UNLABELLED Background In vitro proliferative and differentiation potential of mesenchymal stromal cells generated from CD271(+) bone marrow mononuclear cells (CD271-mesenchymal stromal cells) has been demonstrated in several earlier and recent reports. In the present study we focused, in addition to proliferative and differentiation potential, on in vitro(More)
Previous studies have shown that children with acute myeloid leukemia (AML) who developed mixed chimerism (MC) were at high risk for relapse after allogeneic stem-cell transplantation (allo-SCT). We investigated the feasibility of intensified preemptive immunotherapy in children receiving allo-SCT for AML. Eighty-four children were registered in our trial(More)
BACKGROUND AIMS Cytokine-induced killer (CIK) cells may serve as an alternative approach to adoptive donor lymphocyte infusions (DLI) for patients with acute leukemia relapsing after haplo-identical hematopoietic stem cell transplantation (HSCT). We investigated the feasibility of enhancing CIK cell-mediated cytotoxicity by interleukin (IL)-15 against acute(More)
BACKGROUND Rhabdomyosarcoma is the most common soft tissue sarcoma in childhood and has a poor prognosis. Here we assessed the capability of ex vivo expanded cytokine-induced killer cells to lyse both alveolar and embryonic rhabdomyosarcoma cell lines and investigated the mechanisms involved. DESIGN AND METHODS Peripheral blood mononuclear cells from six(More)
Allogeneic stem cell transplantation (allo-SCT) has become an important treatment modality for patients with high-risk acute myeloid leukemia (AML) and is also under investigation for soft tissue sarcomas. The therapeutic success is still limited by minimal residual disease (MRD) status ultimately leading to patients' relapse. Adoptive donor lymphocyte(More)
Quantitative real-time PCR (qPCR) has been proposed as a highly sensitive method for monitoring hematopoietic chimerism and may serve as a surrogate marker for the detection of minimal residual disease minimal residual disease in myelodysplastic syndrome (MDS), until specific methods of detection become available. Because a systematic comparison of the(More)
Enrichment of cell subpopulations is a prerequisite for lineage-specific chimerism analysis (LCA), a frequent approach in follow-up after allo-SCT. An efficient enrichment technique is Magnetic Cell Sorting (MACS) using the AutoMACS separator. However, evaluation of purity, recovery and applicability for PCR-based chimerism analysis of MACS-enriched(More)
Anecdotal clinical cases previously suggested the potential of cytokine-induced killer (CIK) cells as an antileukemic immunotherapy (IT). Here, we report the aggregate experience from three hematology-oncology centers regarding the feasibility, safety and efficacy of interleukin (IL)-15-activated CIK cell treatment for the immunological control of relapse(More)
