[PMID: 38586873 PMCID: PMC10997806 DOI: 10.1016/j.reth.2024.03.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 03/06/2024] [Accepted: 03/15/2024] [Indexed: 04/09/2024] Open
Abstract
Platelet-rich plasma (PRP) has the capability of assisting in the recovery of damaged tissues by releasing a variety of biologically active factors to initiate a hemostatic cascade reaction and promote the synthesis of new connective tissue and revascularization. It is now widely used for tissue engineering repair. In addition, PRP has demonstrated nerve repair and pain relief, and has been studied and applied to the facial nerve, median nerve, sciatic nerve, and central nerve. These suggest that PRP injection therapy has a positive effect on nerve repair. This indicates that PRP has high clinical value and potential application in nerve repair. It is worthwhile for scientists and medical workers to further explore and study PRP to expand its application in nerve repair, and to provide a more reliable scientific basis for the opening of a new approach to nerve repair.

Abstract
Spinal diseases are commonly associated with pain and neurological symptoms, which negatively impact patients' quality of life. Platelet-rich plasma (PRP) is an autologous source of multiple growth factors and cytokines, with the potential to promote tissue regeneration. Recently, PRP has been widely used for the treatment of musculoskeletal diseases, including spinal diseases, in clinics. Given the increasing popularity of PRP therapy, this article examines the current literature for basic research and emerging clinical applications of this therapy for treating spinal diseases. First, we review in vitro and in vivo studies, evaluating the potential of PRP in repairing intervertebral disc degeneration, promoting bone union in spinal fusion surgeries, and aiding in neurological recovery from spinal cord injury. Second, we address the clinical applications of PRP in treating degenerative spinal disease, including its analgesic effect on low back pain and radicular pain, as well as accelerating bone union during spinal fusion surgery. Basic research demonstrates the promising regenerative potential of PRP, and clinical studies have reported on the safety and efficacy of PRP therapy for treating several spinal diseases. Nevertheless, further high-quality randomized controlled trials would be required to establish clinical evidence of PRP therapy.

A novel cell-free intrathecal approach with PRP for the treatment of spinal cord multiple sclerosis in cats. Inflamm Regen 2022; 42:45. [PMID: 36229845 PMCID: PMC9563497 DOI: 10.1186/s41232-022-00230-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Accepted: 08/28/2022] [Indexed: 11/24/2022] Open
Abstract
Background Multiple sclerosis (MS) is a progressive autoimmune demyelinating disease of the central nervous system. To date, there is no effective therapy for it. Our study aimed to determine the potential role of platelet-rich plasma (PRP) in the treatment of MS in cats. Methods The current study was conducted on 15 adult Persian cats that were divided into three groups: control negative, control positive (ethidium bromide (EB)-treated group), and PRP co-treated group (EB-treated group intrathecally injected with PRP on day 14 post-spinal cord injury). PRP was obtained by centrifuging blood on anticoagulant citrate dextrose and activating it with red and green laser diodes. The Basso–Beattie–Bresnahan (BBB) scores were used to assess the motor function recovery on days 1, 3, 7, 14, 20, and 28 following 14 days from EB injection. Moreover, magnetic resonance imaging (MRI) analysis, histopathological investigations, transmission electron microscopy (TEM) studies, and immunohistochemical analysis were conducted, and the gene expressions of nerve growth factors (NGFs), brain-derived neurotrophic factors (BDNF), and stromal cell-derived factors (SDF) were evaluated. Results Our results indicated that PRP had a significant ameliorative effect on the motor function of the hindlimbs as early as day 20 and so on. MRI revealed that the size and intensity of the lesion were significantly reduced in the PRP co-treated group. The histopathological and TEM investigations demonstrated that the PRP co-treated group had a significant improvement in the structure and organization of the white matter, as well as a high remyelination capacity. Furthermore, a significant increase in myelin basic protein and Olig2 immunoreactivity as well as a reduction in Bax and glial fibrillar acidic protein immune markers was observed. NGFs were found to be upregulated by gene expression. Conclusion As a result, we concluded that the intrathecal injection of PRP was an effective, safe, and promising method for the treatment of MS.

