Organ donors are sources of physiologically healthy organs and tissues for life-saving transplantation, and have been recently used for human immunology studies which are typically confined to the sampling of peripheral blood. Donors comprise a diverse population with different causes of death and clinical outcomes during hospitalization, and the effects of such variations on immune parameters in blood and tissues are not known. We present here coordinate analyses of innate and adaptive immune components in blood, lymphoid (bone marrow, spleen, lymph nodes), and mucosal (lungs, intestines) sites from a population of brain-dead organ donors (3-months-93-years; n=291) across eight clinical parameters...

Skeletal muscle regeneration is a complex interplay between various cell types including invading macrophages. Their recruitment to damaged tissues upon acute sterile injuries is necessary for necrotic debris clearance and for coordination of tissue regeneration. This highly dynamic process is characterized by an in-situ transition of infiltrating monocytes from an inflammatory (Ly6C(high) ) to a repair (Ly6C(low) ) macrophage phenotype. The importance of the macrophage phenotypic shift and the cross-talk of the local muscle tissue with the infiltrating macrophages during tissue regeneration upon injury are not fully understood and their study lacks adequate methodology...

Clinical practice variations are a barrier to the study of pediatric heart transplants and coordination of multicenter RCTs in this patient population. We surveyed centers to describe practice patterns, understand areas of variation, and willingness to modify protocol. Pediatric heart transplant centers were identified, and one survey was completed per center. Simple descriptive statistics were used. The response rate was 77% (40 responses from 52 contacted centers, 37 with complete responses). Median center volume of respondents was eight transplants/year (IQR 3-19)...

Spinocerebellar ataxia 3 (SCA3), which is a progressive neurodegenerative disease, is currently incurable. Emerging studies have reported that human umbilical cord mesenchymal stem cells (HUC-MSCs) transplantation could be a promising therapeutic strategy for cerebellar ataxias. However, few studies have evaluated the effects of HUC-MSCs on SCA3 transgenic mouse. Thus, we investigated the effects of HUC-MSCs on SCA3 mice and the underlying mechanisms in this study. SCA3 transgenic mice received systematic administration of 2 × 10(6) HUC-MSCs once per week for 12 continuous weeks...

The prevalence of autologous and allogeneic hematopoietic cell transplantation (HCT) survivors continues to increase. Among patients whose disease remains in remission for the first 2-5years after transplantation, it is estimated that approximately 80-90% will be alive over the subsequent 10years. However, the relative mortality rates of such patients continue to remain higher than those of their general population peers, with late complications contributing to significant long-term morbidity and mortality...

The development of the eye has been a topic of extensive investigation, from the early studies on tissue induction to more recent breakthroughs in resolving the mechanism regulating progenitor patterning and their gradual and coordinated differentiation into diverse tissue types that function together throughout life. Among the ocular tissue types, the retinal pigmented epithelium (RPE) is at the forefront of developmental biology and stem cell research. The growing interest in this lineage stems from its importance for photoreceptor function as well as from its requirement during embryogenesis for the development of the photoreceptors and the choroid...

Nocardiosis is primarily an opportunistic infection caused by aerobic Gram-positive bacteria of the genus Nocardia. In this case report we describe a male patient who previously received a kidney transplant and was admitted to hospital with chills, headache and pain in the neck and left eye, tremor and coordination problems. A magnetic resonance scan of the brain showed multiple abscesses, and blood culture was positive for Nocardia farcinica. Nocardiosis of the central nervous system is a rare, but serious differential diagnosis in immunosuppressed patients with signs of high intracranial pressure...

The purpose of this study was to evaluate the changes in magnitude of three-dimensional (3D) liver motion after liver resection/transplantation in patients with hepatocellular carcinoma (HCC) using four-dimensional (4D)-computed tomography (CT) images. From January 2012 to April 2016, 74 HCC patients underwent 4D-CT scans under a free-breathing state to assess respiratory liver motion. Of the 74 patients, 40 did not have a liver resection/transplantation (Group A), 34 with liver resection/transplantation. 15 underwent major or minor resection in the right liver lobe (Group B), 14 underwent major or minor resection in the left liver lobe (Group C), and five underwent liver transplantation (Group D)...

Mucopolysaccharidosis type 1 (MPS1) is an inherited lysosomal storage disorder caused by a deficiency in the glycosaminoglycan (GAG)-degrading enzyme α-l-iduronidase (IDUA). In affected patients, the systemic accumulation of GAGs results in skeletal dysplasia, neurological degeneration, multiple organ dysfunction, and early death. Current therapies, including enzyme replacement and bone marrow transplant, improve life expectancy but the benefits to skeletal and neurological phenotypes are limited. In this study, we tested the therapeutic efficacy of liver-directed transplantation of a placental stem cell, which possesses multilineage differentiation potential, low immunogenicity, and high lysosomal enzyme activity...

INTRODUCTION: In 2013, a total of 1586 kidney transplants were performed in Japan, and 1431 (90.2%) of the organs were from living donors. The purpose of this study is to illuminate the awareness of living kidney donors toward kidney donation after the condition of the recipient changed, thus clarifying the influence of that recognition on the donor. METHODS: This study design was qualitative descriptive research. Transplant coordinators at 4 hospitals were commissioned to screen subject candidates and hand-deliver printed research explanations to them...

STUDY QUESTION: Can traceability of gametes and embryos be ensured during IVF? SUMMARY ANSWER: The use of a simple and comprehensive traceability system that includes the most susceptible phases during the IVF process minimizes the risk of mismatches. WHAT IS KNOWN ALREADY: Mismatches in IVF are very rare but unfortunately possible with dramatic consequences for both patients and health care professionals. Traceability is thus a fundamental aspect of the treatment...

Neural stem cells have been considered as a source of stem cells that can be used for cell replacement therapies in neurodegenerative diseases, as they can be isolated and expanded in vitro and can be used for autologous grafting. However, due to low percentages of survival and varying patterns of differentiation, strategies that will enhance the efficacy of transplantation are under scrutiny. Here, we have examined whether alterations in Geminin's expression, a protein that coordinates the balance between self-renewal and differentiation, can improve the properties of stem cells transplanted in 6 OHDA hemiparkinsonian mouse model...

REVIEW

Corneal transplantation is among the most prevalent and successful forms of solid tissue transplantation in humans. Failure of corneal allograft is mainly due to immune-mediated destruction of the graft, a complex and highly coordinated process that involves elaborate interactions between cells of innate and adaptive immunity. The migration of immune cells to regional lymphoid tissues and to the site of graft plays a central role in the immunopathogenesis of graft rejection. Intricate interactions between adhesion molecules and their counter receptors on immune cells in conjunction with tissue-specific chemokines guide the trafficking of these cells to the draining lymph nodes and ultimately to the site of graft...
