Project description:Cell-cell communication between keratinocytes and fibroblasts is essential for skin homeostasis, regulation and regeneration. How extracellular cytokine signaling, intra-cellular protein signaling and transcriptional regulation initiate and maintain this communication is still largely unknown. Here, we study in vitro the secretome and transcriptome dynamics that establish double paracrine cell-cell communication between primary human keratinocytes and fibroblasts. We find that keratinocyte-derived interleukin 1α initiates the cell communication, eliciting a constitutive NF-κB-mediated inflammation response in the fibroblasts. Their resulting transcriptome response over at least 12 hours induces a fibroblast secretome capable of enhancing keratinocyte migration. Applying partial least square regression to secretome perturbation experiments using recombinant proteins or antibodies demonstrates the synergistic interaction of early and late secreted inflammatory CC and CXC chemokines as well as IL6, whose relative composition directly controls keratinocyte migration. Conversely, inhibiting individual cytokines during cell-communication abrogates the keratinocyte phenotype. Hence, only the simultaneous activity of multiple inflammatory cytokines together with prolonged inflammatory response in the fibroblasts lead to increased keratinocyte migration after double paracrine cell communication, putatively serving as safeguard mechanisms for proper skin regeneration.

Project description:Paracrine signals relayed between heterogenous cell types through small and large extracellular vesicles promote cancer cell growth, invasion and metastasis. Microplasts, also called as cytoplasts or cytokineplasts are large extracellular vesicles (0.5-11µm diameter) originating from migratory cells. Microplasts are known to be associated with invasive phenotypes of cancer cells and promote metastasis. Treatment with macrophage conditioned medium induces significant shedding of microplasts from MCF-7 breast adenocarcinoma cells. To characterise microplasts and to study their potential role in intercellular communication in cancer, we isolated microplasts derived from macrophage conditioned medium treated MCF-7 cells and investigated their protein cargo through LC-MSMS.

Project description:Melanoma is an aggressive cancer typically arising from transformation of melanocytes residing in the basal layer of the epidermis, where they are in direct contact with surrounding keratinocytes. The role of keratinocytes in shaping the melanoma tumor microenvironment remains understudied. We previously showed that temporary loss of the keratinocyte-specific cadherin, Desmoglein 1 (Dsg1) controls paracrine signaling between normal melanocytes and keratinocytes to stimulate the protective tanning response. Here, we provide evidence that melanoma cells hijack this intercellular communication by secreting factors that keep Dsg1 expression low in surrounding keratinocytes, which in turn generate their own paracrine signals that enhance melanoma spread through CXCL1/CXCR2 signaling. Evidence suggests a model whereby paracrine signaling from melanoma cells increases levels of the transcriptional repressor Slug, and consequently decreases expression of the Dsg1 transcriptional activator Grhl1. Together, these data support the idea that paracrine crosstalk between melanoma cells and keratinocytes resulting in chronic keratinocyte Dsg1 reduction contributes to melanoma cell movement associated with tumor progression.

Project description:Background: The hES-T3 cell line with normal female karyotype was used to differentiate into autogeneic fibroblast-like cells (T3HDF) as feeder to support the undifferentiated growth of hES-T3 cells (T3/HDF) for 14 passages. A feeder-free culture on Matrigel in hES medium conditioned by these autogeneic feeder cells (T3HDF) was established to maintain the undifferentiated growth of hES-T3 cells (T3/CMHDF) for 8 passages. Results: The gene expression profiles of mRNAs, microRNAs and proteins between the undifferentiated T3/HDF and T3/CMHDF cells were shown to be very similar, and their expression profiles were also found to be similar to those of T3/MEF and T3/CMMEF cells grown on MEF feeder and feeder-free Matrigel in MEF-conditioned medium, respectively. The abundantly expressed genes of T3/HDF, T3/CMHDF, T3/MEF and T3/CMMEF cells were found to play prominent roles in signaling pathways and GO process networks. The miR-302/367 cluster and miR-371/372/373 cluster were extremely abundantly expressed in undifferentiated T3/HDF and T3/CMHDF as well as T3/MEF andT3/CMMEF cells. The undifferentiated state of T3/HDF and T3/CMHDF cells was evidenced by the very high expression levels of ¡§stemness¡¨ genes and low expression levels of differentiation markers of ectoderm, mesoderm and endoderm in addition to the strong staining of OCT4 and NANOG. Conclusion: The T3HDF feeder and T3HDF-conditioned medium were able to support the undifferentiated growth of hES cells, and they would be useful for drug development and toxicity testing in addition to the reduced risks of xenogeneic pathogens when used for medical applications such as cell therapies. Keywords: genetic modification In this investigation, both miRNA and mRNA expression profiles from human embryonic stem cells (hES-T3) grown on MEF feeder (T3_MEF), feeder-free Matrigel in MEF-conditioned medium (T3_CMMEF), T3HDF (hES-T3 differentiated fibroblast-like cells) feeder and feeder-free Matrigel in T3HDF-conditioned medium were quantitatively determined. Several target genes of T3BA and T3CM cells-specific miRNAs were identified. ***This submission represents the mRNA expression component of the study only***