Abstract
Trichinellosis is a food-borne parasitic infection causing muscle damage. This study aimed to detect the potential therapeutic effect of platelet-rich plasma (PRP) alone or in combination with albendazole (ALB) on the muscular phase of experimental Trichinella infection in rats. The study was conducted on 70 rats divided into four main groups: healthy non-infected non-treated rats, non-infected rats treated with PRP, infected untreated rats (seven rats in each group), and an infected group of 49 rats. The infected group was further subdivided based on the drug therapy received. The effects of drug therapy were evaluated using parasitological and histopathological analyses. The percent reduction in the number of Trichinella spiralis larvae per gram of muscle in the PRP-treated groups (one, two, and three doses) was 43.1%, 78.8%, and 86.1%, respectively. Groups treated with combined therapy of ALB & PRP (one, two, and three doses) showed overall reduction percentages of 87.7%, 90.9% and 95.2%, respectively. In contrast, the ALB-treated group showed a 69.4% reduction. All results of the abovementioned groups were statistically significant compared to the control-infected non-treated group. The findings of the histopathological analysis were consistent with the parasitological results. Groups receiving combined therapy showed the most significant improvement in terms of the degree of inflammation and fibrosis. It can be concluded that PRP has a modulatory effect on the pathology caused by T. spiralis larvae in the muscular phase of trichinellosis. To our knowledge, this is the first study to investigate the effect of PRP on the muscular phase of T. spiralis infection. PRP has a modulatory effect on the pathology caused by T. spiralis larvae on the muscular phase of trichinellosis. Two and three doses of PRP therapy showed a therapeutic effect in the muscular phase of trichinellosis. Albendazole treatment combined with PRP is a promising treatment option. A potential role of platelets in controlling Trichinella infections is identified.

Physiol Behav 2022; 252:113840. [PMID: 35525286 DOI: 10.1016/j.physbeh.2022.113840] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 05/01/2022] [Accepted: 05/02/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND There are complex mechanisms for reducing intrinsic repairability and neuronal regeneration following spinal cord injury (SCI). Platelet-rich plasma (PRP) is a rich source of growth factors and has been used to motivate the regeneration of peripheral nerves in neurodegenerative disorders. However, only a few studies have shown the effects of PRP on the SCI models. METHODS We investigated whether PRP derived from human umbilical cord blood (HUCB-PRP) could recover motor function in animals with spinal cord injury. Sixty adult male Wistar rats were randomly divided into 6 groups (n=60) as control, sham (laminectomy without induction of spinal cord injury), SCI, vehicle (SCI+ Platelet-Poor Plasma), PRP2day (SCI+PRP injection 2 days after SCI), and PRP14day (SCI+PRP injection 14 days after SCI). SCI was performed at the T12-T13 level. BBB test was carried out weekly after injury for six weeks. Caspase3 expression was determined using the Immunohistochemistry technique. The expression of GSK3β, CSF-tau, and MAG was determined using the Western blot technique. Data were analyzed by PRISM & SPSS software. RESULTS HUCB-PRP treated animals showed a higher locomotor function recovery than those in the SCI group (p<0.0001). The level of caspase3, GSK3β and CSF- Tau reduced and the MAG level in the spinal cord increased by the injection of HUCB-PRP in SCI animals. CONCLUSION Injection of HUCB-PRP enhanced hind limb locomotor performance by modulation of caspase3, GSK3β, CSF-tau, and MAG expression. Using HUCB-PRP could be a new therapeutic option for recovering motor function and axonal regeneration after SCI.

Abstract
The present study attempted to elucidate whether intravesical instillation of platelet-rich plasma (PRP) could decrease bladder inflammation and ameliorate bladder hyperactivity in ketamine ulcerative cystitis (KIC) rat model. Female Sprague Dawley (S-D) rats were randomly divided into control group, ketamine-treated group, ketamine with PRP treated group, and ketamine with platelet-poor plasma (PPP) treated group. Cystometry and micturition frequency/volume studies were performed to investigate bladder function. The morphological change of bladder was investigated by Mason’s trichrome staining. Western blotting analysis were carried out to examine the protein expressions of inflammation, urothelial differentiation, proliferation, urothelial barrier function, angiogenesis and neurogenesis related proteins. The results revealed that treatment with ketamine significantly deteriorated bladder capacity, decreased voiding function and enhanced bladder overactivity. These pathological damage and interstitial fibrosis may via NF-κB/COX-2 signaling pathways and muscarinic receptor overexpression. PRP treatment decreased inflammatory fibrotic biosynthesis, attenuated oxidative stress, promoted urothelial cell regeneration, and enhanced angiogenesis and neurogenesis, thereafter recovered bladder dysfunction and ameliorate the bladder hyperactivity in KIC rat model. These findings suggested that the PRP therapy may offer new treatment options for those clinical KIC patients.

