To address the need of alternatives to autologous vessels for small-calibre vascular applications (e.g. cardiac surgery), a bio-hybrid semi-degradable material composed of silk fibroin (SF) and polyurethane (Silkothane®) was herein used to fabricate very small-calibre grafts (Ø= 1.

Purpose Of Review: Mesenchymal stromal cells (MSC) have been proposed as a novel cell therapy for immune-mediated diseases, including solid organ transplantation. Here, we provide an overview of recent preclinical and clinical studies in solid organ transplantation using MSC immunomodulatory therapy.

Recent Findings: MSC have been tested successfully in models of corneal and lung transplantation, suggesting that either the programmed cell death protein 1/programmed death ligand 1 pathway or the generation of intermediary immune-regulatory monocyte-macrophage population are the main mechanisms of the protolerogenic effect of MSC.

Background: The rat orthotopic lung transplant model is not widely used yet because of the complexity of the procedure, in particular, venous anastomosis. Here, we performed a rat orthotopic lung transplantation using either the suture (ST) or cuff (CT) method for vein anastomosis.

Objectives: To compare the vein ST and CT techniques in terms of operative time, success, recipient survival, and early histological outcomes was the objective of this study.

Background: Mesenchymal stromal cells (MSCs) have protolerogenic effects in renal transplantation, but they induce long-term regulatory T cells (Treg)-dependent graft acceptance only when infused before transplantation. When given posttransplant, MSCs home to the graft where they promote engraftment syndrome and do not induce Treg. Unfortunately, pretransplant MSC administration is unfeasible in deceased-donor kidney transplantation.

We report here the long-term clinical and immunological results of four living-donor kidney transplant patients given autologous bone marrow-derived mesenchymal stromal cells (MSCs) as part of a phase 1 study focused on the safety and feasibility of this cell therapy. According to study protocols implemented over time, based on initial early safety findings, the patients were given MSC at day 7 posttransplant ( = 2) or at day -1 pretransplant ( = 2) and received induction therapy with basiliximab and low-dose rabbit anti-thymocyte globulin (RATG) or RATG alone, and were maintained on low-dose ciclosporin (CsA)/mycophenolate mofetil (MMF). All MSC-treated patients had stable graft function during the 5- to 7-year follow-up, without increased susceptibility to infections or neoplasm.
