Stromal cells mediate retinoid-dependent functions essential for renal development. (1/4669)

The essential role of vitamin A and its metabolites, retinoids, in kidney development has been demonstrated in vitamin A deficiency and gene targeting studies. Retinoids signal via nuclear transcription factors belonging to the retinoic acid receptor (RAR) and retinoid X receptor (RXR) families. Inactivation of RARaplpha and RARbeta2 receptors together, but not singly, resulted in renal malformations, suggesting that within a given renal cell type, their concerted function is required for renal morphogenesis. At birth, RARalpha beta2(-) mutants displayed small kidneys, containing few ureteric bud branches, reduced numbers of nephrons and lacking the nephrogenic zone where new nephrons are continuously added. These observations have prompted us to investigate the role of RARalpha and RARbeta2 in renal development in detail. We have found that within the embryonic kidney, RARalpha and RARbeta2 are colocalized in stromal cells, but not in other renal cell types, suggesting that stromal cells mediate retinoid-dependent functions essential for renal development. Analysis of RARalpha beta2(-) mutant kidneys at embryonic stages revealed that nephrons were formed and revealed no changes in the intensity or distribution of molecular markers specific for different metanephric mesenchymal cell types. In contrast the development of the collecting duct system was greatly impaired in RARalpha beta2(-) mutant kidneys. Fewer ureteric bud branches were present, and ureteric bud ends were positioned abnormally, at a distance from the renal capsule. Analysis of genes important for ureteric bud morphogenesis revealed that the proto-oncogene c-ret was downregulated. Our results suggest that RARalpha and RARbeta2 are required for generating stromal cell signals that maintain c-ret expression in the embryonic kidney. Since c-ret signaling is required for ureteric bud morphogenesis, loss of c-ret expression is a likely cause of impaired ureteric bud branching in RARalpha beta2(-) mutants. (+info)

Establishment and characterization of nurse cell-like stromal cell lines from synovial tissues of patients with rheumatoid arthritis. (2/4669)

OBJECTIVE: To investigate the features of synovial stromal cells established from patients with rheumatoid arthritis (RA), and to define these cells as nurse cells. METHODS: Synovial nurse-like stromal cell lines (RA-SNCs) were established from patients with RA. These cell lines were examined for morphology, pseudoemperipolesis activity, cell surface markers, and cytokine production. The interaction between these RA-SNCs and a synovial tissue B cell clone was also examined. RESULTS: RA-SNCs had nurse cell activity. They spontaneously produced interleukin-6 (IL-6), IL-8, granulocyte colony-stimulating factor, and granulocyte-macrophage colony-stimulating factor. Furthermore, they produced IL-1beta and tumor necrosis factor alpha and expressed higher levels of the other cytokines after coculture with the B cell clone. Proliferation and Ig production by the B cell clone were dependent on direct contact with RA-SNCs. CONCLUSION: These results indicate that the RA-SNCs were nurse cells. The findings suggest that RA-SNCs may play an important role in the pathogenesis of RA by producing large amounts of cytokines and maintaining infiltrating lymphocytes. (+info)

Expression of neurotrophins and their receptors in human bone marrow. (3/4669)

The expression of neurotrophins and their receptors, the low-affinity nerve growth factor receptor (p75LNGFR) and the Trk receptors (TrkA, TrkB, and TrkC), was investigated in human bone marrow from 16 weeks fetal age to adulthood. Using reverse transcription-polymerase chain reaction, all transcripts encoding for catalytic and truncated human TrkB or TrkC receptors were detected together with trkAI transcripts, whereas trkAII transcripts were found only in control nerve tissues. Transcripts for the homologue of the rat truncated TrkC(ic113) receptor were identified for the first time in human tissue. Stromal adventitial reticular cells were found immunoreactive for all neutrophin receptors. In contrast, hematopoietic cell types were not immunoreactive for p75LNGFR but showed immunoreactivity for one or several Trk receptors. TrkA immunoreactivity was found in immature erythroblasts. Catalytic TrkB immunoreactivity was observed in eosinophilic metamyelocytes and polymorphonuclear cells. Truncated TrkB immunoreactivity was found in erythroblasts and megacaryocytes. Immunoreactivity for both catalytic and truncated TrkC receptor was observed in promyelocytes, myelocytes, some polymorphonuclear cells and megacaryocytes. Neutrophin transcript levels appeared higher at fetal than at adult stages, no variation in Trk family transcript levels was observed. The local expression of neurotrophin genes suggests a wide range of paracrine and/or autocrine mode of action through their corresponding receptors within the bone marrow. (+info)