Abstract
Administration of platelet rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) has shown some promise in the treatment of neurological conditions; however, there is limited information on combined administration. As such, the purpose of this study was to assess safety and functional outcomes for patients administered combined autologous PRP and BMAC for spinal cord injury (SCI). This retrospective case series included seven patients who received combined treatment of autologous PRP and BMAC via intravenous and intrathecal administration as salvage therapy for SCI. Patients were reviewed for adverse reactions and clinical outcomes using the Oswestry Disability Index (ODI) for up to 1 year, as permitted by availability of follow-up data. Injury levels ranged from C3 through T11, and elapsed time between injury and salvage therapy ranged from 2.4 months to 6.2 years. Post-procedure complications were mild and rare, consisting only of self-limited headache and subjective memory impairment in one patient. Four patients experienced severe disability prior to PRP combined with BMAC injection, as evidenced by high (> 48/100) Oswestry Disability Index scores. Longitudinal Oswestry Disability Index scores for two patients with incomplete SCI at C6 and C7, both of whom had cervical spine injuries, demonstrated a decrease of 28–40% following salvage therapy, representing an improvement from severe to minimal disability. In conclusion, intrathecal/intravenous co-administration of PRP and BMAC resulted in no significant complications and may have had some clinical benefits. Larger clinical studies are needed to further test this method of treatment for patients with SCI who otherwise have limited meaningful treatment options. This study was reviewed and approved by the OhioHealth Institutional Review Board (IRB No. 1204946) on May 16, 2018.

Abstract
Spinal cord injury (SCI) as a crippling disability causes tissue degeneration via neuron loss and fiber disruption. Some researchers have tried to reverse or minimize these changes. Platelet-rich plasma (PRP) is a biological product derived from peripheral blood containing a variety of growth factors. PRP has been extensively used in regenerative medicine. On the other hand, via secreting neuroprotective growth factors, mesenchymal stem cells (MSCs) have shown a promising potential in repairing central nervous system deficits. This study investigated the therapeutic effect of the combined use of MSCs and PRP in a rat model of SCI. We used real time-PCR method for evaluation of Bcl-2, Bax and caspase 3 expressions, TUNEL test for apoptotic cell death assessment, and neurofilament NF200 immunohistochemistry for examination of axonal regeneration. The results showed that co-treatment with MSCs and PRP efficiently alleviated the evaluated categories. Significant differences were observed in expression of Bcl-2 and caspase3, but not Bax, apoptotic index and the number of NF200 positive axons (for all P ≤ 0.01) between co-treatment animals compared with those treated with only MSCs or PRP. In conclusion, this study showed that combination of MSCs and PRP synergistically promotes their therapeutic effects in the SCI.

Abstract
BACKGROUND Neuropathic pain following injury or dysfunction of the peripheral or CNS is one of the most important medical challenges to treat. Humane platelet-rich plasma (HPRP), which is a rich source of growth factors, may be able to treat and reduce pain caused by spinal cord injury (SCI). In this study, the effect of HPRP on neuropathic pain caused by SCI was investigated. METHODS Sixty adult male Wistar rats were randomly divided into 6 groups: control, sham, SCI, vehicle (SCI+platelet-poor plasma), SCI+ PRP2day (injection 48 hrs after SCI) and SCI+PRP14day (injection 14 days after SCI). SCI was induced at the T12-T13 level. Behavioral tests were conducted weekly after injury for six weeks. Allodynia and hyperalgesia were assessed using acetone drops, plantar test and von Frey filament. Cavity size and the number of fibroblasts were determined by H&E stain, and the expression of mTOR, p-mTOR, P2×3R and P2Y4R were determined using the western blot technique. Data were analyzed using PRISM & SPSS software. RESULTS PRP injection showed a higher pain threshold in mechanical allodynia (p<0.0001), cold allodynia (p<0.0001) and thermal hyperalgesia (p<0.0001) than those in the spinal. Animals treated with PRP also reduced cavity size, fibroblast number, p-mTOR/mTOR ratio, and P2×3R expression, and increased P2Y4R expression. The difference between the two groups was not statistically significant. CONCLUSIONS The results showed that PRP reduced SCI-induced allodynia and hyperalgesia by regulating ATP signaling. Using HPRP can open a new window in the treatment of pain caused by damage to the nervous system.

Abstract
Regenerative pain medicine, which seeks to harness the body's own reparative capacity, is rapidly emerging as a field within pain medicine and orthopedics. It is increasingly appreciated that common analgesic mechanisms for these treatments depend on neuroimmune modulation. In this Review, we discuss recent progress in mechanistic understanding of nociceptive sensitization in chronic pain with a focus on neuroimmune modulation. We also examine the spectrum of regenerative outcomes, including preclinical and clinical outcomes. We further distinguish the analgesic mechanisms of regenerative therapies from those of cellular replacement, creating a conceptual and mechanistic framework to evaluate future research on regenerative medicine.