Project description:Endometriosis is an inflammatory disease and bone marrow-derived cells are abundant in endometriotic lesions and in the peritoneal fluid of women with the disease. This study tested the hypothesis that reciprocal communication occurs between macrophages and cultured human endometrial stromal cells and that this communication contributes to the pathology of endometriosis. Changes in gene expression elicited by exposure to factors secreted by the opposing cell type were measured by DNA microarray to test this hypothesis. 716 named genes were differentially expressed in cultured endometrial stromal cells in response to factors secreted by macrophages. Genes that were up-regulated included IL8/CXCL8, MMP3, phospholamban, CYR61/CCN1, CTGF/CCN2, tenascin C, and NNMT, whereas integrin alpha 6 was down-regulated. In contrast, 15 named genes were differentially expressed in macrophages in response to factors secreted by cultured endometrial stromal cells. The data document reciprocal communication between macrophages and endometrial stromal cells and suggest that interaction with macrophages stimulates the expression of genes in endometrial stromal cells that contribute to migration, adhesion, invasion, neovascularization and mitosis of endometrial cells that may support the establishment of endometriosis. Experiment Design: Goal of the experiment: To examine reciprocal communication between a telomerase-immortalized human endometrial stromal cell line (THESC, ATCC #CRL-4003) and U-937 macrophages (ATCC #CRL-1593.2 treated with phorbol ester to stimulate differentiation), and also to assess the response of THESC cells to estrogen plus progesterone. Keywords: human, cultured endometrial stromal cell line, macrophage Experimental factors: hormone treatment and treatment with macrophage-conditioned medium of endometrial stromal cells, treatment of macrophages with endometrial stromal cell conditioned medium Experimental design: T HESC cells were grown in phenol red-free DMEM/F12 medium supplemented with 1% ITS+, 10% charcoal-dextran treated fetal bovine serum albumin, 1% pen/strep, and 500 ng/ml puromycin. THESC cells were treated for 8 days with vehicle (0.1% ethanol) or estradiol (10-8 M) plus progesterone (10-7 M medroxyprogesterone acetate). On day 6, serum was removed from the culture medium. On day 7, half of the cells were treated with U-937 macrophage-conditioned medium for 24 hours. The cells were harvested and RNA extracted on day 8. The experiment was repeated with three different passages of cells (passages 9, 11, and 13) to yield an experimental n of 3. The four groups of cells were vehicle-treated control, estradiol + progesterone, control + macrophage-conditioned medium, and estradiol + progesterone + macrophage-conditioned medium. The monocytic cell line, U-937, was maintained in suspension in RPMI-1640 with 10% fetal bovine serum and 1% pen/strep. The U-937 cells were treated with 32 nM phorbol myristate acetate (PMA) for 48 h to stimulate differentiation into macrophages. The U-937 macrophages were treated with THESC conditioned medium or with non-conditioned control medium. Total RNA was collected after 24 hours. The experiment was repeated with three different passages of cells (passages 7, 9, and 12) to yield an experimental n of 3. The two experimental groups were macrophages treated with non-conditioned control medium and macrophages treated with THESC-conditioned medium. Quality control steps: The cRNA that was synthesized from each cultured cell passage and treatment was used for hybridization to a single CodeLink (Applied Microarrays) whole human genome microarray. Only one sample was hybridized with each slide and only one dye (streptavidin-Alexa 647) was used so no dye swaps were necessary. Bacterial control spikes were used per manufacturer's instructions. Samples used, extract preparation and labelling: The origin of each biological sample: The samples were telomerase-immortalized human endometrial stromal cells and human U-937 monocytic cell line differentiation into macrophages by treatment with phorbol ester. The cell lines were obtained from American Type Culture Collection (#CRL-4003 and #CRL-1593.2). Manipulations of biological samples and protocols used: T HESC cells were grown in culture in phenol red-free DMEM/F12 medium supplemented with 1% ITS+, 2% charcoal/dextran treated fetal bovine serum, 1% penicillin/streptomycin, and 500 ng/ml puromycin. The cells were treated for 8 days with vehicle (0.1% ethanol), estradiol (10-8 M) plus progesterone (10-7 M medroxyprogesterone acetate), vehicle + macrophage-conditioned medium, or estradiol (10-8 M) + progesterone (medroxyprogesterone acetate 10-7 M) + macrophage-conditioned medium. On day 6, serum was removed from the culture medium of all cells. On day 7, half of the cells were treated with macrophage-conditioned medium for 24 hours. The cells were harvested and RNA extracted on day 8. The experiment was repeated with three different passages of cells (passages 9, 11, and 13) to yield an