The efficiency of five different cryopreservation protocols (our original controlled-rate and noncontrolled-rate protocols) was evaluated on the basis of the recovery after thawing of very primitive pluripotent hemopoietic stem cells (MRA(CFU-GM), pluripotent progenitors (CFU-Sd12) and committed granulocyte-monocyte progenitors (CFU-GM) in mouse bone(More)
The multiple effects of interleukin-1 (IL-1) on hematopoietic cells are mainly documented in disturbed hematopoiesis, but its production and participation during constitutive hematopoiesis are still unproven. To assess the involvement of IL-1 in the regulation of steady-state hematopoiesis in vivo, we have investigated the consequences of IL-1 receptor(More)
Low O(2) concentration (1%) favors the self-renewal of hematopoietic stem cells and inhibits committed progenitors (CFC). Since IL-6 influences both stem cells and committed progenitors at 20% O(2), we studied its effects in cultures at 1% O(2). The pre-CFC activity in Lin- population of mouse bone marrow was analyzed following 10 days of serum-free culture(More)
We studied hematopoiesis in bone marrow and blood of CBA mice following infection with Toxoplasma gondii. Our data showed that acute infection with the virulent RH strain was associated with leucopenia, thrombocytopenia and bone marrow hypoplasia while, in spite of the infection-induced damage of the granulocyte cell lineage, in bone marrow stimulated(More)
Pinworm parasites commonly infect laboratory mice with high prevalence even in well-managed animal colonies. Although often considered as irrelevant, these parasites if undetected may significantly interfere with the experimental settings and alter the interpretation of final results. There are a few reports documenting the effects of pinworms on research(More)
INTRODUCTION Mesenchymal stem cells (MSCs) are a promising tool for regenerative medicine, but due to the heterogeneity of their populations, different sources and isolation techniques, the characteristics defining MSCs are inconsistent. OBJECTIVE The aim of this study was to compare the characteristics of MSCs derived from two different human tissues:(More)
Psychological stress affects different physiological processes including haematopoiesis. However, erythropoietic effects of chronic psychological stress remain largely unknown. The adult spleen contains a distinct microenvironment favourable for rapid expansion of erythroid progenitors in response to stressful stimuli, and emerging evidence suggests that(More)
Stress evokes an integrated neuroendocrine response perturbing the homeostasis of different physiological systems. In contrast to well established physiologica linteractions between neuroendocrine and immune systems during chronic stress, there has been relatively little information on the effects of psychological stress on erythroid cells. Since(More)
It has long been known that T cells have the potential to modulate hematopoietic response in different ways. More recently, the importance of interleukin (IL)-17-secreting Th17 cells in T-cell-mediated regulation of hematopoiesis was indicated by the line of evidence that IL-17 links T-cell function and hematopoiesis through stimulation of granulopoiesis(More)
The influence of recombinant human IL-17 on granulocyte-macrophage (CFU-GM) and erythroid (BFU-E and CFU-E) progenitors and the release of IL-1alpha/beta, IL-6 and erythropoietin (EPO) was estimated in the bone marrow cells obtained from normal and sublethally irradiated mice. In normal mice IL-17 increased CFU-GM and BFU-E and reduced CFU-E derived(More)
