Project description:RNA-seq data from short term cultivated fibroblasts were sequenced on an Illumina HiSeq 2000 sequencer. Donors were differentiated by age (Years) and gender (F=female; M=male). Two samples were obtained from each individual from different locations (B=buttock, not UV exposed; S=shoulder, UV exposed).

Project description:Primary graft dysfunction (PGD) continues to be a major cause of early death after lung transplantation. Moreover, there remains a lack of accurate pre-transplant molecular markers for predicting PGD. To identify distinctive gene expression signatures associated with PGD, we profiled human donor lungs using microarray technology prior to the graft implantation. The genomic profiles of 10 donor lung samples from patients who subsequently developed clinically defined severe PGD were compared with 16 case-matched donor lung samples from those who had a favorable outcome without PGD. Matched factors used were: recipient age (± 10 years), recipient gender, recipient lung disease, and type of transplantation (single or bilateral). Keywords: Observational case-control study

Project description:This study was conducted in order to evaluate the effects of high-pressure processing, UV-C irradiation and thermo-ultrasonication on donor human milk safety and quality. The results of these methods were then compared with holder pasteurization, which is the current recommended treatment for donor human milk.

Project description:Lung donation after cardiac death (DCD), in contrast to donation after brain death (DBD), is a promising and increasingly common method to help relieve the shortage of donor organs. However, the pathogenetic consequences of retrieved lungs after DCD vs. DBD have not been clarified. We aimed to study the differential gene expression profiles in lungs of DCD and DBD patients.

Project description:Background: Skin homeostasis is mediated by dermal fibroblasts and is affected by aging. Although age-related heterogeneity in fibroblasts has been reported, the effects of donor and species on this heterogeneity are unclear. Methods: To analyze age-related transcriptomic changes in human dermal fibroblasts, single-cell RNA sequencing was performed on dermal fibroblasts (ASF-4 cells) collected from the inner forearm of a volunteer over three decades. Results: Four main cell subpopulations changed with donor age and showed proliferative, homeostasis, fibrotic, and senescence functional annotations. The downregulation of the expression of genes encoding key extracellular matrix production and mechanotransduction components decreased with donor age. Interestingly, dermal fibroblasts have two putative differentiation pathways: one that involves the acquisition of senescent properties and the acquisition of fibrotic properties without the suppression of proliferation. Aging induced fibroblast differentiation in a manner involving the acquisition of senescent properties. Conclusion:Reconciling the various aspects of fibroblast heterogeneity may provide insight into the mechanisms underlying human skin aging and associated phenomena, including wrinkles, sagging, delayed wound healing, and suppressed scar formation.

Project description:Our understanding of heart failure (HF) has been provided by indirect surrogates, such as post-mortem histology, cardiovascular imaging, and molecular characterisation in vivo and in vitro, rather than directly in pre-mortem human cardiac tissue. Using our heart bank of pre-mortem hearts procured according to the most stringent protocols, we examined ischemic (ICM) and dilated cardiomyopathy (DCM) -- the most common causes of HF and leading causes of cardiac transplantation1. We performed unbiased, comprehensive, paired proteomic and metabolomic analysis of 51 left ventricular (LV) samples from 44 cryopreserved pre-mortem human ICM and DCM hearts, including age-matched, healthy, histopathologically-normal donor controls of both genders for comparison. Data integration via pathway and correlation network analysis revealed overlapping and divergent disease pathways in ICM and DCM, and, strikingly, precise sex-specific differences within each disease that unveil the interaction of gender with HF. Identified core functional nodes in each disease may serve as novel therapeutic targets, and we provide all proteomic and metabolomic results via an interactive online repository (https://mengboli.shinyapps.io/heartomics/) as a publicly available resource.

Project description:This pilot phase II trial studies how well giving donor T cells after donor stem cell transplant works in treating patients with hematologic malignancies. In a donor stem cell transplant, the donated stem cells may replace the patient’s immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor’s T cells (donor lymphocyte infusion) after the transplant may help increase this effect.
