research to optimize clinical integration and realize the full potential of biologic regenerative therapies in pain medicine.
