[PMID: 38705885 PMCID: PMC11070414 DOI: 10.1038/s41392-024-01820-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 03/02/2024] [Accepted: 03/27/2024] [Indexed: 05/07/2024] Open
Abstract
Coinfusion of unrelated cord blood (UCB) units in haploidentical hematopoietic cell transplantation (haplo-HCT) (haplo-cord HCT) for hematopoietic malignancies showed promising results in previous reports, but the efficiency of haplo-cord HCT in acute myeloid leukemia (AML) still lacks sufficient evidence. This multicenter, randomized, phase 3 trial (ClinicalTrials.gov NCT03719534) aimed to assess the efficacy and safety of haplo-cord HCT in AML patients. A total of 268 eligible patients aged 18-60 years, diagnosed with measurable residual disease in AML (excluding acute promyelocytic leukemia), with available haploidentical donors and suitable for allotransplantation, were randomly allocated (1:1) to receive haplo-cord HCT (n = 134) or haplo-HCT (n = 134). The 3-year overall survival (OS) was the primary endpoint in this study. Overall median follow-up was 36.50 months (IQR 24.75-46.50). The 3-year OS of Haplo-cord HCT group was better than haplo-HCT group (80.5%, 95% confidence interval [CI]: 73.7-87.9 vs. 67.8% 95% CI 60.0-76.5, p = 0.013). Favorable progression-free survival (70.3%, 95% CI 62.6-78.8 vs. 57.6%, 95% CI 49.6-67.0, p = 0.012) and cumulative incidence of relapse (12.1%, 95% CI 12.0-12.2 vs. 30.3%, 95% CI 30.1-30.4, p = 0.024) were observed in haplo-cord HCT group. Grade 3-4 adverse events (AEs) within two years posttransplantation in the two groups were similar. Haplo-cord HCT patients exhibited a faster cumulative incidence of neutrophil recovery (p = 0.026) and increased T-cell reconstitution in the early period posttransplantation. Haplo-cord HCT can improve OS in AML patients without excessive AEs, which may exert additional benefits for recipients of haplo-HCT.

The Incorporation of Extracellular Vesicles from Mesenchymal Stromal Cells Into CD34 + Cells Increases Their Clonogenic Capacity and Bone Marrow Lodging Ability. Stem Cells 2019; 37:1357-1368. [PMID: 31184411 PMCID: PMC6852558 DOI: 10.1002/stem.3032] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 04/11/2019] [Accepted: 04/20/2019] [Indexed: 12/22/2022]
Abstract
Mesenchymal stromal cells (MSC) may exert their functions by the release of extracellular vesicles (EV). Our aim was to analyze changes induced in CD34+ cells after the incorporation of MSC‐EV. MSC‐EV were characterized by flow cytometry (FC), Western blot, electron microscopy, and nanoparticle tracking analysis. EV incorporation into CD34+ cells was confirmed by FC and confocal microscopy, and then reverse transcription polymerase chain reaction and arrays were performed in modified CD34+ cells. Apoptosis and cell cycle were also evaluated by FC, phosphorylation of signal activator of transcription 5 (STAT5) by WES Simple, and clonal growth by clonogenic assays. Human engraftment was analyzed 4 weeks after CD34+ cell transplantation in nonobese diabetic/severe combined immunodeficient mice. Our results showed that MSC‐EV incorporation induced a downregulation of proapoptotic genes, an overexpression of genes involved in colony formation, and an activation of the Janus kinase (JAK)‐STAT pathway in CD34+ cells. A significant decrease in apoptosis and an increased CD44 expression were confirmed by FC, and increased levels of phospho‐STAT5 were confirmed by WES Simple in CD34+ cells with MSC‐EV. In addition, these cells displayed a higher colony‐forming unit granulocyte/macrophage clonogenic potential. Finally, the in vivo bone marrow lodging ability of human CD34+ cells with MSC‐EV was significantly increased in the injected femurs. In summary, the incorporation of MSC‐EV induces genomic and functional changes in CD34+ cells, increasing their clonogenic capacity and their bone marrow lodging ability. stem cells2019;37:1357–1368

