Medulloblastoma (MB), the most common malignant paediatric brain tumor, is currently treated using a combination of surgery, craniospinal radiotherapy and chemotherapy. Owing to MB stem cells (MBSCs), a subset of MB patients remains untreatable despite standard therapy. CD133 is used to identify MBSCs although its functional role in tumorigenesis has yet to be determined. In this work, we showed enrichment of CD133 in Group 3 MB is associated with increased rate of metastasis and poor clinical outcome. The signal transducers and activators of transcription-3 (STAT3) pathway are selectively activated in CD133(+) MBSCs and promote tumorigenesis through regulation of c-MYC, a key genetic driver of Group 3 MB...

Cancer cells, stem cells and cancer stem cells have for a long time played a significant role in the biomedical sciences. Though cancer therapy is more effective than it was a few years ago, the truth is that still none of the current non-surgical treatments can cure cancer effectively. The reason could be due to the subpopulation called "cancer stem cells" (CSCs), being defined as those cells within a tumour that have properties of stem cells: self-renewal and the ability for differentiation into multiple cell types that occur in tumours...

A 26-year-old woman developed symptoms of acute toxicity during cyclosporine (CsA) therapy for graft-versus-host disease prophylaxis. The standard regimen included CsA in a dose of 1.5 mg/kg (120 mg) every 12 h, but, as a medication error, she received a high dose of 500 mg of oral CsA. After 2 h, she developed nausea and vomiting and, subsequently, flushing, chest tightness, tremor and vertigo. Laboratory and clinical examinations revealed high blood CsA concentrations (1000 ng/mL after 12 h) with a mild increase in blood pressure...

Prostate cancer (PCa) is the second most frequent type of cancer in men worldwide and the levels of differentiation growth factor midkine (MK) are increased in PCa. Cancer and/or the treatment process itself may lead to psychiatric disorders. Lithium chloride (LiCl) has anti-manic properties and has been used in cancer therapy; however, it has a queried safety profile. In addition, cancer stem cells are responsible for the heterogeneous phenotype of tumor cells; they are involved in progression, metastasis, recurrence and therapy resistance in various cancer types...

In chronic myeloid leukemia (CML), the occurrence of blastic transformation is rare. Treatment outcome is generally poor. Allogeneic stem cell transplantation (allo-SCT) is the only potentially curative treatment option for advanced-phase CML. Infections caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) isolates are associated with high morbidity and mortality rates, particularly in patients with haematological malignancies. Infection and colonization by these multiresistant bacteria may represent a challenge in SCT recipients for the management of post-transplantation complications, as well as for the eligibility to receive a transplant in patients who acquire the pathogen prior to the procedure...

Liver diseases are the fourth leading cause of mortality among adults in the United States. Patients with chronic liver diseases such as viral hepatitis, fibrosis, and cirrhosis have significantly higher risks of developing hepatocellular carcinoma (HCC). With a dismal five-year survival rate of 11%, HCC is the third most common cause of cancer-related deaths worldwide. Regardless of the underlying cause, late presentation and a lack of effective therapy are the major impediments for successful treatment of HCC...

: An increase in epithelial cell permeability has been proposed to contribute to phosgene-induced acute lung injury (ALI). However, no specific and effective means for blocking increases in permeability are currently available. Cell-based therapy using bone marrow-derived mesenchymal stem cells (MSCs) is an attractive new approach. Canonical wnt/β-catenin signaling has been demonstrated to contribute to both epithelial cell injury and repair mechanisms in ALI. The goal of our study was to determine the effects of MSCs on epithelial permeability in phosgene-induced ALI in Sprague-Dawley (SD) rats and identify changes in major components of the wnt3a/β-catenin signaling pathway during this process...

