NEK2 is a member of the NIMA-related family of serine/threonine centrosomal kinases. We analyzed the relationship between differential expression of NEK2 and hepatocellular carcinoma (HCC) patient outcomes after liver transplants. We also studied the microRNAs that affect NEK2 expression. Analysis of multiple microarrays in the Oncomine database revealed that NEK2 expression was higher in HCC tissues than adjacent normal liver tissues. High NEK2 expression correlated with tumor size, pathological grade and macro- and microvascular invasion...

The current methods for melanocyte delivery to depigmented skin are invasive and often require sophisticated approaches. Here we describe a promising simple and minimally invasive technique based on the dermarolling system. The technique involves preparation of a keratinocyte/melanocyte suspension prepared by trypsinization from a non-lesioned part of a patient's scalp skin and transepidermal delivery using a dermaroller equipped with 0.2 mm needles. Dermarolling leads to epidermal microinjuries without, however, causing pain or inflammation...

Mesenchymal stem cell (MSC) transplantation alone may be insufficient for treatment of liver fibrosis because of complicated histopathological changes in the liver. Given that miR-122 plays an essential role in liver fibrosis by negatively regulating the proliferation and transactivation of hepatic stellate cells (HSCs), this study investigated whether miR-122 modification can improve the therapeutic efficacy of adipose tissue-derived MSCs in treating liver fibrosis. MiR-122-modified AMSCs (AMSC-122) were constructed through lentivirus-mediated transfer of pre-miR-122...

Tracheal replacement for the treatment of end-stage airway disease remains an elusive goal. The use of tissue-engineered tracheae in compassionate use cases suggests that such an approach is a viable option. Here, a stem cell-seeded, decellularized tissue-engineered tracheal graft was used on a compassionate basis for a girl with critical tracheal stenosis after conventional reconstructive techniques failed. The graft represents the first cell-seeded tracheal graft manufactured to full good manufacturing practice (GMP) standards...

BACKGROUND / AIMS: An easily available tooth storage medium is required to preserve a tooth after avulsion. Milk and Hank's balanced salt solution (HBSS) are recommended as tooth storage media, and egg white is also reported to be comparable with milk. The aim of the present study was to histologically and immunohistochemically evaluate the effect of different tooth storage media on the periodontal ligament (PDL) of extracted teeth. MATERIAL AND METHODS: This experiment used HBSS, milk and egg white as tooth storage media...

EDITORIAL
M E Snyder, D L Farber
T cell depletion is widely used as induction therapy in solid organ transplants and particularly in kidney transplantation, to reduce the episodes of acute cellular rejection. The resultant reduction in T cell numbers is usually temporary, as T cells are actively replenished due to thymic output and/or lymphopenia-induced proliferation of remaining, depletion-resistant T cells. However, the extent of T cell replenishment and the persistence of lymphopenia varies between individuals, with potential impacts on protective or pathogenic immune responses...

We aimed to determine a correlation between cytomegalovirus reactivation post hematopoeitic stem cell transplantation (post-HSCT) with the type of graft source, defining children at risk. We analyzed data on children less than 18 years of age undergoing HSCT from 2002 to May 2016 (n = 464). Correlation between reactivation and graft source was analyzed statistically. Reactivation occurred in 3% of children with matched-related donor (MRD) transplants, 33.3% with unrelated peripheral blood stem cells, 17.4% with unrelated cords, and 36...

REVIEW
Rinat Meir, Rachela Popovtzer
Cell-based therapies utilize transplantation of living cells with therapeutic traits to alleviate numerous diseases and disorders. The use of such biological agents is an attractive alternative for diseases that existing medicine cannot effectively treat. Although very promising, translating cell therapy to the clinic has proven to be challenging, due to inconsistent results in preclinical and clinical studies. To examine the underlying cause for these inconsistencies, it is crucial to noninvasively monitor the accuracy of cell injection, and cell survival and migration patterns...

The objective of this review is to explore the available literature on solid renal masses (SRM) in transplant allograft kidneys to better understand the epidemiology and management of these tumors. A literature review using PubMed was performed according to the PRISMA methodology. Fifty-six relevant studies were identified from 1988-2015. A total of 174 SRMs in 163 patients, were identified with a mean tumor size of 2.75 cm (0.5-9.0cm). Tumor histology was available in 164 (94.3%) tumors: clear cell renal cell carcinoma (RCC) (45...

The advent of novel strategies to generate leukemia-associated-antigen (LAA)-specific T cells for adoptive immunotherapies creates a demand for standardized good laboratory practice (GLP)-compliant enumeration assays to provide a secure clinical environment-whether it is to identify potential donors, define therapeutic doses for transplantation, or monitor clinical success. Here, we introduce a no-wash assay based on single-platform cell enumeration and Streptamer staining to determine the Wilms' tumor antigen 1 (WT1)-specific T cell immunity in clinical samples...

