Purpose: Autologous platelet rich plasma (PRP) is used increasingly in a variety of settings. PRP injections have been used for decades to improve angiogenesis and wound healing. They have also been offered commercially in urology with little to no data on safety or efficacy. PRP could theoretically improve multiple urologic conditions, such as erectile dysfunction (ED), Peyronie's disease (PD), and stress urinary incontinence (SUI). A concern with PRP, however, is early washout, a situation potentially avoided by conversion to platelet rich fibrin matrix (PRFM)...

The objective of the study was to review current literature to determine whether the topical application of platelet-rich plasma (PRP) promotes healing in experimentally-induced full-thickness skin wounds in animals. The hypothesis was that the adjunct of PRP has a positive effect on wound healing. An electronic search was carried out on the following databases: Web of Science, Cochrane Library, PubMed, Research Gate, Cochrane Wounds Group, Veterinary Information Network. No publication date nor language restrictions were applied...

The poor healing potential of tendons is still a clinical problem, and the use of Platelet Rich Plasma (PRP) was hypothesized to stimulate healing. As the efficacy of PRPs remains unproven, platelet lysate (PL) could be an alternative with its main advantages of storage and characterization before use. Five different blood products were prepared from 16 male donors: human serum, two PRPs (Arthrex, (PRP-ACP); RegenLab (PRP-BCT)), platelet concentrate (apheresis, PC), and PL (freezing-thawing destruction of PC)...

AIM OF THE STUDY: The aim of the study was to evaluate the effect of leukocyte- and platelet-rich plasma (L-PRP) treatment on a noncomplicated would healing after surgical skin incision in an experimental animal model. MATERIALS AND METHODS: The blood from 64 male Wistar rats was used to prepare L-PRP before a transverse dorsal incision was made and consecutively closed. At the same time after the surgery was completed, autologous L-PRP in the rats from the L-PRP group (n = 32) and NaCl in the control group (n = 32) were injected subcutaneously into the wound...

BACKGROUND: Striae distensae are dermal scars with a linear atrophic depression. The exact origin of striae distensae remains unrevealed, but low expression of collagen and fibronectin genes in the affected tissue was found. Several treatment modalities have been proposed, yet no consistent modality is available. AIM OF THE WORK: To evaluate and compare the efficacy and safety of carboxytherapy vs platelet-rich plasma (PRP) in treatment of stretch marks. PATIENTS AND METHODS: This study included 20 patients with striae alba...

BACKGROUND: Adipose-derived stem cell (ADSCs)-assisted and platelet-rich plasma (PRP)-assisted lipofilling aim to enhance angiogenesis and cell proliferation and are promising techniques for lipofilling. This study aimed to compare the outcomes of ADSCs-assisted and PRP-assisted lipofilling. METHODS: Adipose tissue and human venous blood were obtained from women with early breast cancer. Human ADSCs were isolated and amplified in vitro. PRP was extracted through double centrifugation...

PRPs can be used in the management of tendinopathy if we improve our understanding of pathophysiology and achieve to integrate molecular knowledge about PRP participation in healing mechanisms. Areas covered: We provide new insights into the pathophysiology of tendinopathy, PRP therapies, and the potential links between both. We discuss the place of PRP in promoting tendon repair within what is currently understood of the role of PRP molecules in promoting tendon regeneration. We also highlight the many opportunities for further exploration and identification of strategically designed treatments providing meaningful clinical benefit...

Background: Due to the known disadvantages of autologous bone grafting, tissue engineering approaches have become an attractive method for ridge augmentation in dentistry. To the best of our knowledge, this is the first study conducted to evaluate the potential therapeutic capacity of PRP-assisted hADSCs seeded on HA/TCP granules on regenerative healing response of canine alveolar surgical bone defects. This could offer a great advantage to alternative approaches of bone tissue healing-induced therapies at clinically chair-side procedures...

BACKGROUND: Management of periorbital hyperpigmentation (POH) is still a therapeutic challenge. Although different therapeutic modalities are available, the outcomes of most of them are unsatisfactory. OBJECTIVES: To investigate and compare the efficacy and safety of two new modalities in the treatment of POH; the platelet rich plasma (PRP) and the carboxytherapy. SUBJECTS AND METHODS: The study included 30 patients with POH. Every patient was subjected to seven intradermal injections of PRP on the left periorbital area with 2 week intervals between sessions and carboxytherapy on the right area with 1 week interval apart...

This study aimed to investigate the effect of PRP on Wnt/β-catenin signaling in rabbit chondrocytes. METHODS: Using 3-month-old New Zealand white rabbits, PRP was prepared from venous blood, and chondrocytes were cultured from knee joint cartilage and identified by staining for type II collagen and proteoglycan. The effects of PRP on chondrocyte viability were measured...

MATERIALS AND METHODS: A total of 20 healthy Wistar albino female rats were divided into two groups. In Group 1, the left tympanic membranes were perforated and grafted with a fat graft that was harvested from the inguinal region.

Objective: It has been proved that platelet-rich plasma (PRP) can promote wound healing. In this way, PRP can be advantageous in periodontal plastic surgeries, free gingival graft (FGG) being one such surgery. Materials and Methods: In this randomized split-mouth controlled trial, 10 patients who needed bilateral FGG were selected, and two donor sites were randomly assigned to experience either natural healing or healing-assisted with PRP. The outcome was assessed based on the comparison of the extent of wound closure, Manchester scale, Landry healing scale, visual analog scale, and tissue thickness between the study groups at different time intervals...

METHODS: A total of 16 male mice were included. When selecting the mice, the food-finding test (FFT) was used to make sure that the animals could smell, and anosmia was induced by administration of intraperitoneal 3-methylindole. The mice were randomly divided into two groups of eight (groups A and B)...

The aim of the present study was to evaluate the effect of injectable platelet-rich fibrin (i-PRF) on cultivated chondrocytes and osteochondral regeneration in critical-sized osteochondral defect of the rabbit's knee in comparison to autologous platelet-rich plasma (PRP). Chondrocytes were first investigated for their ability to proliferate and differentiate in response to PRP and i-PRF. Thereafter, full-thickness critical-sized osteochondral defects 5 mm in diameter and 5 mm in depth were created in the knee joint of 12 adult female New Zealand White rabbits...