Despite all attempts the problem of regeneration in damaged central nervous system (CNS) has remained challenging due to its cellular complexity and highly organized and sophisticated connections. In this regard, stem cell therapy might serve as a viable therapeutic approach aiming either to support the damaged tissue and hence to reduce the subsequent neurological dysfunctions and impairments or to replace the lost cells and re-establish damaged circuitries. Adult neural stem/progenitor cells (NS/PCs) are one of the outstanding cell sources that can be isolated from the subventricular zone (SVZ) of the lateral ventricles...

UNLABELLED: Cancer/testis antigens (CTAs) are named based on their expression pattern that is restricted in a number of normal and abnormal tissues. Tumor cells frequently express antigens whose expression is typically restricted to germ cells. Their unique expression pattern is guaranteed by precise epigenetic regulatory mechanisms. Because of their tumor-limited, high immunogenicity, and biased expression, discovery of these molecules provides unprecedented opportunities for further research and clinical development in the field of cancer diagnosis and immunotherapy...

Cancer stem cells (CSCs) are a small subpopulation of tumor cells with capabilities of self-renewal, dedifferentiation, tumorigenicity, and inherent chemo-and-radio therapy resistance. Tumor resistance is believed to be caused by CSCs that are intrinsically challenging to common treatments. A number of CSC markers including CD44, CD133, receptor tyrosine kinase, aldehyde dehydrogenases, epithelial cell adhesion molecule/epithelial specific antigen, and ATP-binding cassette subfamily G member 2 have been proved as the useful targets for defining CSC population in solid tumors...

Multipotent human bone marrow derived mesenchymal stem cells (hMSCs) improve functional outcome after experimental traumatic brain injury (TBI). The present study was designed to investigate whether systemic administration of cell-free exosomes generated from hMSCs cultured in 2-dimensional (2D) conventional conditions or in 3-dimensional (3D) collagen scaffolds promote functional recovery and neurovascular remodeling in rats after TBI. Wistar rats were subjected to TBI induced by controlled cortical impact; 24 h later tail vein injection of exosomes derived from hMSCs cultured under 2D or 3D conditions or an equal number of liposomes as a treatment control were performed...

Current therapies for acute myeloid leukemia (AML), are associated with high relapse rates. Hence, development of new therapeutic strategies is crucial to circumvent this problem. Bivalent antibody technology has been used to engineer novel antibody fragments with increased avidity, by assembling two scFv in a single molecule. Here, we present accompanying data from construction and characterization experiments of a biscFv antibody targeting CD123, the most important biomarker of leukemic cancer stem cells which play a key role in relapsed AML after chemotherapy...

Given the failure of pharmacological interventions in acute respiratory distress syndrome (ARDS), researchers have been actively pursuing novel strategies to treat this devastating, life-threatening condition commonly seen in the Intensive Care Unit. There has been considerable research on harnessing the reparative properties of stem and progenitor cells to develop more effective therapeutic approaches for respiratory diseases with limited treatment options like ARDS. This review will discuss the preclinical literature on the use of stem and progenitor cell therapy and cell-based gene therapy for the treatment of preclinical animal models of acute lung injury (ALI)...

INTRODUCTION: Much attention has been paid to the idea of cell therapy using stem cells from different sources of the body. Fat-derived stem cells that are called adipose derived stem cells (ADSCs) from stromal vascular fraction (SVF) are the subject of many studies in several cell therapy clinical trials. Despite production of some GMP-grade enzymes to isolate SVF for clinical trials, there are critical conditions like inconsistency in lot-to-lot enzyme activity, endotoxin residues, other protease activities and cleavage of some cell surface markers which significantly narrow the options...

Nutritional research in sickle cell disease has been the focus in recent times owing to not only specific nutritional deficiencies, but also the improvements associated with less painful episodes. Though hydroxyurea remains the drug of choice, certain adverse health effects on long term supplementation makes room for researches of different compounds. Macro and micro nutrient deficiencies, along with vitamins, play an important role in not only meeting the calorific needs, but also reducing clinical complications and growth abnormalities...
