This review explores how platelet- and marrow-derived biologics like PRP and BMAC exhibit both regenerative and antimicrobial properties useful in musculoskeletal conditions and wound healing, though their clinical outcomes are affected by preparation inconsistencies and lack of standardized protocols.

This study found that combining adipose-derived mesenchymal stem cells with platelet-rich plasma improved key healing markers in bowel anastomoses in rats with induced colitis, suggesting potential benefits for anastomosis recovery even in inflamed conditions.

This study reviewed recent advances in regenerative technologies for aesthetic and reconstructive medicine and found that adipose-derived stem cells and platelet-rich plasma are well-established for tissue repair due to their safety and effectiveness, while emerging technologies like exosome-based therapies hold future potential.

This study outlines a hair regrowth treatment targeting hair follicle stem cells, 5-alpha reductase pathway, and microinflammation using PDGF and VEGF, but reports no clinical results.

This review discusses the evolution of platelet concentrates in regenerative medicine, highlighting a proposed function-driven classification that distinguishes three generations of PCs by biological activity rather than development order, with third-generation exosome-based therapies showing superior therapeutic efficacy over earlier formulations.

This review discusses the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

This study found that injecting PDGF-AA and -BB into mouse skin immediately triggered the hair growth cycle's anagen phase, suggesting potential treatment options for certain types of alopecia.

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.

This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.

In this study, researchers developed a chemical cocktail and suspension culture method to transform human dermal fibroblasts into dermal papilla-like cells capable of inducing hair follicle formation in vitro and in vivo.

This study compared porcine-derived placental biomaterials with human-derived counterparts in a rat model of skin injuries and found no significant statistical differences in healing outcomes; however, porcine-derived materials showed reduced early inflammation and faster crust formation, suggesting potential advantages in healing effectiveness.

This study found that photobiomodulation-irradiated conditioned medium from human adipose-derived stromal cells enhanced hair growth in mice, suggesting its potential as a treatment for hair loss by increasing growth factor secretion.

In this multicenter study, adipose-derived stem cell-enriched fat grafting achieved higher satisfaction and better clinical outcomes compared to platelet-rich plasma and hyaluronic acid filler in aesthetic interventions.

This study found that platelet dry powder can be mass-produced from pig blood by adding calcium chloride, resulting in a stable material with high growth factor concentrations, which could enhance supply for industrial product development.

This study found that injectable platelet-rich fibrin (i-PRF) enhances hair follicle regeneration in vitro by promoting human dermal papilla cell proliferation, migration, and trichogenic inductivity, with varying effects depending on concentration.

This review highlights recent findings on blood-derived autologous therapies for skin repair and wound healing but presents no new clinical results, emphasizing future challenges and prospects in regenerative dermatology.

This study reports that human adipose-derived stem cells cultured with platelet lysate instead of fetal bovine serum demonstrate enhanced stress resistance, reduced cellular aging, and faster wound healing in mice, due in part to upregulated stress response and proliferation genes.

This review reports that the treatment of androgenetic alopecia is shifting from single therapies to personalized, multimodal approaches incorporating both traditional and emerging pharmacologics, regenerative strategies, nutraceuticals, cosmeceuticals, and device-based interventions, with combination regimens showing improved outcomes.