INTRODUCTION: Corneal burn grade IV usually leads to blindness. Several different surgical techniques remain challenging owing to the extensive tissue damage. Here, we introduce a novel technique with a 15 mm corneoscleral and limbal homologous graft combined with sequential autologous corneal removal ab interno, with a vitrectomy probe to save the anterior chamber angle. In vivo anatomy with optical coherence tomography is the surgical key. METHOD: A large 15 mm sclerocorneal graft is sutured on top of the remainder of the destroyed cornea and sclera after removal of the epithelium and conjunctiva, with anterior synechiolysis if necessary, peripheral iridectomy and conjunctivoplasty...

Solitary plasmacytoma (SP) and Plasma cell leukemia (PCL) are uncommon (3-6%) types of plasma cell disease. The risk of progression to symptomatic multiple myeloma (MM) is probably important for the outcome of SP. PCL is rare and has a dismal outcome. In this study we report on incidence and survival in PCL/SP, and progression to MM in SP, using the prospective observational Swedish Multiple Myeloma Register designed to document all newly diagnosed plasma cell diseases in Sweden since 2008. Both solitary bone plasmacytoma (SBP), (n=124) and extramedullary plasmacytoma (EMP), (n=67) have better overall survival (OS) than MM (n=3549)...

Belatacept, a T cell costimulation-blocker demonstrated superior renal function, lower cardiovascular risk, and improved graft/patient survival in renal transplant recipients. Despite the potential benefits, adoption of belatacept has been limited in part due to concerns regarding higher rates and grades of acute rejection in clinical trials. Since July 2011 we have utilized belatacept-based immunosuppression regimens in clinical practice. In this retrospective analysis of 745 patients undergoing renal transplantation at our center, we compared patients treated with belatacept (n=535) to a historical cohort receiving a tacrolimus-based protocol (n=205)...

Tyrosine kinase inhibitors (TKIs) are widely used to treat patients with chronic myelogenous leukemia in the chronic phase (CML-CP), and outcomes of TKI treatment for patients with CML-CP have been excellent. Since multiple TKIs are currently available, second-line or third-line TKI therapy is considered for patients who are intolerant of or resistant to the previous TKI treatment. Therefore, allogeneic hematopoietic stem cell transplantation (allo-HSCT) is considered only for patients with disease progression or for patients after treatment failure with multiple TKIs...

BACKGROUND: Cellular therapy of human embryonic stem cell-derived cardiomyocytes (hES-CMs) holds great promise for regenerating infarcted cardiac tissues. Yet, the major challenge remains as little cells survived after grafting. In this study, we examined whether treating hES-CMs with 7, 8, 3'-Trihydroxyflavone (THF) may improve hES-CMs developments both in vitro and in vivo. METHOD: HES-CMs were differentiated in vitro, and treated with 5 μ59M THF for 24 h...

The PI3K/mTOR signaling cascade is fundamental in T-cell activation and fate decisions. We showed the distinct regulation of PI3K/mTOR in regulatory and effector T-cells and proposed the potential therapeutic benefit of targeting this pathway to control the balance between effector and regulatory T-cell activities. Substantial adverse effects in long-term clinical usage of Rapamycin suggest the use of alternative treatments in restraining effector T-cell function in transplant patients. We hypothesize that dual PI3K/mTOR inhibitors may represent an immunosuppressant alternative...

The transplantation of rodent Schwann cells (SCs) provides anatomical and functional restitution in a variety of spinal cord injury (SCI) models, supporting the recent translation of SCs to phase 1 clinical trials for human SCI. Whereas human (Hu)SCs have been examined experimentally in a complete SCI transection paradigm, to date the reported behavior of SCs when transplanted after a clinically relevant contusive SCI has been restricted to the use of rodent SCs. Here, in a xenotransplant, contusive SCI paradigm, the survival, biodistribution, proliferation and tumorgenicity as well as host responses to HuSCs, cultured according to a protocol analogous to that developed for clinical application, were investigated...

BACKGROUND: Pure red cell aplasia (PRCA) is a well-documented potential side effect of ABO major mismatched allogeneic hematopoietic stem cell transplants. This side effect may be self-limiting, but is sometimes treated using modalities such as steroids, antithymocyte globulin, donor lymphocyte infusions, rituximab, or plasma exchanges. Another well-documented cause of pure red cell aplasia is a chronic parvovirus B19 infection, which may be seen in immunocompromised hosts. The treatment of this cause of PRCA includes removal of immunosuppression, intravenous immunoglobulin (IVIg), or rituximab; however, this condition may also be self-limiting...

Decellularized human livers are considered the perfect extracellular matrix (ECM) surrogate because both three-dimensional architecture and biological features of the hepatic microenvironment are thought to be preserved. However, donor human livers are in chronically short supply, both for transplantation or as decellularized scaffolds, and will become even scarcer as life expectancy increases. It is hence of interest to determine the structural and biochemical properties of human hepatic ECM to derive design criteria for engineering biomimetic scaffolds...
