INTRODUCTION: High-dose chemotherapy with autologous hematopoietic stem cell transplantation (auto-HSCT) improves the outcome of patients with multiple myeloma (MM). It seems that auto-HSCT is also a feasible therapeutic option in MM dialysis-dependent (MMDD) patients. However, to perform transplantation, a sufficient number of stem cells must be collected. MATERIALS AND METHODS: Given that data on mobilization of auto-HSC efficacy and safety in dialysis-dependent patients are limited, we report data from all Polish Centers belonging to the Polish Multiple Myeloma Group...

Mesenchymal stem cells (MSCs) have immunomodulatory functions and differentiation capacity, and their clinical use is increasing in veterinary species. Although MSCs have been applied in the treatment in various inflammatory diseases, mechanistic research on feline MSCs is lacking. Accordingly, in this study, we aimed to investigate the immunomodulatory mechanisms of MSCs isolated from feline adipose tissue (fATMSCs). fATMSCs from healthy cats were cultured in an appropriate manner and cocultured with transwell-separated allogeneic feline peripheral blood mononuclear cells (fPBMCs) and RAW264...

Alloreactive CD8+ T-cells mediate the curative graft-versus-leukaemia effect, the anti-viral immunity and graft-versus-host-disease (GvHD) after allogeneic stem cell transplantation (SCT). Thus, immune reconstitution with CD8+ T-cells is critical for the outcome of patients after allogeneic SCT. Certain miRNAs such as miR-146a or miR-155 play an important role in the regulation of post-transplant immunity in mice. While some miRNAs e.g. miR-423 or miR-155 are regulated in plasma or full blood during acute GvHD also in man, the relevance and expression profile of miRNAs in T-cells after allogeneic SCT is unknown...

The use of blood derived eye drops for the treatment of ocular surface disorders has become increasingly popular in recent years. The mechanism of action is the stimulation of cellular proliferation and migration by supplying an active mixture of growth factors and cytokines at the ocular surface, thus mimicking the function of the lacking natural tears. Blood derived eye drops have been used in the last decades for the treatment of a variety of ocular surface diseases, including mainly dry eye disease, persistent corneal epithelial defect, corneal ulcer, ocular surface burn, recurrent corneal erosion and limbal stem-cell deficiency...

Sickle cell anemia (SCA) is a monogenic disease of high mortality, affecting millions of people worldwide. There is no broad, effective, and safe definitive treatment for SCA, so the palliative treatments are the most used. The establishment of an in vitro model allows better understanding of how the disease occurs, besides allowing the development of more effective tests and treatments. In this context, iPSC technology is a powerful tool for basic research and disease modeling, and a promise for finding and screening more effective and safe drugs, besides the possibility of use in regenerative medicine...

Artificial skin has achieved considerable therapeutic results in clinical practice. However, artificial skin treatments for wounds in diabetic patients with impeded blood flow or with large wounds might be prolonged. Cell-based therapies have appeared as a new technique for the treatment of diabetic ulcers, and cell-sheet engineering has improved the efficacy of cell transplantation. A number of reports have suggested that adipose-derived stem cells (ASCs), a type of mesenchymal stromal cell (MSC), exhibit therapeutic potential due to their relative abundance in adipose tissue and their accessibility for collection when compared to MSCs from other tissues...

High-dose melphalan (HDM) and autologous blood stem cell transplantation (ABSCT) is an effective treatment for transplantation-eligible patients with systemic light chain (AL) amyloidosis. Whereas most centers use granulocyte colony-stimulating factor (G-CSF) alone for mobilization of peripheral blood stem cells (PBSC), the application of mobilization chemotherapy might offer specific advantages. We retrospectively analyzed 110 patients with AL amyloidosis who underwent PBSC collection. Major eligibility criteria included age <70 years and cardiac insufficiency New York Heart Association ≤III°...

Transplantation of a biosynthetic nerve conduit carrying neuro-protective cytokines is promising for treating peripheral nerve injury. Here we developed a novel strategy for repairing sciatic nerve injury by EPO-loaded Chitosan nerve conduit (EPO/Chi) and sandwiched-in transplantation of mesenchymal stem cells (MSCs). Then, the beneficial effect of EPO/Chi + MSCs on nerve regeneration was also further investigated by in vitro cellular experiments. In vivo experiment showed that combination of EPO-loaded Chitosan nerve conduit with MSCs could significantly accelerate nerve healing and improve morphological repair...

Gedunin is one of the major compounds found in the neem tree (Azadirachta indica). In the present study, antiproliferative potential of gedunin was evaluated in human embryonal carcinoma cells (NTERA-2, a cancer stem cell model) and peripheral blood mononuclear cells (PBMCs), using Sulforhodamine (SRB) and WST-1 assays, respectively. The effects of gedunin on expression of heat shock protein 90 (HSP90), its cochaperone Cdc37, and HSP client proteins (AKT, ErbB2, and HSF1) were evaluated by real-time PCR. Effects of gedunin on apoptosis were evaluated by (a) apoptosis associated morphological changes, (b) caspase 3/7 expression, (c) DNA fragmentation, (d) TUNEL assay, and (e) real-time PCR of apoptosis related genes (Bax, p53, and survivin)...

Peripheral blood mononuclear cells (PBMCs) were collected from a clinically characterized patient with autism spectrum disorder (ASD). The PMBCs were reprogrammed with the human OSKM transcription factors using the Sendai-virus delivery system. The pluripotency of transgene-free iPSCs was verified by immunocytochemistry for pluripotency markers and by spontaneous in vitro differentiation towards the 3 germ layers. Furthermore, the iPSC line showed normal karyotype. Our model might offer a good platform to study the pathomechanism of ASD, also for drug testing, early biomarker discovery and gene therapy studies...
