Over the last five years significant progress has been made towards the transfer of foreign genetic material to eukaryotic cells. The eventual aim to devise novel therapeutic strategies to treat human diseases, in particular solid tumours and monogenic disorders associated with various enzyme deficiency states. The easy accessibility and the ability of haemopoetic stem cells to self replicate and repopulate makes them desirable targets for gene transfer. In theory the introduction of a small number of gene modifed haemopoetic progenitor cells can allow therapy of an individual for life without any further intervention...

The liver is known to be the metabolic centre of the organism and is under the control of the central nervous system. It has a peculiar tissue structure and its anatomic localisation defines it as part of the immune system having an individual role in the defence of the organism. The determinant of its particular tissue build-up is the sinusoid system. In addition to hepatocytes, one cell row "endothelium", stellate cells close to the external surface, Kupffer cells tightly to its inner surface, as well as dendritic cells and other cell types (T and B lymphocytes, natural killer and natural killer T-cells, mast cells, granulocytes) are present...

The objective of this work was to study the influence of combined transplantation of stem cells (multypotent mesenchimal stromal and haemopoetic stem cells) on the haemopoesis of old and mature laboratory animals under the condition of ionizing radiation. The result of the experiment shows that under physiological conditions the combined transplantation brings the erithropoesis activation, under the ionizing radiation conditions it brings the erythroid and granulocytopoesis activation. Moreover the combined MMSC and HSC transplantation gives cytoprotective action on the myeloid tissue due to decrease of cyto genically changed cells in the mature animals under the condition of ionizing radiation, but in the old animals this effect can be seen even under physiological condition...

Extramedullary haemopoiesis (EMH) is the abnormal development and growth of haemopoietic tissue outside the bone marrow. It is usually asymptomatic and occurs in the presence of myelodysplastic syndromes. In this report, we describe the first post-traumatic EMH presenting with lower urinary tract symptoms.

Stem cell techniques have facilitated a number of potential uses for such cells in cell therapy and drug development. Studies of the cAMP/protein kinase A (PKA) pathway are widely employed to investigate the effects of a large variety of substances. We assayed the cAMP pathway in human skin-derived mesenchymal stem cells (S-MSC) to evaluate donor to donor variations in response to pharmacological manipulations in vitro. Immunophenotyping of S-MSC revealed that, in general, 95% of S-MSCs were positive for CD90, CD73 and CD105 and negative for the expression of haemopoetic markers CD14, CD45 and human leukocyte antigen-DR (HLA-DR)...

1. The nodules found in the spleen are islands of active haematoplastic tissue. 2. The bone-marrow, at least in the case which has been described, has been the primary focus of disease; some toxin has probably produced a chronic inflammatory change. 3. The bone-marrow, owing to its enormous sclerosis, has lost its haemopoëtic powers totally or to a marked degree and the spleen has reverted to its foetal power to form blood.

Fusarium spp. moulds are common in moderate climate regions of North America, Asia and Europe. They produce hepatotoxic and nephrotoxic mycotoxins, acting like estrogens, impairing hemopoesis and immunosuppressing. Actively dividing skin cells, lymphatic tissue, haemopoetic tissue and gastrointestinal tissue are the most sensitive for these trichothecenes action. The mucosal membrane of the gastrointestinal tract is the first barrier of the organism contacting with foreign antigens like feed proteins, natural toxins, saprophytic and pathogenic microflora and mycotoxins...

The P2X ₇purinoceptor is unique amongst the P2X receptor family in that its activation is able to stimulate the release of mature, biologically active interleukin-1beta (IL-1β), as well as a variety of other proinflammatory cytokines. Coupled with the predominate localisation of this receptor to immunocytes of haemopoetic origin, this receptor is an obvious candidate to play a major and pivotal role in processes of pain and inflammation. Using genetically modified animals that lack the P2X₇ receptor, several investigators have shown that these mice do indeed demonstrate a blunted inflammatory response, and fail to develop pain following both inflammatory and neuropathic insult...

BACKGROUND: Cancer related fatigue (CRF) is common, under-recognised and difficult to treat. There have been trials looking at drug interventions to improve CRF but results have been conflicting depending on the population studied and outcome measures used. No previous reviews of this topic have been exhaustive or have synthesised all available data. OBJECTIVES: To assess the efficacy of drugs for the management of CRF. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (1st Quarter 2007), MEDLINE (1966 to March 2007) and a selection of cancer journals...