experimental n of 3. The four groups of cells were vehicle-treated control, estradiol + progesterone, control + macrophage-conditioned medium, and estradiol + progesterone + macrophage-conditioned medium. To prepare macrophage-conditioned medium, U-937 (ATCC #CRL-1593.2) cells were grown in RPMI-1640 medium with 10% fetal bovine serum until the cells covered 80% of the flask surface. These U-937 cells were treated with 32 nM PMA for 48 h to stimulate differentiation into macrophages. Differentiated macrophages were maintained in phenol red-free, fetal bovine serum-free DMEM/F12 medium supplemented with 1% penicillin/streptomycin for 48 hours. The cell suspension was centrifuged and the conditioned medium was collected, filtered, and stored at -80C. Before use, macrophage-conditioned medium was supplemented with 1% ITS+ and puromycin. The monocytic cell line, U-937, was maintained in suspension in RPMI-1640 with 10% fetal bovine serum and 1% pen/strep. The U-937 cells were treated with 32 nM PMA for 48 h to stimulate differentiation into macrophages. The differentiated macrophages were treated with THESC conditioned medium or with non-conditioned control medium. Total RNA was collected after 24 hours. Experimental factor: hormone treatment, treatment with macrophage-conditioned medium, and treatment with T-HESC cell conditioned medium Technical protocols: The cells were rinsed and TRI reagent (MRC) was added to the culture flasks. The cells were scraped into centrifuge tubes, bromochloropropane and sodium acetate were added, and the samples were centrifuged to separate the phases. The RNA-containing layer was removed and the RNA purified on an RNeasy extraction column (Qiagen). The sample was treated with an on-column DNase treatment (RNase-free DNase, Qiagen). The purity and quantity were evaluated by an Agilent Bioanalyzer using the RNA 6000 Nanoassay LabChip. Labelled cRNA was prepared using the Message Amp II-Biotin Enhanced Kit from Ambion, following the manufacturer's Instruction Protocol. 1.0 microgram of T-HESC cell total RNA or 2 micrograms of macrophage total RNA was mixed with bacterial control RNA spikes and primed with T7 oligo(dT) primer for 10 min at 70C. (The bacterial control spikes included araB, entF, fixB, gnd, hisB, and leuB.) The first strand of cDNA was synthesized with first strand buffer, dNTP mix, RNase inhibitor, and reverse transcriptase for 2 h at 42C. The second strand cDNA synthesis reaction was prepared using second strand buffer, dNTP mix, DNA polymerase mix, and RNase H; the reaction was carried out for 2h at 16C. The double-stranded cDNA was purified on spin columns included in the Ambion kit. The double-stranded cDNA was mixed with T7 reaction buffer, T7 ATP, T7 GTP, T7 UTP, T7 CTP, biotin-11-UTP, and T7 enzyme mix for the synthesis of cRNA. The cRNA synthesis reaction was terminated after 14h at 37C by purifying the cRNA on spin columns from the Ambion kit. The concentration of cRNA was determined by spectrophotometry. Hybridization procedures and parameters: 10 micrograms of biotinylated cRNA was mixed with fragmentation buffer and heated to 94C for 20 min. The fragmented cRNA was mixed with CodeLink hybridization buffer, loaded on the microarray slides, and hybridized for 18 hours at 37C. The slides were washed in 0.75x TNT (Tris-HCl, NaCl, Tween-20) at 46C for 1h then incubated with streptavidin-Alexa 647 fluorescent dye for 30 min at room temperature. The streptavidin-Alexa 647 fluor was prepared in TNB blocking buffer (0.1M Tris-HCl, 0.15M NaCL, 0.5% NEN Blocking Reagent-PerkinElmer) The slides were then washed 4 times for 5 min each in 1x TNT and twice in 0.05% Tween 20 for 5 sec each. The slides were dried by centrifugation and scanned in an Axon GenePix 4000B scanner.

Project description:Staphylococcus aureus produces the cyclic dipeptides tyrvalin and phevalin (aureusimine A and B, respectively). A previous study reported that S. aureus mutants not capable of producing these compounds were less virulent in vivo through the deranged regulation of virulence factor genes. These findings, however, have been questioned as an unknown mutation in an operon that regulates virulence was discovered in the mutant strain. Here, we report that S. aureus biofilms produce greater amounts of phevalin than their planktonic counterparts. When administered to human keratinocytes, phevalin had no substantial effect on gene expression. Phevalin had no obvious impact on the extracellular metabolome of S. aureus. However, conditioned medium from S. aureus spiked with phevalin resulted in significant differences in keratinocyte gene expression compared to conditioned medium alone. A role for phevalin in manipulating host responses is apparent. Additionally, phevalin is a potential biomarker and/or therapeutic target for chronic, biofilm-based infections. Secreted factors from S. aureus biofilm and planktonic cultures with equivalent population sizes were placed in contact with human HaCaT keratinocytes for 4 hours. Keratinocytes were grown to ~90% confluency.