To evaluate the effects of platelet-rich plasma (PRP) on promoting neural repair after facial nerve compression in rats and the mechanism by which this occurs. Methods: Adult Wistar rats (n=100) were divided into 3 groups: healthy controls, surgery-only, and surgery+PRP groups. The rats underwent nerve crush injury to establish a facial palsy model. The blood from the rats was used to prepare the PRP for application to the injury site. The evaluation methods included vibrissae movement, eyelid closure, and electrophysiology. Electron microscopy, immunohistochemistry, and real-time polymerase chain reaction (PCR) were used to detect nutrient factor expression in the brain and nerve sections. This study was conducted in Shandong Provincial ENT Hospital Affiliated to Shandong University, Shandong, China between January and November 2018. Results: Platelet-rich plasma promotes the recovery of vibrissae movement, eyelid closure, and electrophysiological function in a rat model of nerve crush injury. Hematoxylin and eosin staining, toluidine blue staining, and electron microscopy showed significant recovery of Schwann cells and axons in the PRP group. Polymerase chain reaction results showed that PRP releases growth factors, which include nerve growth factor and brain-derived neurotrophic factor. Immunohistochemistry also demonstrated higher levels of S-100 protein expression in the PRP group compared to the other groups. Conclusions: Platelet-rich plasma releases nutrient factors in the brainstem, and the use of PRP can promote injury recovery.

Abstract
Background/Aims Platelet-rich plasma (PRP) has been used for wound healing in various medical fields. The aim of this study was to evaluate the clinical efficacy and safety of local PRP injections after endoscopic submucosal dissection (ESD).
Methods Patients were non-randomly divided into the following two groups: (1) control group in which patients were administered only an intravenous proton pump inhibitor (PPI), and (2) a study group in which patients were administered an intravenous PPI and a topical PRP injection. We assessed the reduction in the ulcer area and stage of the ulcer after the procedure (24 hours, 48 hours, and 28 days after endoscopic surgery).
Results We enrolled 7 study and 7 control patients. In the study group, the rate of ulcer reduction was 59% compared to 52% in the control group (p=0.372), 28 days after ESD. There were 5 patients in the S stage and 2 patients in the H stage in the study group compared to no patient in the S stage and 7 patients in the H stage in the control group (p=0.05), 28 days after ESD. There were no serious complications in either group.
Conclusions The local injection of PRP is a safe and effective procedure for ulcer healing after ESD.

Abstract
The overall increase of chronic degenerative diseases associated with ageing makes wound care a tremendous socioeconomic burden. Thus, there is a growing need to develop novel wound healing therapies to improve cutaneous wound healing. The use of regenerative therapies is becoming increasingly popular due to the low-invasive procedures needed to apply them. Platelet-rich plasma (PRP) is gaining interest due to its potential to stimulate and accelerate the wound healing process. The cytokines and growth factors forming PRP play a crucial role in the healing process. This article reviews the emerging field of skin wound regenerative therapies with particular emphasis on PRP and the role of growth factors in the wound healing process.

Abstract
Purpose: To evaluated the tubulization technique with standard and inside-out vein, filled or not with platelet-rich plasma (PRP), in sciatic nerve repair. Methods: Seventy male Wistar rats were randomly divided into five groups: IOVNF (Inside-Out Vein with No Filling); IOVPRP (Inside-Out Vein filled with PRP); SVNF (Standard Vein with No Filling); SVPRP (Standard Vein filled with PRP); Sham (Control). The left external jugular vein was used as graft in a 10 mm nervous gap. Results: In the morphological analysis of all groups, myelinated nerve fibers with evident myelin sheath, neoformation of the epineurium and perineurium, organization of intraneural fascicles and blood vessels were observed. In the morphometry of the distal stump fibers, SVPRP group had the highest means regarding fiber diameter (3.63±0.42 μm), axon diameter (2.37±0.31 μm) and myelin sheath area (11.70±0.84 μm2). IOVPRP group had the highest means regarding axon area (4.39±1.16 μm2) and myelin sheath thickness (0.80±0.19 μm). As for values of the fiber area, IOVNF group shows highest means (15.54±0.67 μm2), but are still lower than the values of the Sham group. Conclusion: The graft filled with platelet-rich plasma, with use standard (SVPRP) or inside-out vein (IOVPRP), promoted the improvement in axonal regeneration on sciatic nerve injury.
