Abstract
Platelet-rich plasma (PRP) is an autologous blood-derived concentrate increasingly utilized in regenerative medicine for its ability to accelerate healing and tissue repair. PRP is broadly classified by leukocyte content, fibrin architecture, and platelet concentration, with classification systems developed to standardize characterization. Preparation methods, including single- or double-spin centrifugation and buffy coat techniques, influence the final composition of PRP, determining the relative proportions of platelets, leukocytes, plasma proteins, and extracellular vesicles. These components act synergistically, with platelets releasing growth factors (e.g., VEGF, PDGF, TGF-β) that stimulate angiogenesis and matrix synthesis, leukocytes providing immunomodulation, plasma proteins facilitating scaffolding, and exosomes regulating intercellular signaling. Mechanistically, PRP enhances tissue repair through four key pathways: platelet adhesion molecules promote hemostasis and cell recruitment; immunomodulation reduces pro-inflammatory cytokines and favors M2 macrophage polarization; angiogenesis supports vascular remodeling and nutrient delivery; and serotonin-mediated pathways contribute to analgesia. These processes establish a regenerative microenvironment that supports both structural repair and functional recovery. Clinically, PRP has been applied across multiple specialties. In orthopedics, it promotes tendon, cartilage, and bone healing in conditions such as tendinopathy and osteoarthritis. In dermatology, PRP enhances skin rejuvenation, scar remodeling, and hair restoration. Gynecology has adopted PRP for ovarian rejuvenation, endometrial repair, and vulvovaginal atrophy. In dentistry and oral surgery, PRP accelerates wound closure and osseointegration, while chronic wound care benefits from its angiogenic and anti-inflammatory effects. PRP has also favored gingival recession coverage, regeneration of intrabony periodontal defects, and sinus grafting. Although preparation heterogeneity remains a challenge, PRP offers a versatile, biologically active therapy with expanding clinical utility.
Summary
PRP의 핵심 작용 기전 (4대 메커니즘)
PRP는 단순한 성장인자 농축물이 아니라, 다음과 같은 다중 기전(multi-mechanism)을 통해 조직 재생을 유도합니다.
혈소판 부착 및 응집
면역조절 (Immunomodulation)
혈관신생 (Angiogenesis)
VEGF, PDGF, TGF-β 분비
미세혈관 재형성 및 영양공급 개선
통증 조절 (Serotonin pathway)
면역조절 + 혈관신생 + 세포신호전달을 포함하는 복합 재생 치료 플랫폼으로 자리매김하고 있습니다.
PRP는 단순한 혈소판 농축 치료를 넘어, 면역조절·혈관신생·세포 신호전달을 아우르는 다중 기전 기반의 재생 치료 플랫폼으로 진화하고 있습니다. 임상적 활용 범위가 지속적으로 확대되는 만큼, 표준화된 제조와 정량적 특성 규명이 향후 치료 신뢰성과 산업적 확장의 핵심이 될 것입니다. 체계적인 기전 이해와 품질 관리가 병행될 때, PRP는 재생의학 분야에서 더욱 중요한 치료 옵션으로 자리매김할 것으로 기대됩니다.