Abstract
We describe results of the strategy, developed by our group, of co-infusion of mobilized haematopoietic stem cells as a support for single-unit unrelated cord blood transplant (dual CB/TPD-MHSC transplants) for treatment of haematological malignancies in adults, and a comparative analysis of results obtained using this strategy and transplants performed with mobilized haematopoietic stem cells from related HLA-identical donors (RTD) for treatment of adults with acute leukaemia and myelodysplastic syndromes. Our data show that the dual CB/TPD-MHSC transplant strategy results in periods of post-transplant neutropenia, final rates of full donor chimerism and transplant-related mortality rates comparable to those of the RTD. Final survival outcomes are comparable in adults transplanted because of acute leukaemia, with different incidences of the complications that most influence these: a higher incidence of infections related to late recovery of protective immunity dependent on T cell functions, and a lower incidence of serious acute graft-versus-host disease and relapses. Recent advances in cord blood transplant techniques allow allogeneic haematopoietic stem cell transplantation (HSCT) to be a viable option for almost every patient who may benefit from this therapeutic approach. Development of innovative strategies to improve the post-transplant recovery of T cells function is currently the main challenge to further improving the possibilities of unrelated cord blood transplantation.

Characterization and transplantation of induced megakaryocytes from hematopoietic stem cells for rapid platelet recovery by a two-step serum-free procedure. Exp Hematol 2009; 37:1330-1339.e5.

Abstract
OBJECTIVE A complete process for mass generation of megakaryocytes from hematopoietic stem cells under serum-free conditions has great clinical potential for rapid platelet reconstruction in thrombocytopenia patients. We have previously reported on the generation of an optimized serum-free medium (serum-free hematopoietic stem cell medium) for ex vivo expansion of CD34(+) cells. Here, we further generated large amounts of functional megakaryocytes from serum-free expanded CD34(+) cells under a complete and optimal serum-free condition for complying with clinical regulations. MATERIALS AND METHODS Serum substitutes and cytokines were screened and optimized for their concentration for megakaryocyte generation by systemically methods. Serum-free induced megakaryocytes were characterized by surface antigens, gene expression, ex vivo megakaryocyte activation ability, and ability of megakaryocyte and platelet recovery in nonobese diabetic/severe combined immunodeficient mice. RESULTS The optimal serum-free megakaryocyte induction medium was Iscove's modified Dulbecco's medium containing serum substitutes (i.e., human serum albumin, human insulin, and human transferrin) and a cytokine cocktail (i.e., thrombopoietin, stem cell factor, Fms-like tyrosine kinase 3 ligand, interleukin-3, interleukin-6, interleukin-9, and granulocyte-macrophage colony-stimulating factor). After induction, induced megakaryocytes expressed CD41a and CD61 surface antigens, nuclear factor erythroid-derived 2 and GATA-1 transcription factors and megakaryocyte activation ability. Importantly, transplantation of induced megakaryocytes could accelerate megakaryocyte and platelet recovery in irradiated nonobese diabetic/severe combined immunodeficient mice. CONCLUSION In conclusion, we have developed a serum-free megakaryocyte induction medium, and the combination of serum-free megakaryocyte and serum-free hematopoietic stem cell media can generate a large amount of functional megakaryocytes efficiently. Our method represents a promising source of megakaryocytes and platelets for future cell therapy.

