This study found that urotensin II promoted proliferation and VEGF secretion in rat dermal papilla cells by activating the Wnt-β-catenin signaling pathway, with the effect being reversible by a Wnt inhibitor.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

This review discusses the role of transient receptor potential channels in pathological scarification and suggests these channels as potential targets for its prevention and treatment, although it reports no new clinical findings.

In this study involving 15 women with alopecia, subcutaneous scalp injections of platelet-rich plasma every four weeks for three sessions led to increased hair and hair follicle density at 24 weeks, with common side effects being local swelling and pain.

PGD2 stops hair growth and is higher in bald men with AGA.

This study found that platelet-rich plasma significantly enhanced the viability, as well as the expression of alkaline phosphatase and versican, in human hair dermal papilla cells compared to controls.

This study found that a PGE2 matrix, when injected subcutaneously, increased the proportion of developing hair follicles and improved hair follicle stem cell markers in a mouse model of hair loss.

This study identified pantolactam based compounds as effective topical antagonists of the androgen receptor, reducing sebum components in a hamster model.

This study found that the catalytically inactive serine protease CAP1/Prss8 can still induce skin disorders in mice and is subject to inhibition by nexin-1, independent of its catalytic activity.

This review examines platelet-rich plasma for tissue repair and regeneration, reporting promising but inconclusive efficacy across applications; the authors stress the need for rigorous clinical trials.

This review evaluates the clinical efficacy of platelet-rich plasma therapy in dermatology, highlighting recent research findings and discussing its potential and limitations without reporting new clinical results.

This study found that, in male patients with patellar tendinopathy, bone marrow mesenchymal stromal cell treatment improved tendon regeneration, organization, strength, and pain relief more effectively than leukocyte-poor platelet-rich plasma over 12 months.

This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.

In this study, the researchers reported that NMMHC IIA dissociates from PAR1 and activates the CREB3/ARF4 pathway, worsening thrombin-induced blood-brain barrier damage, suggesting it as a potential therapeutic target for blood-brain barrier-related diseases.

This article discusses the affordability and safety of platelet-rich plasma gel production but presents no new research findings.

This case report describes how autologous platelet-rich plasma treatment led to complete healing of a chronic wound in a 72-year-old male patient after other standard treatments failed.

This review highlights that platelet-rich plasma and adipose-derived stem cell therapy may offer safe and promising improvements for managing symptoms of genital lichen sclerosus, with a potential synergistic benefit when combined.

In this study, researchers identified two novel peptidylarginine deiminases from treated rat keratinocytes, both showing enzyme activity with PAD‐R11 reflecting a characteristic of epidermal enzymes.

This review discusses the role of Prostaglandin D2 and its synthase in androgenetic alopecia but reports no new clinical findings, suggesting pathways for future therapeutic development.

This review discusses the roles of platelets in hemostasis and wound repair, the preparation methods for platelet concentrates, and their therapeutic applications in medicine and dentistry, reporting no new clinical results.

This study found that Placenderm®, a porcine placenta peptide, may promote hair follicle regeneration and enhance hair growth in mice by balancing growth-promoting and inhibitory factors.

This review highlights that injectable biostimulatory agents like poly-L-lactic acid, polycaprolactone, and calcium hydroxyapatite are effective in regenerative aesthetics by enhancing collagen production, stimulating adipogenesis, and improving dermal quality, although further research is needed to standardize protocols and confirm long-term safety and efficacy.

PRP treatment improved skin pigmentation and appearance in facial lichen planus pigmentosus.

This study identified a new dermoscopic feature, plexiform erythema, in lichen planopilaris lesions, suggesting it may indicate active disease and the potential need for more aggressive treatment.

This review discusses the use of platelet-rich plasma therapy in aesthetic anti-aging treatment, highlighting its reported safety and effectiveness in skin regeneration, but presents no original clinical results.

This review discusses the modern production methods, mechanisms of action, and various uses of platelet-rich plasma in medicine, highlighting promising applications but noting the need for more high-quality research.

In this study, the pi4kβ1β2 double mutant in Arabidopsis thaliana exhibited altered root growth, increased susceptibility to Blumeria graminis, and a potential correlation between PI4K activity and auxin response and immunity due to changes in vesicular trafficking and actin filaments.

This review highlights the current uses of platelet-rich plasma in plastic surgery and reports no new research findings.

LMWP-PDGFA shows promise for improving hair health and treating hair loss with fewer side effects.
