Vascular diseases are increasing health problems affecting >25 million individuals in westernized societies. Such patients could benefit from transplantation of tissue-engineered vascular grafts using autologous cells. One challenge that has limited this development is the need for cell isolation, and risks associated with ex vivo expanded stem cells. Here we demonstrate a novel approach to generate transplantable vascular grafts using decellularized allogeneic vascular scaffolds, repopulated with peripheral whole blood (PWB) in vitro in a bioreactor. Circulating, VEGFR-2+/CD45+ and a smaller fraction of VEGFR-2+/CD14+ cells contributed to repopulation of the graft. SEM micrographs showed flat cells on the luminal surface of the grafts consistent with endothelial cells. For clinical validation, two autologous PWBtissue-engineered vein conduits were prepared and successfully used for bypass procedures in two pediatric patients. These results provide a proof of principle for the generation of transplantable vascular grafts using a simple autologous blood sample, making it clinically feasible globally. (C) 2014 The Authors.

Combined Use of Detergents and Ultrasonication for Generation of an Acellular Pig Larynx

Nikhil B. Nayakawde, Ketaki Methe, Goditha U. Premaratne, Debashish Banerjee, Michael Olausson

Summary: The larynx is a complex organ consisting of various muscles, cartilages, mucosal membrane, and nerves, with larynx cancer being the most common type of head and neck cancer. Treatment options are limited for patients undergoing total or partial laryngectomy, but tissue-engineered organs have shown promise as an alternative. A novel decellularization method involving perfusion-agitation with detergents and ultrasonication was used to construct a pig larynx scaffold with preserved ECM proteins and angiogenic growth factors.

Live Birth Following Uterine Transplantation From a Nulliparous Deceased Donor

Jiri Fronek, Libor Janousek, Jakub Kristek, Jaroslav Chlupac, Marek Pluta, Robert Novotny, Jana Maluskova, Michael Olausson

Summary: This study reported the first live birth after a deceased donor uterus transplant in Europe, demonstrating that nulliparous uteri may be a suitable source of uterine grafts for transplantation. Stenting appears to be a feasible treatment for vaginal anastomotic stenosis.

Luminal polyethylene glycol solution delays the onset of preservation injury in the human intestine

John M. Softeland, Jasmine Bagge, Arvind M. Padma, Anna Casselbrant, Changlian Zhu, Yafeng Wang, Mats Hellstrom, Michael Olausson, Mihai Oltean

Summary: The study validated the efficacy of luminal polyethylene glycol (PEG) in reducing damage to the intestinal epithelium during cold storage (CS) of intestinal grafts. Luminal PEG treatment significantly lowered mucosal injury, redistributed tight junction proteins earlier, and showed an emerging unfolding protein response after 24 hours of CS. Increased caspase activity was found in the control group, suggesting the potential of luminal PEG as a safe and effective intervention.

Human Uterus Transplantation from Living and Deceased Donors: The Interim Results of the First 10 Cases of the Czech Trial

Jiri Fronek, Jakub Kristek, Jaroslav Chlupac, Libor Janousek, Michael Olausson

Summary: The results of the study demonstrate a high mid-term viability in uterus transplantation, with differences in outcomes between live donors and deceased donors. Live donor UTx has a higher success rate, and nulliparous donors should be considered for donation.

A pilot retrospective CT angio study of the internal pudendal arteries in male bodies, for the purpose of penis transplantation to trans men

Gennaro Selvaggi, Kristiina Manner, Augustinas Sakinis, Michael Olausson

Summary: Literature reports successful cases of penile transplantation for cis men, with no attempts for trans men. Modern surgical techniques for penis reconstruction may have limitations, making penis transplantation a potential alternative. The study confirmed the feasibility of using the internal pudendal artery for arterial anastomosis in transplantation procedures based on measurements of diameter and length.

Characterization of Decellularized Implants for Extracellular Matrix Integrity and Immune Response Elicitation

Summary: Biological scaffolds prepared by decellularization and implanted using different routes were studied to understand the differential immune responses elicited. The use of sensitive protein and genomic tools provided valuable insights into the changes associated with chemical decellularization and postimplantation. This study contributes to the development of appropriate chemical strategies for biological scaffolds and the identification of implantable routes to overcome adverse immune reactions.

Summary: This study demonstrates that kidneys from extended uDCD, without aCPR/EC, can be salvaged using thrombolytic treatment to remove fibrin thrombi while preserving histology. These kidneys can then be transplanted with clinically acceptable early function.

Wnt ligands 3a and 5a regulate proliferation and migration in human fetal liver progenitor cells

Zhiwen Liu, Vijay Kumar Kuna, Bo Xu, Suchitra Sumitran-Holgersson

Summary: This study demonstrates that Wnt3a and Wnt5a may enhance the proliferation and migration of hFLPC by regulating key target genes, potentially playing an important role in liver regeneration processes. Incorporating recombinant human Wnt3a and Wnt5a in regenerative strategies using liver stem/progenitor cells could potentially improve the process of liver regeneration.