Cathepsin E is an aspartic endosomal proteinase, expressed at high levels in some epithelial and haemopoetic cells. The enzyme has been implicated in a variety of functions, including antigen processing. This study documents strain-specific variation in expression of cathepsin E in mice. The levels of cathepsin E protein and message are profoundly decreased in haemopoetic cells from C57BL/6J mice, compared to levels in 129S2/Sv or Balb/c. The deficiency is cell-type-specific, as protein levels in gut are not affected...

Ionising radiation can induce responses within non-exposed neighbouring (bystander) cells which potentially have important implications on the estimates of risk from low dose or low dose rate exposures of ionising radiations. A range of strategies have been developed for investigating bystander effects in vitro for both high-LET alpha particles or low-LET ultrasoft X rays using either partial shielding (grids, half-shields and slits) or by using a co-culture system where two physically separated populations of cells can be cultured together, allowing one population of cells to be irradiated while the second population remains unirradiated...

In vivo and in vitro studies suggest human growth hormone (hGH) receptors on bone marrow stem cells may be biologically active and could be exploited to promote haemopoetic recovery after intensive chemotherapy. Patients with haematological malignancies receiving intensive chemotherapy and requiring hospitalization were randomized in a double-blind, placebo-controlled single-centre trial. Patients were randomly assigned to receive either hGH 500 microg/day or placebo, for 6 weeks. There was no significant difference in patient characteristics at baseline between the placebo and treatment arms...

The structure and putative cellular content of melano-macrophage centres (MMCs) and single macrophages in kidney and spleen of two teleosts, pearl gouramy Trichogaster leeri (Bleeker) and platyfish Xiphophorus maculatus (Günther), are described and compared. The MMCs were confined to the haemopoetic tissue in both species, and were markedly more prominent in pearl gouramy than in platyfish. They were rich in iron-compounds, probably haemosiderin, in the former species, whereas they contained mainly iron-free pigments, probably lipofuscin, in the latter species...

The combination of pegilált interferon plus ribavirin is significantly more effective than conventional interferon plus ribavirin, and is thus the current therapy of choice for patients with chronic hepatitis C. Forty-eight weeks of treatment with combination of pegilált interferon plus ribavirin has produced overall sustained virologic response 54-56% in patients with chronic hepatitis C. This article summarize the new therapy of chronic hepatitis C, the antiviral therapy of hepatitis C virus patients with normal aminotransferase levels, the therapy in patients with compensated cirrhosis and who were nonresponders to previous combination therapy, the effect of antiviral therapy on necroinflammation and fibrosis, and the favourable effect of haemopoetic growth factors on results of antiviral therapy...

Renal cortical fibroblasts have key roles in mediating intercellular communication with neighboring/infiltrating cells and extracellular matrix (ECM) and maintenance of renal tissue architecture. They express a variety of cytokines, chemokines, growth factors and cell adhesion molecules, playing an active role in paracrine and autocrine interactions and regulating both fibrogenesis and the interstitial inflammatory response. They additionally have an endocrine function in the production of epoetin. Tubulointerstitial fibrosis, the common pathological consequence of renal injury, is characterized by the accumulation of extracellular matrix largely due to excessive production in parallel with reduced degradation, and activated fibroblasts characterized by a myofibroblastic phenotype...

AIMS: Recent results generated in a mouse model suggest that tumour angiogenesis/vasculogenesis can be initiated and maintained by bone marrow derived endothelial progenitor cells. This present study investigated the distribution and frequency of CD133 positive endothelial progenitor cells in patients with non-small cell lung cancer (NSCLC) (tumour tissue and tumour free lung regions) and healthy controls using fresh frozen specimens. The novel marker CD133 identifies human haemopoetic precursor cells, in addition to human endothelial progenitor cells...

This paper presents data from an investigation of the mode of action of five different crustacean immunostimulants presented to European lobster (Homarus gammarus) granulocytes cultured in vitro. The experiments were designed to test whether or not the immunostimulants could cause the short-term up-regulation of genes coding for immune proteins without causing the cells to degranulate. Quantitative measurements of mRNA transcript abundance were made using real-time PCR and it was first necessary to isolate the complete gene sequences coding for the proteins prophenoloxidase (proPO), beta-1,3-glucan binding protein (betaGBP) and beta-actin (beta-act) in the lobster...
