Consumer Information on: XPS System with STEEN Solution Perfusate - H120003

The XVIVO Perfusion System (XPS) with STEEN Solution Perfusate preserves donated lungs that do not initially meet the standard criteria for lung transplantation but may be transplantable if there is more time to observe and evaluate the organ?s function.

Conclusions Fibroblasts play a critical role during periodontal wound healing. These cell populations are needed for the regeneration of a stable fibrillar connection between the tooth root, the gingiva, and the periodontal ligament. Importantly, regeneration of connective tissues involves different cellular activities driven by fibroblasts populations. These include the secretion of matrix molecules and the organization of these matrix components into functionally active fibers that finally restore the periodontium. Future studies should explore the cellular and molecular regulation of these cell populations and gain a m...

In this study, we show that PD-1 acts to inhibit the effector functions of virus-specific CD8 bTRM during MuPyV encephalitis. NanoString inflammatory gene expression analysis of brains of wild type (WT) and PD-L1−/− mice infected with MuPyV revealed that PD-1 signaling controls the inflammatory response during acute infection. In striking contrast, the absence of PD-1 signaling during persistent infection resulted in lower neuroinflammation than in WT mice. PD-1 was further found to affect the differentiation of virus-specific CD8 bTRM. Together, these findings reveal a complex, dynamic impact of PD-1 on neuroi...

In this study the effect of NMP perfusion fluid on survival, metabolism and function of thawed cryopreserved human (h)MSC and porcine (p)MSC in suspension conditions was studied. Suspension conditions reduced the viability of pMSC by 40% in both perfusion fluid and culture medium. Viability of hMSC was reduced by suspension conditions by 15% in perfusion fluid, whilst no differences were found in survival in culture medium. Under adherent conditions, survival of the cells was not affected by perfusion fluid. The perfusion fluid did not affect survival of fresh MSC in suspension compared to the control culture medium. The f...

Abstract PURPOSE OF REVIEW: The current review presents a concise update on published literature on donation after circulatory death (DCD) and lung transplantation (LTx). Worldwide an increasing need for lungs is evident, however the utilization rate of DCD lung donors is still considerably low. In this summary article, we reviewed both the experimental background and international clinical experience. RECENT FINDINGS: Our analysis confirmed satisfactory results for LTx from DCD donors, which equals the results from donation after brain death. Although most studies reported on short-term results, some confirm...

Lung transplantation is lifesaving for patients with end-stage lung diseases. However, a scarcity of donor lungs suitable for transplantation limits the number of procedures that can be performed. Furthermore, major obstacles to successful lung transplantation still exist; primary graft dysfunction (PGD), the leading cause of early morbidity and mortality post-lung transplant, develops in ~15–30% of recipients [1]. Normothermic ex vivo lung perfusion (EVLP) maintains donor lungs in a physiological state through perfusion and ventilation, so that the lungs can be assessed, treated and accepted for transplantation, the...

Ex vivo lung perfusion (EVLP) has been proposed as a platform for lung graft assessment and preservation. However, its proinflammatory milieu may be associated with deterioration in graft quality which may contribute to posttransplant graft dysfunction. Triptolide (TL), a diterpenoid triepoxide, has recently been shown to have a therapeutic potential in various disease states due to its anti-inflammatory properties. Based on this, we sought to assess the impact of TL on graft preservation during EVLP as well as associated posttransplant outcomes.

Ex vivo lung perfusion (EVLP) enables novel therapeutic approaches to repair damaged lungs for transplantation. We investigated the concept and feasibility of elective cell therapy for donor lungs. Dosing, efficacy and transgene expression kinetics of engineered mesenchymal stromal cell therapy were examined in pig EVLP and transplantation.
