B-cell prolymphocytic leukemia (B-PLL) is a rare lymphoid neoplasm with an aggressive clinical course. Treatment strategies for B-PLL remain to be established, and, until recently, alemtuzumab was the only effective therapeutic option in patients harboring 17p deletions. Herein, we describe, for the first time, a case of B-cell prolymphocytic leukemia harboring a 17p deletion in a 48-year-old man that was successfully treated sequentially with idelalisib-rituximab/ibrutinib followed by allogeneic hematopoietic stem cell transplant (allo-HSCT)...

Objectives: IFNα can stimulate an antitumor immune response and has a direct inhibition on cancer cells. This study is to test whether IFNα can activate dormant cancer stem cell (CSC) in oral squamous cell carcinoma (OSCC) to facilitate their elimination by chemotherapy. Materials and methods: Nude mouse transplantation tumor model was established and administrated with IFNα and saline. The influence on CD44 and ALDH1A1 expression under IFNα treatment was detected by in vivo experiments. Flow cytometry, western blot, and immunofluorescence were used to detect the expression of CD44 and ALDH1A1 after INFa treatment in OSCC cell lines...

Lymphangiogenesis plays an important role in cancer metastasis. Bone marrow-derived mesenchymal stem cells (BMMSCs) migrate to the site of tumorigenesis and in turn promote the metastasis. However, whether BMMSCs involve in the lymphangiogenesis of lung cancer is unclear. Jinfukang has clinically been used for the treatment of non small cell lung cancer (NSCLC) in China. In this study, to investigate the involvement of BMMSCs in lymphangiogenesis in lung cancer, and evaluate the inhibitory effect of Jinfukang on the lymphangiogenesis, chimeric mice were prepared by transplanting bone marrow from green fluorescent protein (GFP) transgenic mice (C57BL/6-EGFP) into irradiated C57BL/6 mice...

Cytokines provide signals that regulate immature normal and acute myeloid leukemia (AML) cells in the bone marrow microenvironment. We here identify interleukin 4 (IL4) as a selective inhibitor of AML cell growth and survival in a cytokine screen using fluorescently labeled AML cells. RNA-sequencing of the AML cells revealed an IL4-induced upregulation of Stat6 target genes and enrichment of apoptosis-related gene expression signatures. Consistent with these findings, we found that IL4 stimulation of AML cells induced Stat6 phosphorylation and that disruption of Stat6 using CRISPR/Cas9-genetic engineering rendered cells partially resistant to IL4-induced apoptosis...

Pluripotent stem cell-derived cardiomyocytes show great promise in regenerating the heart after myocardial infarction; however, several uncertainties exist that must be addressed before clinical trials. One practical issue is graft survival following transplantation. Although a pro-survival cocktail with Matrigel has been shown to enhance graft survival, the use of Matrigel may not be clinically feasible. The purpose of this study was to test whether a hyaluronan-based hydrogel, HyStem, could be a substitute for Matrigel...

The success of mesenchymal stem cell transplantation is highly dependent on their survival and controlled fate regulation. This study demonstrates that dual-delivery of connective tissue growth factor (CTGF) and fibroblast growth factor 2 (FGF-2) from a core-shell fiber of Silk Fibroin/poly(L-lactic acid-co-ε-caprolactone)-polyethylene oxide (SF/PLCL-PEO) enhanced fibrogenic lineage differentiation of MSCs. The core-shell structure was confirmed by transmission electron microscopy (TEM), fluorescence microscopy and attenuated total reflection (ATR) Fourier transform infrared (FTIR) spectroscopy...

Despite recent advances in lymphoma treatment, mantle cell lymphoma (MCL) remains incurable and we are still unable to identify patients who will not benefit from the current standard-of-care. Here, we explore the prognostic value of recurrent genetic aberrations in diagnostic bone marrow (BM) specimens from 183 younger MCL patients from the Nordic MCL2 and MCL3 trials, which represent current standard-of-care regimens. In the univariate model, mutations of TP53 (11%) and NOTCH1 (4%), and deletions of TP53 (16%) and CDKN2A (20%) were significantly associated with inferior outcomes (together with MIPI, MIPI-c, Blastoid morphology and Ki67>30%); however, in multivariate analyses only TP53 mutations (HR=6...