Marker molecules of human endometrial differentiation can be hormonally regulated under in-vitro conditions as in-vivo. (4/4669)

An established cell culture system of isolated human endometrial stromal and epithelial cells has been used to study the effects of oestrogen and progesterone, as well as their antagonists, upon endometrial cells. Normal hormonal regulation in vivo was investigated simultaneously in endometrial tissue samples taken at different phases of the menstrual cycle. Several marker molecules analysed by immunohistochemistry appeared to depend strongly on endocrine regulation and could be traced in culture. Immunohistochemically, basic parameters of cell biology were identified in vitro, e.g. cell proliferation (Ki-67), adhesion molecules (beta3 integrin) and paracrine factors (leukaemia inhibitory factor). The most reliable parameters to assess hormonal influences were oestrogen and progesterone receptor molecules. Immunohistochemical localization could be improved by molecular biological analysis using RT-PCR. In the presence of oestrogen, a significant expression of hormone receptors was also shown by RT-PCR, and withdrawal of oestrogens and addition of gestagen, i.e. medroxyprogesterone acetate, caused receptor downregulation. Addition of the anti-oestrogen ICI 182.780 to cell-culture medium significantly decreased the synthesis of progesterone receptors. (+info)

Expression of the oxytocin receptor in relation to steroid receptors in the uterus of a primate model, the marmoset monkey. (5/4669)

The dynamics of the receptors for oestrogen (ER), progesterone (PR) and oxytocin (OTR) in the marmoset uterus have been analysed throughout the entire cycle and early pregnancy. Uteri obtained during the early, mid/late and late proliferative phase, and the early, mid and late secretory phase and early pregnancy were examined by immunohistochemistry (OTR, ER, PR) and autoradiography (OTR). A massive upregulation of the ER in the cell nuclei of glandular epithelium and stromal cells during the mid proliferative phase was succeeded by a declining staining intensity and positively stained cell number in the secretory phase. PR immunoreactivity increased in the late proliferative phase and early secretory phase, mainly within the cell nuclei, and then declined in both intensity and cell number towards the mid to late secretory phase. Myometrium showed a similar staining pattern for the steroid receptors. OTR were expressed weakly in stroma throughout the entire cycle, increasing slightly in the secretory phase. Glandular epithelium showed positive staining only during the periovulatory period. Myometrial OTR expression was weak during the proliferative phase, increased towards the secretory phase, and was maximal in the late secretory phase. Myometrial tissue adjacent to endometrium was most strongly stained. A cyclic shift evidently occurred in the pattern of steroid receptors, perhaps reflecting the steroid environment or the luteinizing hormone increase associated with ovulation. (+info)

Detection of Kaposi's sarcoma herpesvirus DNA sequences in multiple myeloma bone marrow stromal cells. (6/4669)

