Background aims . In vitro cultured mesenchymal stromal cells (MSC) are characterized by a short proliferative lifespan, an increasing loss of proliferation capacity and progressive reduction of differentiation potential. Laminin-1, laminin-5, collagen IV and fibronectin are important...
Background aims . A phase I trial examined the ability of immunotherapy to mobilize progenitor and activated T cells. Methods . Interleukin (IL)-2 was administered subcutaneously for 11 days, with granulocyte (G)-colony-stimulating factor (CSF) (5 mcg/kg/day) and granulocyte–macrophage (GM)-CSF...
Background aims . Chimerism is an important outcome measure in hematopoietic cell transplantation as well as somatic cell therapy. Commonly used methods to estimate chimerism are restricted by either gender or inefficient sensitivity. In principle, real-time polymerase chain reaction (PCR)-based...
Background aims. The ethical and biologic limitations with current sources of stem cells have resulted in a quest to look for alternative sources of multipotent stem cells of human origin. Amniotic membrane is of interest as a source of cells for regenerative medicine because of its ease of...
Background aims . Natural killer (NK) cell-based adoptive immunotherapy is a promising approach for the treatment of cancer. Ex vivo expansion and activation of NK cells under good manufacturing practice (GMP) conditions are crucial for facilitating large clinical trials. The goal of this study...
Background aims . Mesenchymal stromal cells (MSC) are gaining in popularity as an experimental therapy for a number of conditions that often require expansion ex vivo prior to use. Data comparing clinical-grade MSC from various ages of donors are scant. We hypothesized that MSC from older donors...
Background aims . We evaluated hematopoietic stem cells according to CD34 expression and aldehyde dehydrogenase (ALDH) activity in peripheral blood and apheresis product samples from patients after mobilization with granulocyte–colony-stimulating factor (G-CSF) alone or G-CSF after high-dose...
Background aims . Circulating monocytes have been exploited as an important progenitor cell resource for hepatocytes in vitro and are instrumental in the removal of fibrosis. We investigated the significance of monocytes in peripheral blood stem cells (PBSC) for the treatment of liver cirrhosis....
