Previous studies have shown the relevance of bone marrow-derived MSCs (BM-MSCs) in controlling graft-versus-host disease (GVHD) after allogeneic transplantation. Since adipose tissue-derived MSCs (Ad-MSCs) may constitute a good alternative to BM-MSCs, we have expanded MSCs derived from human adipose tissue (hAd-MSCs) and mouse adipose tissue (mAd-MSCs),(More)
Mesenchymal stromal cells (MSCs) have important immunosuppressive properties, but the mechanisms and soluble factors involved in these effects remain unclear. We have studied prostaglandin-E2 (PGE2) as a possible candidate implied in adipose tissue-derived MSCs (Ad-MSCs) immunosuppressive properties over dendritic cells and T lymphocytes, compared to bone(More)
The ex vivo expansion of hematopoietic progenitors is a promising approach for accelerating the engraftment of recipients, particularly when cord blood (CB) is used as a source of hematopoietic graft. With the aim of defining the in vivo repopulating properties of ex vivo-expanded CB cells, purified CD34(+) cells were subjected to ex vivo expansion, and(More)
Twenty-eight allogeneic BMT patients (16 with acute leukemia, 12 with chronic myeloid leukemia) were included in a single center, prospective, randomized, controlled trial to assess the value of recombinant human erythropoietin (rh-Epo) in this setting. rh-Epo was administered through a central venous catheter as a single bolus injection (days 0-7: 100(More)
Previous clinical trials based on the genetic correction of purified CD34(+) cells with gamma-retroviral vectors have demonstrated clinical efficacy in different monogenic diseases, including X-linked severe combined immunodeficiency, adenosine deaminase deficient severe combined immunodeficiency and chronic granulomatous disease. Similar protocols,(More)
IMPORTANCE OF THE FIELD In the last decade, knowledge of mesenchymal stem cells (MSCs) has evolved rapidly; their immunomodulatory properties and paracrine interactions with specific cell types in damaged tissues and promising results in some clinical applications have made these cells an attractive option for the treatment of certain diseases.

The insertion of suicide genes in donor T lymphocytes constitutes the basis of new approaches aiming at the treatment of the graft-versus-host disease (GVHD), a frequent complication in recipients of allogeneic haematopoietic grafts. In this study we investigated the impact that the ex vivo manipulation required for the retroviral transduction of T cells(More)
Twenty-four patients with multiple myeloma (MM), three (12.5%) in complete remission (CR) and 21 (87.5%) in partial remission (PR) were treated with high-dose chemotherapy (HDCT) (busulfan 12 mg/kg+melphalan 140 mg/m2) as preparative regimen for autologous peripheral blood stem cell (PBSC) transplantation. These cells were previously collected by(More)
