Haploidentical transplant in adult patients with acute lymphoblastic leukemia in Argentina: a comparison with matched related and unrelated donors.

We aimed at analyzing the outcome of allogeneic stem cell transplant (ASCT) in adult patients with acute lymphoblastic leukemia (ALL), comparing Haploidentical (Haplo) with HLA-matched (sibling and unrelated) donors. Between 2008 and 2017, we collected data from 236 patients (median age 31 years; range 16-64; 90% HCT-CI 0-1) who underwent unmanipulated ASCT in first complete remission and subsequent remissions in 15 Argentinian centers. Donors were HLA-matched (n = 175; 74%) and Haplo (n = 61; 26%).

A specific subpopulation of mesenchymal stromal cell carriers overrides melanoma resistance to an oncolytic adenovirus.

The homing properties of mesenchymal stromal cells (MSCs) toward tumors turn them into attractive tools for combining cell and gene therapy. The aim of this study was to select in a feasible way a human bone marrow-derived MSC subpopulation that might exhibit a selective ability to target the tumor mass. Using differential in vitro adhesive capacities during cells isolation, we selected a specific MSC subpopulation (termed MO-MSCs) that exhibited enhanced multipotent capacity and increased cell surface expression of specific integrins (integrins α2, α3, and α5), which correlated with an enhanced MO-MSCs adhesiveness toward their specific ligands.

[Evolutionary and bone marrow recovery indicators in bone marrow transplantation after total body irradiation].

Oxidative stress and reticulocyte maturity index (RMI) were studied in 27 patients who underwent bone marrow transplantation (BMT). Plasmatic lipoperoxide levels of those patients with unfavorable evolution were significantly increased on days 12-14 post-transplant (median 1.83 microM, range 0.
