Mesenchymal stromal cells are a population of undifferentiated multipotent adult cells possessing extensive self-renewal properties and the potential to differentiate into a variety of mesenchymal lineage cells. They express broad anti-inflammatory and immunomodulatory activity on the immune system and after transplantation can interact with the surrounding microenvironment, promoting tissue healing and regeneration. For this reason, mesenchymal stromal cells have been widely used in regenerative medicine, both in preclinical and clinical settings...

BACKGROUND: The previously reported SECA study demonstrated a dramatic 5-year survival improvement in patients with unresectable colorectal liver metastases (CLM) treated with liver transplantation (LT) compared with chemotherapy. The objective of this study was to assess whether immunosuppressive therapy accelerates the growth of pulmonary metastases in patients transplanted for unresectable CLM. METHODS: Chest CT scans from 11 patients in the SECA study resected for 18 pulmonary metastases were reviewed retrospectively...

Importance: Solid organ transplant recipients (SOTRs) have a 100-fold increased risk of squamous cell carcinoma (SCC), and they may develop more aggressive SCCs compared with immunocompetent individuals. Objective: To compare outcomes associated with aggressive behavior of SCC in SOTRs and high-risk immunocompetent patients. Design, Setting, and Participants: A retrospective cohort study of 58 SOTRs and 40 immunocompetent patients evaluated at the Yale Transplant Dermatology Clinic in New Haven, Connecticut, who had at least 1 SCC confirmed histopathologically between January 1, 2008, and December 31, 2015...

Liver transplantation (LT) has originally been designed to treat hepatobiliary malignancies. The initial results of LT for hepatocellular cancer (HCC) were, however, dismal this mainly due to the poor patient selection procedure. Better surgical and perioperative care and, especially, the refinement of selection criteria led to a major improvement of results, making HCC nowadays (again!) one of the leading indications for LT. This evolution is clearly shown by the innumerable reports aiming to further extend inclusion criteria for LT in HCC patients...

STUDY QUESTION: Is testicular transplantation of in vitro propagated spermatogonial stem cells associated with increased cancer incidence and decreased survival rates in recipient mice? SUMMARY ANSWER: Cancer incidence was not increased and long-term survival rate was not altered after transplantation of in vitro propagated murine spermatogonial stem cells (SSCs) in busulfan-treated recipients as compared to non-transplanted busulfan-treated controls. WHAT IS KNOWN ALREADY: Spermatogonial stem cell autotransplantation (SSCT) is a promising experimental reproductive technique currently under development to restore fertility in male childhood cancer survivors...

Brain metastases are an increasing burden among breast cancer patients, particularly for those with HER2(+) and triple negative (TN) subtypes. Mechanistic insight into the pathophysiology of brain metastases and preclinical validation of therapies has relied almost exclusively on intracardiac injection of brain-homing cells derived from highly aggressive TN MDA-MB-231 and HER2(+) BT474 breast cancer cell lines. Yet, these well characterized models are far from representing the tumor heterogeneity observed clinically and, due to their fast progression in vivo, their suitability to validate therapies for established brain metastasis remains limited...

Glycolysis and glutaminolysis are heavily involved in the metabolic reprogramming of cancer cells. The activation of oncogenes and inactivation of tumor suppressor genes has a marked effect on the cellular metabolic processes glycolysis and glutaminolysis. N-Myc downstream-regulated gene 2 (NDRG2) is a tumor suppressor gene that previous studies have demonstrated can inhibit the growth, proliferation and metastasis of clear cell renal cell carcinoma (ccRCC) cells. However, the function of NDRG2 in ccRCC metabolism remains unknown...

Dendritic cellular therapies and dendritic cell vaccines show promise for the treatment of autoimmune diseases, the prolongation of graft survival in transplantation, and in educating the immune system to fight cancers. Cell surface glycosylation plays a crucial role in the cell-cell interaction, uptake of antigens, migration, and homing of DCs. Glycosylation is known to change with environment and the functional state of DCs. Tolerogenic DCs (tDCs) are commonly generated using corticosteroids including dexamethasone, however, to date, little is known on how corticosteroid treatment alters glycosylation and what functional consequences this may have...

The capture of peritoneal metastatic cancer stem cell of human gastric cancer (pMCSC-hGC) is important to further understand the mechanism of peritoneal metastasis in gastric cancer patients. Previously, cancer stem cells (CSCs) of gastric and rectal cancers were captured and identified. However, the bottleneck of capturing pMCSC-hGC may be the scarce surgical specimen and limited volume of peritoneal metastatic lesions from gastric cancer. Only 5.2% of patients were diagnosed of unpredictive peritoneal seeding intraoperatively, while none cell sphere were successfully formed through the identical culture approach based on peritoneal metastatic nodules...

