BACKGROUND: The platelets used in oral, maxillofacial, and plastic surgery are generally grouped as concentrated platelet-rich plasma. The general principle of production consists of a centrifugation, making it possible to eliminate red blood cells, then acellular plasma, to preserve only the concentrated platelets. OBJECTIVE: The aim of the present study was that micro porous tricalcium phosphate (β-TCP) mixed with autologous platelet-derived growth factors could be an alternative to fat and hyaluronic acid which are widely used for oral and maxillofacial soft tissue augmentation...

Platelet-rich plasma (PRP) is a solution derived from whole blood that is enriched in the platelet fraction. Platelets serve as a reservoir of growth factors and cytokines. When platelets are activated in vivo, signaling molecules are released into the immediate microenvironment and activate receptors for various pathways. Historically, PRP has been applied to wound beds to promote healing of complex wounds. Over the last decade, it has served as a valuable therapeutic tool in various specialties such as maxillofacial surgery, plastic surgery, orthopedics and sports medicine...

BACKGROUND: Current options for in vivo regeneration of dermal tissue remain limited. The purpose of this study was to engineer a unique scaffold capable of recruiting dermal stem cells from adjacent tissue, thus circumventing the need to seed the scaffolds with stem cells before implantation, leading to skin regeneration. METHODS: A hydrogel scaffold was created through combination of type I collagen along with fractionated platelet-rich plasma. This was compared to a control hydrogel consisting of type I collagen and fetal bovine serum...

Treatment of lichen planopillaris (LPP) remains a significant challenge due to the irreversible damage inflicted on hair follicles combined with the low efficacy of existing treatments. We hypothesized that growth factors released by the use of platelet-rich plasma (PRP) may arrest the development of LPP. To test our hypothesis, we treated an LPP patient that has failed previous treatments with a new PRP regimen. Following PRP treatment and six months follow-up, the patient experienced complete regression of itching and hair shedding...

Androgenetic alopecia is the progressive miniaturization of the scalp's terminal follicles in aging men. Over 40% of Caucasian men develop hair loss by the age of 40. Despite its prevalence, there are only two FDA approved medications to treat the condition. Recognizing the unmet need, new medical, procedural, and surgical treatments are being adopted to combat progressive hair loss. This review examines emerging hair loss treatments including medical therapies that the target prostaglandins, low level light therapy, platelet rich plasma injections, and robotic hair transplantation...

Fractional lasers were first developed based on observations of lasers designed for hair transplantation. In 2007, ablative fractional laser resurfacing was introduced. The fractionation allowed deeper tissue penetration, leading to greater tissue contraction, collagen production and tissue remodeling. Since then, fractional erbium:YAG resurfacing lasers have also been introduced. These lasers have yielded excellent results in treating photoaging, acne scarring, and dyschromia. With the adjustment of microspot density, pulse duration, number of passes, and fluence, the surgeon can adjust the treatment effects...

Growing evidence has shown the promise of mesenchymal stromal cells (MSCs) for the treatment of cutaneous wound healing. We have previously demonstrated that MSCs seeded on an artificial dermal matrix, Integra (Integra Lifesciences Corp., Plainsboro, NJ) enriched with platelet-rich plasma (Ematrix) have enhanced proliferative potential in vitro as compared with those cultured on the scaffold alone. In this study, we extended the experimentation by evaluating the efficacy of the MSCs seeded scaffolds in the healing of skin wounds in an animal model in vivo...

To investigate the safety and clinical efficacy of AA-PRP injections for pattern hair loss. AA-PRP, prepared from a small volume of blood, was injected on half of the selected patients' scalps with pattern hair loss. The other half was treated with placebo. Three treatments were given for each patient, with intervals of 1 month. The endpoints were hair re-growth, hair dystrophy as measured by dermoscopy, burning or itching sensation, and cell proliferation as measured by Ki-67 evaluation. At the end of the 3 cycles of treatment, the patients presented clinical improvement in the mean number of hairs, with a mean increase of 18...

BACKGROUND: Pilonidal is a painful disease which occurs mainly in the sacrococcygeal area. In 1833 Herbert Mayo first reported a case of a young woman with a hair-containing sinus in the sacrococcygeal area. In 1880, Hodge suggested the term "pilonidal" from the Latin "pilus" for hair and "nidus" meaning nest. OBJECTIVES: Effect of using autologous platelet-rich plasma (PRP) on pain reduction in patients with pilonidal abscess, subjected to extensive surgical removal tissue, was investigated through a clinical trial...

Besides the presence of somatic stem cells in hair follicles and dermis, the epidermis also contains a subpopulation of stem cells, reflecting its high regenerative capacity. However, only limited information concerning epidermis-derived epithelial-like stem/progenitor cells (EpSCs) is available to date. Nonetheless, this stem cell type could prove itself useful in skin reconstitution after injury. After harvesting from equine epidermis, the purified cells were characterized as EpSCs by means of positive expression for CD29, CD44, CD49f, CD90, Casein Kinase 2β, p63, and Ki67, low expression for cytokeratin (CK)14 and negative expression for CD105, CK18, Wide CK, and Pan CK...
