The previous study on the injection of SVFs in combination with PRP showed positive effect on the healing of deep dermal burns. We now seek to understand the effect on full thickness burns, as assessed by changes in serum FGF2, IGF1, epithelialization, and fibroblast count. Forty-eight Wistar rats were randomly divided into four groups: (1) rats with full thickness burns given a local injection of combined SVFs and PRP; (2) rats with burns given topical Vaseline; (3) rats with burns given a local injection of placebo; and (4) rats without burns...

Our previous study on how the combination of stromal vascular fraction cells (SVFs) and platelet-rich plasma (PRP) affect deep dermal burn healing showed promising results. In this study, we assessed the effect on full-thickness burns by evaluating FGF7 serum level and capillary count. Forty-eight Wistar rats were divided into four major groups: (1) locally injected with combined SVFs and PRP; (2) topically applied Vaseline; (3) locally injected with placebo; (4) and rats without burns. These groups were divided further into smaller groups based on the day of euthanasia (8th hour, 4th day, 7th day, 14th day, and 21st day)...

The combination of platelet-rich plasma (PRP) and stromal vascular fraction cells (SVFs) was beneficial in accelerating wound healing. This study aims to assess the effect of this combination in balancing the inflammatory process to accelerate burn healing. Thirty eligible Wistar rats were used in this study to establish a deep dermal degree burn wound model. They were randomly divided into four groups: locally injected with the combination of SVFs and PRP (n=9), vaseline (n=9), placebo (n=9), and healthy Wistar rats group (n=3), as treatment group, positive control group, negative control group and healthy control group, respectively...

Bone Marrow Stimulation of osteochondral lesions of the talus has been shown to be a successful way to treat cartilage injuries. Newer data suggest that Bone Marrow Stimulation is best reserved for osteochondral lesions of the talus Sizes Less Than 107.4 mm2 in area. Additionally, newer smaller and deeper techniques to perform bone marrow stimulation have resulted in less subchondral bone damage, less cancellous compaction, and superior bone marrow access with multiple trabecular access channels. Biologic adjuvants such as platelet-rich plasma (PRP), hyaluronic acid (HA), and bone marrow aspirate concentrate (BMAC) may lead to better functional outcomes when used concomitant to bone marrow stimulation...

Biological agents like growth factors (ie, platelet rich plasma) and mesenchymal stem cells are rising in popularity among orthopedics. Orthobiologics therapy aims to fill the gap between conventional conservative therapies like hyaluronic acid and surgery, especially for cartilage disease. Ankle cartilage defects are very symptomatic and could lead to a severe decrease of quality of life in patients, because of pain, swelling, and inability to walk without pain. In this scenario, this paper aims to systematically review the current literature available about biological therapies for ankle cartilage...

Dermal papilla cell (DPC) belongs to a specialized mesenchymal stem cell for hair follicle regeneration. Maintaining the ability of DPCs to stimulate hair in vitro culture is important for hair follicle morphogenesis and regeneration. As the third generation of platelet concentrate, injectable platelet-rich fibrin (i-PRF) is a novel biomaterial containing many growth factors and showing promising effects on tissue reconstruction. We aimed to explore the influences of i-PRF on the proliferative, migratory, as well as trichogenic ability of DPCs and compared the effects of i-PRF and platelet-rich plasma (PRP), the first generation of platelet concentrate...

Platelet-rich fibrin (PRF) is a widely used autologous blood concentrate in regenerative medicine. This study aimed to characterize the cellular composition and distribution of different PRF matrices generated by high (710 g) and low (44 g) relative centrifugal forces (RCFs) and to analyze their bioactivity on human primary osteoblasts (pOBs). PRF was separated into upper layer (UL) and buffy coat (BC) fractions, and their cellular contents were assessed using histological and immunohistochemical staining. The release of platelet-derived growth factor (PDGF) and transforming growth factor (TGF-β) was quantified using an ELISA...

Chronic odontogenic maxillary sinusitis (COMS), a prolonged inflammation of the maxillary sinus lasting over 12 weeks, is often a result of periapical lesions, marginal periodontitis, and complications like oro-antral communication (OAC) and fistula (OAF). OAC, commonly emerging post-teeth extraction in the lateral maxilla, lacks documented treatments using advanced platelet-rich fibrin (A-PRF). This study evaluates A-PRF's efficacy in treating COMS and immediately sealing extensive OAC. A case of a 28-year-old male with COMS linked to a periapical lesion and supernumerary molars is presented...

Individual differences in the response to platelet-rich plasma (PRP) therapy can be observed among patients. The genetic background may be the cause of this variability. The current study focused on the impact of genetic variants on the effectiveness of PRP. The aim of the present study was to analyze the impact of single nucleotide polymorphisms (SNP) of the platelet-derived growth factor receptor alpha ( PDGFRA ) gene on the effectiveness of treating lateral elbow tendinopathy (LET) with PRP. The treatment's efficacy was analyzed over time (2, 4, 8, 12, 24, 52 and 104 weeks after the PRP injection) on 107 patients using patient-reported outcome measures (PROM) and achievement of a minimal clinically important difference (MCID)...