In recent years, experimental studies demonstrated negative impacts of impaired body stress response on colonic pathologies. In this study, we tested if reducing body stress response by the use of β-endorphin (BEP) neuronal transplants in the hypothalamus suppresses pre-neoplastic and neoplastic lesions. Colon cancer was induced by injecting 1,2-dimethylhydrazine (DMH) for sixteen weeks in Sprague Dawley rats with BEP neuron transplants or control neuron transplants, and their colonic histopathologies, colon tissue levels of pro-inflammatory cytokines and epithelial-mesenchymal transition (EMT) proteins and splenic levels of cytotoxic proteins were measured...

Galectin-1 has previously been shown to be strongly expressed in activated pancreatic stellate cells (PSCs) and promote the development and metastasis of pancreatic ductal adenocarcinoma (PDAC). However, the molecular mechanisms by which Galectin-1 promotes the malignant behavior of pancreatic cancer cells remain unclear. In this study, we examined the effects of Galectin-1 knockdown or overexpression in PSCs co-cultured with pancreatic cancer (PANC-1) cells. Immunohistochemical analysis showed expression of epithelial-mesenchymal transition (EMT) markers and MMP9 were positively associated with the expression of Galectin-1 in 66 human PDAC tissues...

Background and Objective: Our previous study showed that liver graft injury not only promotes tumor recurrence, but also induces chemoresistance in recurrent HCC after liver transplantation. Recently, we found that the hemoglobin-based oxygen carrier"YQ23" significantly ameliorates hepatic IR injury and prevent tumor recurrence. Here, we intended to explore the novel therapeutic strategy using oxygen carrier "YQ23"to sensitize chemotherapy in HCC. Methods: To investigate the role of YQ23 combined with Cisplatin, the proliferation of HCC cells was examined under combined treatment by MTT and colony formation...

Background: Raising T-cell response against antigens either expressed on normal and malignant plasma cells (e.g. HM1.24) or aberrantly on myeloma cells only (e.g. cancer testis antigens, CTA) by vaccination is a potential treatment approach for multiple myeloma. Results: Expression by GEP is found for HM1.24 in all, HMMR in 318/458 (69.4%), MAGE-A3 in 209/458 (45.6%), NY-ESO-1/2 in 40/458 (8.7%), and WT-1 in 4/458 (0.8%) of samples with the pattern being confirmed by RNA-sequencing...

Background: Few studies have analysed the impact of chronic respiratory disease (CRD) on outcomes in dialysis. We therefore sought to describe patients with CRD and end-stage renal disease and their outcomes after dialysis start, compared with patients without CRD, focusing especially on causes of death, access to renal transplantation and causes of hospital admissions. Methods: The study included 52 797 adults aged 18 years and older who began dialysis from 2008 to 2013 and are recorded in the French national REIN registry...

AIMS: Although the epidermal growth factor receptor (EGFR) and Wnt/β-catenin signaling systems synergistically regulate many essential developmental and regenerative processes in lung cancer, the mechanisms of their crosstalk remain poorly defined. Our study aimed to investigate an interaction between EGFR and the β-catenin signal. RESULTS: In this study, we described a potent activation of β-catenin by EGFR, which is dependent of the PtdIns3K/AKT pathway. We found EGF activated β-catenin signaling via phosphorylation of EGFR and AKT in EGFR-mutated PC-9 lung cancer cells...

Severe Combined ImmunoDeficiency (SCID) is defined as the lack or impairment of an adaptive immune system. Although SCID phenotypes are characteristically absent of T and B cells, many such SCID cellular profiles include the presence of NK cells. In human SCID patients, functional NK cells may impact the engraftment success of life saving procedures such as bone marrow transplantation. However, in animal models, a T cell-, B cell-, NK cell+ environment provides a valuable tool for asking specific questions about the extent of the innate immune system function as well as emerging NK targeted therapies against cancer...

Background: MicroRNAs are considered as potential regulators in various biological pathways and contribute to the diagnosis and prognosis of cancers. MicroRNA-214-3p (miR-214-3p) was proved to be correlated with various cancers in recent studies. However, the biological functions of miR-214-3p in hepatocellular carcinoma (HCC) and its association with the prognosis of HCC after liver transplantation are still unevaluated. Here we intended to elucidate the functional implication of miR-214-3p in regulation of cell proliferation and apoptosis and its potential prediction of clinical prognosis of HCC patients...
