Studies on patient-specific human-induced pluripotent stem cells (hiPSCs) as well as a series of autologous growth factors presumably will reveal their many benefits for cell base replacement therapy in type 1 diabetes mellitus (TIDM) patients in the future. For this purpose, we established a multistep protocol by adding platelet-rich plasma (PRP) that induce the hiPSCs into insulin-producing cells (IPCs). We present here a differentiation protocol consisting of five stages in two groups including protocol with PRP and without PRP...

Delayed fracture healing and nonunion occurs in up to 5-10% of all fractures, and can present a challenging clinical scenario for the treating physician. Methods for the enhancement of skeletal repair may benefit patients that are at risk of, or have experienced, delayed healing or nonunion. These methods can be categorized into either physical stimulation therapies or biological therapies. Physical stimulation therapies include electrical stimulation, low-intensity pulsed ultrasonography, or extracorporeal shock wave therapy...

Apical revascularization (AR) and platelet-rich plasma have been used to restore dental pulp vitality in infected immature permanent teeth. Two regenerative therapies are cell transplantation and cell homing. This article updates and benchmarks these therapies with cell homing. A case report concluded that AR increased root length; however, quantitative and statistical assessments disproved this. Regenerative endodontic therapies require prospective clinical trials demonstrating safety and efficacy. These therapies are intrinsically susceptible to procedural and patient variations...

Equid herpes virus type-1 (EHV-1) is a major pathogen of horses, causing abortion storms and outbreaks of herpes virus myeloencephalopathy. These clinical syndromes are partly attributed to ischemic injury from thrombosis in placental and spinal vessels. The mechanism of thrombosis in affected horses is unknown. We have previously shown that EHV-1 activates platelets through virus-associated tissue factor-initiated thrombin generation. Activated platelets participate in thrombus formation by providing a surface to localize coagulation factor complexes that amplify and propagate thrombin generation...

BACKGROUND/AIM: Significant biological differences in platelet-rich plasma (PRP) preparations have been highlighted and could explain the large variability in the clinical benefit of PRP reported in the literature. The scientific community now recommends the use of classification for PRP injection; however, these classifications are focused on platelet and leucocyte concentrations. This presents the disadvantages of (1) not taking into account the final volume of the preparation; (2) omitting the presence of red blood cells in PRP and (3) not assessing the efficiency of production...

Urethral stricture is one of the most bothersome urologic disease among urologists and has a substantial impact on quality of life and healthcare costs. Although it can be cured with internal urethrotomy easily, post-surgery stricture recurrence is challenging. Several adjuvant therapies have been used in conjunction with internal urethrotomy but none of them are used routinely because the pathophysiology of the disease is still obscure. Fibrosis is the most accused hypothesis for the action. Platelet-rich plasma (PRP) is an autologous blood product containing a high concentration of platelets that is being used for a very wide range of clinical healing applications...

Root canal therapy has enabled us to save numerous teeth over the years. The most desired outcome of endodontic treatment would be when diseased or nonvital pulp is replaced with healthy pulp tissue that would revitalize the teeth through regenerative endodontics. 'A search was conducted using the Pubmed and MEDLINE databases for articles with the criteria 'Platelet rich plasma', 'Platelet rich fibrin', 'Stem cells', 'Natural and artificial scaffolds' from 1982-2015'. Tissues are organized as three-dimensional structures, and appropriate scaffolding is necessary to provide a spatially correct position of cell location and regulate differentiation, proliferation, or metabolism of the stem cells...

In mammals, axons of injured peripheral nerves (PNI) can and do regenerate, but often the functional recovery is incomplete or suboptimal. In recent years, in vivo tissue engineering approaches through molecular intervention and scaffolding are offering promising outcomes. Evidence is accumulating in both preclinical and clinical settings indicating that platelet rich plasma (PRP) and fibrin scaffolds obtained from this technology hold an important adjuvant therapeutic potential. Areas covered: This review addresses current molecular and cellular data in intrinsic nerve repair processes and describes different strategies to harness and enhance these processes by using biochemical and biomechanical cues...

Bone defects remain a challenge for patients and orthopaedic surgeons. Autologous transfer of cancellous bone grafts remains the standard of care. However, in recent years various osteoinductive substitute materials, such as platelet rich plasma (PRP) and hyperbaric oxygen therapy (HBO) have been shown to improve bone healing. This study evaluates the effects of a combined application of PRP and HBO with autologous bone grafting in an animal model. In 48 New Zealand White rabbits bone defects at the radius were filled with autologous bone harvested at the iliac crest...

Alopecia areata (AA) is non-scarring hair loss resulting from an autoimmune disorder. Severity varies from patchy hair loss that often spontaneously resolves to severe and chronic cases that can progress to total loss of scalp and body hair. Many treatments are available; however, the efficacy of these treatments has not been confirmed, especially in severe cases, and relapse rates are high. First-line treatment often includes corticosteroids such as intralesional or topical steroids for mild cases and systemic steroids or topical immunotherapy with diphenylcyclopropenone or squaric acid dibutylester in severe cases...
