BACKGROUND: Blood stem cells (BSCs) are the most primitive cells in the immune system and can be differentiated into many kinds of cells. As the regulatory cells of immune response, dendritic cells (DCs) have been attracted more and more attention in the field of autoimmune diseases. Due to different resources of precursor cells, DCs have different cytokines, ideal cytokine matching,applying orders, and experimental cultured conditions. Furthermore, development, phenotypic expression, and mature degree are still different.OBJECTIVE: To investigate the influence of tumor necrosis factor- α (TNF- a ) and interleukin-4 (IL-4) on the culture system and provide improved method for inducing functional DCs in vitro, derived from cord blood CD34+ hematopoietic precursor cells (HPC).DESIGN, TIME AND SETTING: Observational study, which was performed in the Department of Microbiology and Immunology, Nanjing Medical University from March 2005 to November 2005.MATERIALS: The cord blood was collected from neonatal umbilical cord in the 81 Hospital of Nanjing City. CD34 monoclonal antibody coated magnetic bead system (MACS) was provided by Miltenyi Biotec Company, Germany; human recombinant granulocyte-macrophage colony-stimulating factor (rhGM-CSF), human recombinant interleukin-4 (rhlL-4), and human recombinant tumor necrosis factor-α (rhTNF-α) by Pepro Tech Company, USA.METHODS: CD34+HPC were isolated and purified from umbilical cord blood by using a high-gradient magnetic cell sorting system (MACS). Then the cells were cultured with different culture medium which contained different combinations of cytokines:GM-CSF and TNF-α (GT) or GM-CSF, TNF-α and IL-α (GTI) in order to be induced to differentiate into dendritic cells (DCs).The DCs derived from CD34+HPC were identified for their morphology and phcnotype by FACS and laser scanning con_focal fluorescence microscopy, and also for their abilities of inducing proliferation of allogenic T cells by 3H-TdR incorporation assay.RESULTS: The purity of selected CD34+ cells with MACS was more than 90%. DCs could be obtained from CD34+HPC by the culture in presence of GM-CSF and TNF-α or GM-CSF, TNF- o and IL-4. With the time of culture lasting, the cells expressed lower level surface antigen of CD34 and HLA-DR (P < 0.05), and possessed the phenotypes of DCs characterized by higher expression of CD80, CD86, CD83 and CDIa. At 13-15 days, the cells possessed higher level of phenotypes of DCs compared to 7-9 days and 10-12 days. DCs induced with GTI culture system expressed higher levels of surface antigen CD80, CD86, CD83,CD 1 a and a lower level of CD 14 than those induced with GT culture system. DCs displayed typical morphology and property and expressed higher level surface antigen of CD86 and CD80, especially expressed CD86 when they were induced with proper cytokines of GM-CSF and TNF- α added at 0 hour, and of IL-4 added at 48 hours.CONCLUSION: DCs can be generated from CD34+HPC by proper culture system, the design of GM-CSF + TNF- α + IL-4(GM-CSF and TNF- α were added at 0 hour, IL-4 was added at 48 hours) is preferred.

Objective To investigate the feature brain damage and clinical manifestations in neuromyelitis optica (NMO) patients; To investigate the relationship between serum NMO-IgG antibody and NMO brain damage. Methods Clinical data of 37 NMO patients and their head and spinal cord MRI by 1.5T superconducting MR scanner, were analyzed; serum NMO-IgG antibody were measured by immunofluorescence. Results 17 cases were found to have abnormal signals on MRI, which were mainly in the white matter, pons, medulla, ventricle, aqueduct, and around the corpus callosum; According to pathological changes, brain damage can be divided into scattered irregularity (13 cases), fusion (3 cases),multiple sclerosis-like (1 case) ,with scattered irregularity more common,5 cases had clinical manifestations of brain damage: somnolence, vomiting, diplopia, visual rotation, 11 cases patients with brainstem damage show positive serum NMO-IgG antibodies. Conclusions Brain damage can be seen in half of NMO patients, they often located in the high expression area of AQP4: brain white matter, periventricular,brainstem and so on. Clinical symptoms has nothing to do with the size of lesions but the location, they often occur when brainstem was involved. Serum NMO-IgG is helpful in differentiating NMO with brain damage and MS.