A xenograft model of stem cell rejection was developed by co-transplantating human CD34+ and allogeneic CD3+ T cells into NOD-scid ɣ-chain(null) (NSG) mice. T cells caused graft failure when transplanted at any CD34:CD3 ratio between 1:50 to 1:0.1. Kinetics experiments showed that two weeks after transplantation CD34+ cells engrafted the marrow and T cells expanded in the spleen. Then at four weeks only memory T cells populated both sites and rejected CD34+ cells. Blockade of T cell costimulation was tested by injecting the mice with abatacept (CTLA4-IgG1) from day -1 to +27 (Group A), or from day -1 to +13 (Group B), or from day +14 to +28 (Group C)...

BACKGROUND AIMS: Urothelial bladder cancer (UBC) is the second most common cancer of the genitourinary tract and for advanced forms of the disease it has a high mortality rate. There are no approved new molecularly targeted agents or chemotherapeutics for advanced UBC beyond cisplatin-based chemotherapy except the recently approved anti-programmed death ligand 1 (anti-PD-1/PD-L1) antibody. With complex genetic and epigenetic alterations in tumors, despite several druggable targets identified, to cure UBC is still a challenging unmet medical need...

BACKGROUND: Nephroblastoma and neuroblastoma belong to the most common abdominal malignancies in childhood. Similarities in the initial presentation may provide difficulties in distinguishing between these two entities, especially if unusual variations to prevalent patterns of disease manifestation occur. Because of the risk of tumor rupture, European protocols do not require biopsy for diagnosis, which leads to misdiagnosis in some cases. CASE PRESENTATION: We report on a 4½-year-old girl with a renal tumor displaying radiological and laboratory characteristics supporting the diagnosis of nephroblastoma...

Transduction of hematopoietic stem and progenitor cells (HSPC) with therapeutic lentiviral vectors (LVs) constitutes a new therapeutic option for the treatment of different monogenic diseases affecting the lympho-hematopoietic system. The development of detailed preclinical studies of gene therapy in animal disease models constitutes an essential step in expanding the application of gene therapy in a wide variety of inherited and acquired diseases. Here we describe an efficient protocol to transduce HSPCs from wild-type and Fanconi anemia mice with either gene marking or therapeutic LVs...

PURPOSE OF REVIEW: In recent years, the rules of engagement between natural killer (NK) cells and their targets have become better defined with the identification of an array of NK surface molecules, notably the killer immunoglobulin-like (KIR) receptors and their ligands on target cells through which signals of activation or suppression of NK function are mediated. After allogeneic stem cell transplantation (SCT), the opportunity for NK cell activation can occur both in human leucocyte antigen (HLA) matched and HLA mismatched pairs...

The use of extracorporeal life support (ECLS) as ultimate salvage therapy for hematopoietic stem cell transplant recipients remains controversial among oncologists and critical care specialists. Prognosis is poor, particularly after allogeneic transplantation, and literature to guide clinical decision-making is scarce. Our report describes successful ECLS in a pediatric patient undergoing allogeneic hematopoietic stem cell transplantation, who developed acute respiratory failure during severe neutropenia, followed by immediate neutrophil engraftment...

Leukemic relapse in the central nervous system (CNS) after conventional treatment is associated with a poor prognosis. The effectiveness and safety of IV infusion of human leukocyte antigen (HLA)-mismatched lymphocytes for leukemia, and intrathecal (IT) infusion of HLA-mismatched lymphocytes for cerebrospinal fluid (CSF) dissemination of medulloblastoma have been reported. A 13-year-old girl (HLA-A31) was diagnosed as relapsing from Philadelphia chromosome-positive acute leukemia in the CNS after receiving chemotherapy, tyrosine kinase inhibitors, haploidentical hematopoietic stem cell transplantation (HSCT) from her father (HLA-A31), and craniospinal irradiation...

Limbal stem cell defect model is an important animal model that provides a basis for the study of ocular surface diseases. The rabbit cornea is of moderate size and is widely used in such studies as an experimental animal model. At present, the main modeling methods are alkali burns, and corneal limbus girdling and corneal epithelium doctoring. Each method has its own characteristics. In this study, we observed rabbit models with severe ocular surface defect established by the two methods and changes after amniotic membrane transplantation...
