Rodriguez et al. present in this issue a cost-effectiveness analysis of Defibrotide (Defitelioi) for the treatment severe veno-occlusive disease context hematopoietic stem cell transpl...

Changes in fecal microbiota affect the incidence and extent of graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). Most patients with hematological mal...

BACKGROUND Hematopoietic stem cells are retained within discrete bone marrow niches through the effects of cell adhesion molecules and chemokine gradients. However, a small proportion of hematopoietic stem cells can also be found trafficking in the peripheral blood. During induced stem cell mobilization a proteolytic microenvironment is generated, but whether proteases are also involved in phys...

Hematopoietic stem cell (HSC) generation in the aorta-gonad-mesonephros region requires HSC specification signals from surrounding microenvironment. In zebrafish, PDGF-B/PDGFRβ signaling controls hematopoietic stem/progenitor (HSPC) and is required niche. Little known about murine HSPC vivo whether involved. Here we show that PDGFRβ expressed distinct perivascular stromal layers mid-gestation d...

Потенциальная роль вирусов человека и бактериофагов после трансплантации гемопоэтических стволовых клеток: мини-обзорPossible role of intestinal human viruses and bacteriophages following hematopoietic stem cell transplantation: a mini-review

objective: nowadays, cord blood hematopoietic stem cells (hscs) are known as a valuable source for bone marrow transplantation but unfortunately their insufficient number is a limiting factor for using them in adult bone marrow transplantation. cord blood hcss expansion is an approach to overcome this problem, by inducing their self-renewal. tgf-b signaling pathway is a key inhibitory agent for...

Hematopoietic development and vascular development are closely related physiological processes during vertebrate embryogenesis. Recently, endothelial-to-hematopoietic transition (EHT) was demonstrated to be critical for hematopoietic stem and progenitor cell induction, but its underlying regulatory mechanisms remain poorly understood. Here we show that thrombin receptor (F2r), a protease-activa...

objective: receptor activator of nuclear factor-kappa b ligand (rankl) appears to be an osteoclast-activating factor, bearing an important role in the pathogenesis of multiple myeloma. some studies demonstrated that u-266 myeloma cell line and primary myeloma cells expressed rank and rankl. it had been reported that the expression of myeloid and monocytoid markers was increased by co-culturing ...

Stem cell therapies may be valuable in treatment of inflammatory bowel disease (IBD). Here we focus on two very different types of stem cells - hematopoietic stem cells and mesenchymal stem cells. Myeloablation and hematopoietic stem cell transplantation alter host immune response by reconstituting the recipient's blood cell lines with donor cells. Autologous hematopoietic reconstitution may "r...

For postnatal growth and regeneration of skeletal muscle, satellite cells, a self-renewing pool of muscle stem cells, give rise to daughter myogenic precursor cells that contribute to the formation of new muscle fibers. In addition to this key myogenic cell class, adult skeletal muscle also contains hematopoietic stem cell and progenitor cell populations which can be purified as a side populati...