Abstract
BACKGROUND The NOD/SCID mouse is a widely used model for human cord blood (CB) transplantation. Engraftment is generally estimated with semiquantitative methods, measuring the percentage of human cells among mouse cells. To compare protocols aiming to improve hematopoietic recovery, quantitative methods to enumerate human cells would be preferred. This study describes a single-platform protocol to count human platelets (hPLTs) after transfusion and CB transplantation in the peripheral blood (PB) of the mouse. METHODS With an anti-human CD41 antibody against hPLTs and counting beads, the sensitivity to detect hPLTs in mouse blood by flow cytometry was validated. PLT recovery after hPLT transfusions and PLT kinetics after transplantation with CB CD34+ cells was followed in time in NOD/SCID mice. RESULTS hPLTs could be reliably detected to a level as low as 1 PLT per microL with this single-platform protocol, what appeared to be at least 10 times more sensitive than detection with the dual-platform protocol. To verify the applicability for mouse studies, hPLTs were measured serially in transfusion and transplantation studies in NOD/SCID mice. The results showed that earlier detection of PLT recovery was feasible with the single-platform protocol. CONCLUSION A single-platform flow cytometry method can repeatedly measure low numbers of circulating hPLTs in the PB of the same mouse. This method may be helpful in search of new protocols aiming at accelerating PLT recovery after CB transplantation, but also in a number of clinical settings, such as monitoring PLT reconstitution after hematopoietic stem cell transplantation.

Abstract
BACKGROUND Prior studies have demonstrated that relatively immature hematopoietic stem cells, including CD34(+) CD38(-) and CD34(+) HLA-DR(-) subsets, correlate with short-term hematopoietic reconstruction (SHR) after transplantation. The aim of this study was to investigate whether these immature CD34(+) subsets also correlate with long-term hematopoietic reconstitution (LHR) in recipients of ABMT. METHODS We examined stem cell grafts from 58 patients with B-cell lymphoma or CLL who underwent ABMT after myeloablative conditioning. We determined whether total mononuclear cell dose (MNC), colony-forming unit-granulocyte-monocyte (CFU-GM), CD34(+) cell dose and CD34(+) cell subsets (CD34(+) CD38(-) and CD34(+) HLA-DR(-) were associated with SHR and/or LHR. Time to neutrophil engraftment (TNE) and time to platelet engraftment (TPE) were used to measure SHR, while platelet counts at day 100 and 1 year post-ABMT were used as indicators for LHR. RESULTS AND DISCUSSION CD34(+) cell dose and CD34(+) cell subsets were significantly associated with SHR. However, at day 100 and 1 year post-transplant only total CD34(+) cell dose was associated with LHR. The association of total CD34(+) cell dose with LHR persisted after adjusting for age, sex and disease. None of the CD34(+) cell subsets analyzed showed evidence of significant association with LHR.

Abstract
OBJECTIVES Hematopoietic recovery, in particular platelet reconstitution, can be severely delayed after transplantation with cord blood (CB) stem cells (SC). Expansion of CB SC may be one way to improve the recovery, but there is concern that ex vivo expansion compromises the repopulating ability of SC. METHODS We used a short-term expansion protocol with TPO as single growth factor. The expanded cells were tested in the NOD/SCID mouse model and both platelet recovery and repopulation capacity were examined and compared with unexpanded CD34+ CB cells of the same CB donor. RESULTS Platelet recovery started 1 week earlier in mice transplanted with TPO-expanded CD34+ cells and at days 5 and 8 after transplantation, 6.2 +/- 2.6 and 13.9 +/- 6.7 plt/microL were observed, respectively. At similar time intervals 0.0 and 1.5 +/- 0.2 plt/microL respectively were detected in mice receiving the unmanipulated CD34+ grafts. This was accompanied by a higher number of CFU-Mk in the bone marrow (BM) 7 days after transplantation. Moreover, the BM engraftment and the lineage differentiation of human cells at 6 weeks after transplantation was similar, suggesting that long-term engraftment was not compromised by the expansion procedure. CONCLUSION Ex vivo expansion with TPO as single growth factor results in an accelerated platelet recovery in NOD/SCID mice and appears not to affect the long-term repopulation capacity.