Whether Kaposi's sarcoma herpesvirus (KSHV) is associated with multiple myeloma (MM) remains controversial. We assayed for KSHV DNA sequences in long-term bone marrow stromal cells (BMSCs) from 26 patients with MM and 4 normal donors. Polymerase chain reaction (PCR) using primers which amplify a KSHV gene sequence to yield a 233-bp fragment (KS330233 within open reading frame 26) was negative in all cases. Aliquots of these PCR products were used as templates in subsequent nested PCR, with primers that amplify a 186-bp product internal to KS330233. BMSCs from 24 of 26 (92%) patients with MM and 1 of 4 normal donors were KSHV PCR+. DNA sequence analyses showed interpatient specific mutations (2 to 3 bp). Both Southern blot and sequence analyses confirmed the specificity of PCR results. The presence of the KSHV gene sequences was further confirmed by amplifying T 1.1 (open reading frame [ORF] K7) and viral cyclin D (ORF 72), two other domains within the KSHV genome. Immunohistochemical studies of KSHV PCR+ MM BMSCs demonstrate expression of dendritic cell (DC) lineage markers (CD68, CD83, and fascin). Serological studies for the presence of KSHV lytic or latent antibodies were performed using sera from 53 MM patients, 12 normal donors, and 5 human immunodeficiency virus (HIV)/KSHV+ patients. No lytic or latent antibodies were present in sera from either MM patients or normal donors. Taken together, these findings show that KSHV DNA sequences are detectable in BMSCs from the majority of MM patients, but that serologic responses to KSHV are not present. Ongoing studies are defining whether the lack of antibody response is caused by the absence of ongoing infection, the presence of a novel viral strain associated with MM, or underlying immunodeficiency in these patients.

In vitro hematopoietic and endothelial cell development from cells expressing TEK receptor in murine aorta-gonad-mesonephros region. (7/4669)

Recent studies have shown that long-term repopulating hematopoietic stem cells (HSCs) first appear in the aorta-gonad-mesonephros (AGM) region. Our immunohistochemistry study showed that TEK+ cells existed in the AGM region. Approximately 5% of AGM cells were TEK+, and most of these were CD34(+) and c-Kit+. We then established a coculture system of AGM cells using a stromal cell line, OP9, which is deficient in macrophage colony-stimulating factor (M-CSF). With this system, we showed that AGM cells at 10.5 days postcoitum (dpc) differentiated and proliferated into both hematopoietic and endothelial cells. Proliferating hematopoietic cells contained a significant number of colony-forming cells in culture (CFU-C) and in spleen (CFU-S). Among primary AGM cells at 10.5 dpc, sorted TEK+ AGM cells generated hematopoietic cells and platelet endothelial cell adhesion molecule (PECAM)-1(+) endothelial cells on the OP9 stromal layer, while TEK- cells did not. When a ligand for TEK, angiopoietin-1, was added to the single-cell culture of AGM, endothelial cell growth was detected in the wells where hematopoietic colonies grew. Although the incidence was still low (1/135), we showed that single TEK+ cells generated hematopoietic cells and endothelial cells simultaneously, using a single-cell deposition system. This in vitro coculture system shows that the TEK+ fraction of primary AGM cells is a candidate for hemangioblasts, which can differentiate into both hematopoietic cells and endothelial cells.

A novel stromal cell-dependent B lymphoid stem-like cell line that induces immunoglobulin gene rearrangement. (8/4669)

A stroma-dependent B lymphoid cell line (B31-1) has been established by coculturing sorted stem cells on a novel bone marrow stromal cell line (TBR31-1). B31-1 cells express B220, but do not express other B lymphoid differentiation markers including CD43, heat stable antigen (HSA), or surface immunoglobulin (Ig) M (sIgM), and their Ig heavy chain (IgH) gene loci are germ-line in configuration. The addition of interleukin (IL)-7 or coculture with another stromal cell line, ST2, induces D-J rearrangement of the IgH gene and B lymphocyte differentiation markers. B31-1 cells restore an in vivo repopulation activity to lethally irradiated mice, and the repopulated cells differentiate to HSA+ pre-B cells.Continuous coculture results in two distinct populations, B220(-) c-Kit+ cells and B220(+) c-Kit+ cells; B220(-) c-Kit+ cells are self-renewed and differentiate to B220(+) c-Kit+ cells, while B220(+) c-Kit+ cells produce only B220(+) c-Kit+ cells. Both B220(-) and B220(+) cells similarly express the IgH germ-line transcript (Imu), mRNAs for recombinase (TdT, Rag-1, and Rag-2), and lymphoid-specific transcription factors (Pax-5, EBF, E12/E47, Oct-2, and Ikaros), but the DNA binding activity of Pax-5, EBF, Oct-2, and E2A are low in B220(-) cells and while high in B220(+) cells. These results suggest the existence of at least two active states in the IgH locus before the induction of IgH gene rearrangement during B lymphopoietic development. (+info)
